Litecoin Cash

Litecoin Cash (LCC) is a fork of Litecoin itself utilizing an SHA-256 hashing algorithm. While the initial goal was to focus on bringing back SHA-256, along the way we created "Hive Mining," an agent-based system allowing everyday users to participate in securing and hashing the network to earn real LCC rewards.

I downloaded the latest of [Samourai Wallet]1 (not from Play Store, but from an online APK I found, as I do not have Play Store installed on my phone).

You should never download Samourai Wallet from non-official/shady webpages. They provide the SHA-256 key of the official APK so you can compare that with the APK which you have downloaded before installing it. ([[link]14 )

Two or three days ago, [they removed some privacy features from the wallet]3 because of stupid and irritating Google policies that everyone here hates. They said they were moving to F-Droid soon with the full-featured app. That was nice, but am I wrong or they could have done this before they were forced to trim the app? Devs already know Google was applying these pathetic policies, they just tried to apply for an exception — as stated on their blog post.

AFAIK Samourai Wallet added to Play Store ~2016. Google didn't had that policy back then it came out recently ([[link]15 ) If you know how F-Droid works its really slow to update apps since they build it their own and there are lots of apps to be build in general I am also a huge F-Droid fan don't forget to donate/contribute to F-Droid they are doing an awesome work. Samourai Wallet is still in Alpha and it needs to be updated regularly and be shared fast so Google Play is a decent way to do it also it helps to see statics (default by Google if you have Google Services installed on your phone Samourai don't include any trackers, their Exodus Privacy Report here: [[link]16 ) and improve the app fixing bugs etc. are easier since the feedback mechanism which Google Play has. Also a little but non-important thing is Samourai back-end is currently not open-sourced they are working on that if they would add it to F-Droid now they would probably marked as promoting non-free network not so important but a little note. (I don't mean here that their back-end open sourcing is not important the notice mark on F-Droid is not important. Please don't try to draw the subject here.) They will be added to F-Droid really soon once they hit stable and completely open sourced their back-end.

Another thing I found is people (users) openly contradicting the privacy statements made by Samourai — [this particular one]6 being the most “extreme”, as it comes from what it seems to be an eminence here. I know Bitcoin is not oriented towards privacy and that privacy is very difficult to implement, but this made me think: why, for example, cannot I connect to a trusted node without having to run a full node myself, specially configure it and use a VPN to connect to it? Why there seems to be an interest in promoting transaction casting through Samourai servers? Also, what are Ricochet, STONEWALL and PayNym? I suppose they are their implementation of different Bitcoin Improvement Proposals, but can they be trusted? Some users in this sub say there’s something shady with this app.

They stated that clearly and that's why they are still on Alpha. They have explained to these numerous times ([[link]17 ) Also that's really hard to be a light wallet as you stated that the safest way is running your own node to maximize your privacy. As I told this is why they are still in Alpha once they release their back-end you can run their implementation on your full node and fully bypass their infrastructure. They are also working on a plug&play node ([[link]18 ) For their Ricochet, Stonewall and Paynym features you can have a look at their webpages. ([[link]19 , [[link]20 , [[link]21 ) They are all open-sourced features and processed on the client, not on their servers.

Then, there is [this serious claim]12 from a user saying that Samourai Wallet lost some of his bitcoins. I won’t get into details, but it was kind of scary to me since other users told him they were in the same situation.

Welcome to the Bitcoin world while financial sovereignty is something awesome it comes with huge responsibility don't going to list here examples which people lost a ton of bitcoins from paper wallets, other wallets, mistakes etc. I remember that guy as you can see in the comments Samourai team tried to help him also I and my friends tried to help him lots of hours (the chat history is available on Telegram group if someone wants to see it feel free to join and read it its pretty long btw) I invited him to the group ([[link]22 ) and he was a pretty good guy he didn't accused Samourai but just wanted help. The Github repository is there you can search the code/commit history and see that there is nothing wrong in private key generation the problem isn't on the Samourai side.

A few Paper Wallet questions, SHA-256. /r/Bitcoin

A few Paper Wallet questions, SHA-256. /Bitcoin submitted by BitcoinAllBot to BitcoinAll [link] [comments]

[Request] If all the power spent in bitcoin mining were targeted to SHA-256 breaking instead, how many wallets would it have broken?

EDIT: Just to be clear, I guess the answer is zero since the question is wrong, but I'm thinking more in the lines of "if we converted all the FLOPs ever spent in mining into a proper algorithm for breaking wallets, how many, if any, would we have broken"?

The Wallet Import Format on the Bitcoin wiki has different hash results for their SHA-256 hashes than I'm getting…

On the Wallet Import Format page on the Bitcoin wiki (https://en.bitcoin.it/wiki/Wallet_import_format) it has a hexadecimal string
800C28FCA386C7A227600B2FE50B7CAE11EC86D3BF1FBE471BE89827E19D72AA1D 
And it says that the SHA-256 hash of this is
8147786C4D15106333BF278D71DADAF1079EF2D2440A4DDE37D747DED5403592 
I'm not getting that. I've tried both an online hasher, and Python's hashlib, and I'm not getting that hash. Perhaps is the wiki incorrect? Or perhaps are they using a different hash algorithm than SHA-256?
EDIT:
For clarification, I keep getting
e2e4146a36e9c455cf95a4f259f162c353cd419cc3fd0e69ae36d7d1b6cd2c09 
as the SHA-256 hash.

What is your personal financial strategy and vision of Gridcoin?

I started the 2020 year by totally ignoring what is a blockchain, or a cryptocoin. And once I started Qwant-ing (alt Google) it, it was a matter of a few days that I learned how to CPU and GPU mine. I even got a SHA-256 ASIC warming up my flat. Of course, the more I learned about Bitcoin and other PoW coins, the worse I was feeling about the incredible waste of energy with such useless hashes and the consequences of the greedy speculation against the "smaller" coins. So I got rid of the ASIC and while looking at the web for alternative coins using PoS or similar, I found this project, in which I really get identified. Now I'm a happy math and astronomy cruncher. It's just amazing, to be crunching and at the same time, getting rewarded.
There are plenty of things to contribute to this project, and I feel really motivated to get further involved into it. Now my question concerns the "money" side, the financial stuff. Of course Gridcoin is not Bitcoin, although it seems that Gridcoin has a long story behind. I see potential, mostly due to the very active community, the increasing interest in Distributed Computing (and thus the eventual popularity of the Proof-of-Research concept) and the "seriousness" of this project. But the perpetual inflation and the apparent lack of significant volume exchanges might underestimate its value, strictly speaking of the markets dynamics.
The growing scarcity and popularity of the mainstream coins might also be pushing this coin out of the radar of most of the people, explaining the actual stagnancy of the GRC market. And so, here is where I ask to you: what is your vision of Gridcoin? Do you (personally) bet everything for this project, in terms of investments (GRC-only wallets) and computational resources? Or do you diversify your portfolios, speculating as well in another cryptos/stocks?
I'd really like to hear from you, to know if you're interested (or not) in the money side of the project, and, for the affirmative case, to know why you're here and why you want to stay here. Thank you for your attention and your feedback!

Looking for Technical Information about Mining Pools

I'm doing research on how exactly bitcoins are mined, and I'm looking for detailed information about how mining pools work - i.e. what exactly is the pool server telling each participating miner to do.
It's so far my understanding that, when Bitcoins are mined, the following steps take place:
  1. Transactions from the mempool are selected for a new block; this may or may not be all the transactions in said mempool. A coinable transaction - which consists of the miner's wallet's address and other arbitrary data - that will help create new Bitcoin will also be added to the new block.
  2. All of said transactions are hashed together into a Merkle Root. The hashing algorithm is Double SHA-256.
  3. A block header is formed for the new block. Said block header consists of a Version, the Block Hash of the Previous Block in the Blockchain, said Merkle Root from earlier, a timestamp in UTC, the target, and a nonce - which is 32 bits long and can be any value from 0x00000000 to 0xFFFFFFFF (a total of 4,294,967,296 nonce values in total).
  4. The nonce value is set to 0x00000000, and said block header is double hashed to get the Block Hash of the current block; and if said Block Hash starts with a certain number of zeroes (depending on the difficulty), the miner sends the block to the Bitcoin Network, the block successfully added to the blockchain and the miner is awarded with newly created bitcoin.
  5. But if said Block Hash does not start with the required number of zeroes, said block will not be accepted by the network, and the miner Double Hashes the block again, but with a different nonce value; but if none of the 4,294,967,296 nonce values yields a Block Hash with the required number of zeroes, it will be impossible to add the block to the network - and in that case, the miner will either need to change the timestamp and try all 4,294,967,296 nonce values again, or the miner will need to start all over again and compose a new block with a different set of transactions (either a different coinable transaction, a different set of transactions from the mempool, or both).
Now, what I'm trying to figure out is what exactly each miner is doing differently in a mining pool, and if it is different depending on the pool.
One thing I've read is that a mining pool gives each participating miner a different set of transactions from the mempool.
I've also read that, because the most sophisticated miners can try all 4,294,967,296 nonce values in less than a fraction of a second, and since the timestamp can only be updated every second, the coinbase transaction is used as a "second nonce" (although, it is my understanding that, being part of a transaction, if this "extra nonce" is changed, all the transactions need to be double hashed into a new Merkle Root); and I may have read someplace that miners could also be given the same set of transactions from the mempool, but are each told to use a different set of "extra nonce" values for the coinbase transaction.
Is there anything else that pools tell miners to do differently? Is each pool different in the instructions it gives to the participating miners? Did I get anything wrong?
I want to make sure I have a full technical understanding of what mining pools are doing to mine bitcoin.

What is Blockchain Technology?

What is Blockchain Technology?
The original article appeared here: https://www.securities.io/what-is-blockchain-technology/
Its been almost ten years since Satoshi Nakamoto first introduced Blockchain technology to the world in his 2008 Bitcoin Whitepaper. Since that time, these revolutionary networks have gained popularity in both the corporate and governmental sectors. This growth is easily explained when you consider that blockchain technology provides the world with some unique advantages that were previously unimaginable. Consequently, today, you can find blockchain technology in nearly every sector of the global economy.

What is Blockchain Technology?

A blockchain is a network of computers that share a distributed ledger across all network participants (nodes). This strategy is far different than say, fiat currencies that originate from a centralized authority figure. Importantly, this ledger keeps an unbroken chain of transactions since the birth of the network. This “chain” of transactions grows larger as new “blocks” of transactions are approved and added to it.
Bitcoin Whitepaper
In order to approve new transactions, each node works together with others to validate new blocks. Additionally, the nodes also validate the current state of the entire blockchain. In order for a new block of transactions to be added to the blockchain, they must receive approval from 51% of the network’s nodes. Nodes are also referred to as miners. In this manner, blockchain networks are decentralized networks that provide unmatched security to the world of digital assets.

Security via Decentralization

Decentralization is an important aspect of blockchain technology because it makes these revolutionary ledgers immutable and unalterable. In fact, since there is no centralized attack vector, hacking a blockchain is nearly impossible. The larger the blockchain network, the more secure the data on it remains.
For example, let’s look at the world’s largest blockchain, Bitcoin. Currently, the Bitcoin blockchain has over 10,000 active nodes located across the globe. This distribution means that in order for an attacker to alter even just one tiny piece of information on the blockchain, they would need to successfully hack 5,000+ computers at once.
While this task may not be impossible for the quantum computers of the future, it’s so unprofitable that it makes no sense to even attempt such a monumental task. Additionally, on top of successfully hacking 5000+ computers at once, an attacker would also need a supercomputer to recalculate the new blockchain transactions in time to introduce them into the network. It would literally be more affordable to create a new cryptocurrency from scratch.

Consensus Mechanisms

One of the reasons why blockchain networks are so secure is the integration of consensus mechanisms. Consensus mechanisms are cryptographic protocols that leverage the participants of a blockchain network in securing its data. In the case of Bitcoin, the Proof-of-Work (PoW) consensus mechanism is used.

Proof-of-Work (PoW)

The Proof-of-Work consensus mechanism was revolutionary to the world of cryptography when it was first introduced years prior by Adam Back in his Hashcash whitepaper. In the concept, Back describes the integration of a mathematical equation to the network’s security protocols. In this way, every computer can show “proof” of their work securing the network.

Miner Rewards

It’s important to understand that nodes receive a reward for their mining efforts. These rewards adjust automatically depending on the network’s difficulty and value. In the case of Bitcoin, miners originally received 50 Bitcoin for their efforts. Today, this seems like fortune, but back in 2009, Bitcoin was only worth pennies. As the value of the token rises and the network goes, the mining rewards shrink. Today, Bitcoin miners receive 6.5 BTC if they add the next block to the chain.

SHA-256

Notably, every node validates and secures the blockchain, but only one gets to add the next block of transactions to the network. To determine who the next miner is that gets to add this block, every computer competes in a mathematical race to figure out the PoW equation. In the case of Bitcoin, the equation is known as SHA-256. Importantly, the first SHA algorithm dates back to Hashcash. This early version of the equation was known as SHA-1.
Notably, the SHA-256 equation is so difficult that it’s easier and more efficient for your computer to just make random guesses rather than attempting to figure out the equation directly. The answer to the equation must begin with a predetermined amount of 0s. In the Bitcoin blockchain, the equation’s answer must start with four zeros. However, if the network’s congestion rises, so does the difficulty of these equations. This difficulty adjusts by the addition of another zero at the beginning of the required SHA-256 answer.
Similarly to traditional commodities such as gold, there are costs that are associated with the creation and introduction of these digital assets into the market. These random guesses utilize intense computational power. This power equates to real-world costs such as electricity bills. Studies have shown that securing the Bitcoin network can use more electricity than required by entire countries. Luckily, over 80% of Bitcoin’s power consumption comes from renewable sources such as solar or hydroelectric. This cost of mining also adds measurable value to each Bitcoin.

Miners

As Bitcoin began to gain in profitability, its network’s computing power expanded significantly. In the beginning, nodes, also known as miners, could mine for Bitcoin using nothing more than your home PC. Eventually, miners realized that graphic cards were far better at the repetitive guessing required to figure out the SHA-256 algorithm. This led to a computational race in the market.

ASIC

Eventually, large blockchain firms such as Bitmain introduced Application Specific Integrated Circuit (ASIC) miners into the equation. These purpose-built miners were thousands of times more efficient at guessing the SHA-256 algorithm than the GPUs and CPUs before them. Consequently, their introduction created a scenario in which the average miner now needed to invest thousands in mining equipment to stay relevant.

Mining Pools

Luckily, some creative minds in the field began to think of ways to level the playing field out again. They developed “mining pools.” A mining pool is a network of miners that all share computational power for the common goal of mining blockchain transactions. Importantly, mining pool participants receive a percentage of the reward based on their contributions to the network’s overall hash (computational power).
Importantly, over the last three years, there has been a push to move away from power-hungry consensus mechanisms such as PoW. This desire to secure blockchains in a more efficient manner has led to the development of some truly unique consensus mechanisms in the sector.

Proof-of-Stake (PoS)

The Proof-of-Stake mechanism does away with the difficult mathematical algorithms and instead utilizes a more psychological approach to securing the network. In a PoS blockchain, users don’t need to compete mathematically to add the next block to the blockchain. Instead, PoS users “stake” their coins via network wallets to secure the network. The way staking works is simple.
Keeping a certain amount of coins in your wallet allows you to participate in transaction validations. The more coins you stake, the more likely the chances are you get to add the next block of transactions to the network. In most PoS systems, a miner from those with the most tokens staked at the time receives the chance to add the blocks.
The advantages of a PoS consensus mechanism are immediately evident. For one, you don’t need to pour tons of resources into your network to keep it safe. Additionally, since nodes are chosen based on their amount of staked coins, there is never a scenario in which a node gains anything from validating incorrect transactions. Basically, a hacker would have to fully invest in the cryptocurrency prior to attacking the network. In this way, PoS systems create a huge deterrent to attackers.

The Future of Blockchain Technology

Blockchain technology has come a long way from its early days as a means to secure cryptocurrency networks. Today, blockchain technology has numerous uses across every type of industry imaginable. Specifically, blockchain programs have impacted the logistical, financial, and data security sectors in a major way.

Blockchain Technology Logistics

Blockchain logistical systems are more efficient and cost-effective to operate than traditional paper-based models. In fact, the immutable and unalterable nature of blockchain tech makes it ideally suited to logistical tasks. Soon, you may be able to ascertain much more information regarding the creation and delivery of your products thanks to these new-age systems emerging.

Fundraising

Blockchain technology has also altered the way in which businesses raise funds. In a traditional corporate crowdfunding strategy such as an IPO, companies must balance between cost-effectiveness and participation. The inability to process smaller transactions meant that for the longest time, companies had to turn away potential investors. Nowadays, blockchain technology enables businesses to easily automate these procedures via smart contracts.

Smart Contracts

Smart Contracts feature preprogrammed protocols that execute when they receive a certain amount of cryptocurrency sent to their address. These contracts live on the blockchain and enable remarkable functionality. For example, in the case of fundraising, a smart contract can automate processes such as the approval of investors and the distribution of funds.

Blockchain Technology Today

You can expect to see further expansion of the blockchain sector in the coming months as more governments and institutions explore its benefits. For now, the blockchain revolution is well underway.

30+ Reasons Why Cryptocurrencies Are Worthless

1)It is possible to change the code through a miner vote or a fork and change the total supply or anything. DASH did it : they reduced the total supply from 84M to 18.9M a few years ago. They could also increase it to 999 Trillions if they wanted to so that millions of DASH are mined every week.

2)You can also fork bitcoin anytime , start over from 0 and claim it's the real bitcoin. (BCH , BSV , BTG , LTC , BCD etc)

3)Why would you pay $10,000 for a digital collectible unit called BTC when you can use BCH or TRX or LTC .. you name it. They work just as fine and cost less. There is no rarity like in gold.

4)Think of any amount you hold in ethereum as a gift card to use smart contracts on the ETH blockchain. Ridiculous. You’d rather hold a wal mart gift card or even simply cash.

5)Private keys may be bruteforced as we speak. Quintillions entries a second. When they’ll have enough bitcoins under control , they could move them all at once instantly.(At least 45,000 ETH have been stolen this way for now through ethereum bandit)SHA 256 is too old , bitcoin is 10 years old , it is not secure enough , quantum computing could potentially break it.

6)And that’s if people don’t find a way to create an infinite amount of coins to sell on exchanges.. it happened with monero , stellar , bitcoin , zcash , zcoin , eos , etc..

proofs :

“Bitcoin , Coindesk : “The Latest Bitcoin Bug Was So Bad, Developers Kept Its Full Details a Secret”an attacker could have actually used it to create new Bitcoin — above the 21 million hard-cap of coin creation — thereby inflating the supply and devaluing current bitcoins.”

Stellar : “Stellar Inflation: Glitch Leads to 2.25 Billion Extra XLM Printed”

Monero : “A bug in the Monero (XMR) wallet software that could enable fake deposits to exchanges has been recently brought to public attention through a Medium post”

Zcoin : Forged coins were created, but not exceeding 1% of the circulating supply. We will release further details on exact numbers when Sigma is released.

EOS : “Hackers Forge Billion EOS Coins to Steal Real Crypto From DEX “

Zcash : “Zcash Team Reveals It Fixed a Catastrophic Coin Counterfeiting Bug” etc..

7)Segwit , and especially Lightning network is a very complex technology and it will inevitably have flaws , bugs , it will be exploited and people will lose money. That alone can cause bitcoin to drop very low levels.

8)Then miners may be losing millions so they will stop mining , blocks may be so slow , almost no transaction will come though , and bitcoin may not have enough time to reach the next difficulty adjustement. This is reffered to as a death spiral. Then every crypto even those with no mining involved may crash hard.

9)Many crypto wallets are unsafe and have already caused people to lose all their investment , including the infamous “parity wallet”.

10)It is NOT trustless. you have to trust the wallet you’re using is not just generating an address controlled by the developper , you have to trust the node the wallet connects to is an honest node , you have to trust a Rogue state or organization with enough computing power will not 51% attack the network. etc..

11)Bitcoin is NOT deflationary. Bitcoins are created every blocks (roughly every 10 minutes) and you wil be dead by the time we reach the 21 million current hard cap.

12)Bitcoin price may artificially be inflated by Tether.

13)It’s an energy waste , an environmental catastrophy.

14)The only usecases are money laundering , tax evasion , gambling , buying on the dark net , evading sanctions and speculation.

15)Governments will ban it if it gets too big , and they have a big incentive to do so , not only for the obscure usecases but also because it threatens the stability of sovereign currencies. Trump could kill bitcoin with one tweet , force fiat exchanges to cease activity.

16)Most cryptos are scams , the rest are just crazy speculative casino investments.

17)It is pyramidal : early adopters intend to profit massively while last comers get crushed. That's not how money works. The overwhelming majority of crypto holders are buying it because they think they will be able to sell it to a higher price later. Money is supposed to be rather stable. That's why the best cryptocurrencies are USDT USDC etc..

18)The very few stores accepting bitcoin always have the real price in the local currency , not in bitcoin. And prices like 0.00456329 BTC are ridiculous !

19)About famous brokers listing bitcoin : they have to meet the demand in order to make money , it doesn't mean they approve it , some even short it (see interactive broker's CEO opinion on bitcoin)

20)People say cash is backed by nothing and losing value slowly , and yes it is very flawed , but there is a whole nation behind it , it's accepted everywhere , you can buy more things with it.

21)Everybody in crypto thinks that there will be a new bullrun and that then , they will sell. But because everybody thinks it will happen , it might not happen. The truth is past performance doesn’t indicate future performance and it is absolutely not guaranteed that there will ever be another bullrun. The markets are unpredictable.

22)Also BTC went from about $0.003 to the price it is today , so don’t think it’s cheap now.

23)There is no recourse if you’re scammed/hacked/made a mistake in the address etc. No chargebacks. But it might be possible to do a rollback (blockchain reorganization) to reverse some transactions. BSV did it.

24)In case of a financial crisis , the speculative assets would crash the most and bitcoin is far from being a non speculative safe heaven ; and governments might ban it to prevent fiat inflation to worsen.

25) Having to write down the private key somewhere or memorize it is a security flaw ! It’s insane to think a system like this will gain mass adoption.

26) The argument saying governments can not ban it because it is decentralized (like they banned drugs) doesn’t work for cryptos. First , drugs are much harder to find and much more expensive and unsafe because of the ban , and people are willing to take the risk because they like it. But if crypto is banned , value will drop too much , and if you can’t sell it for fiat without risking jail , goodluck to find a buyer. Fiat exchanges could close. Banks could terminate every crypto related bank account. And maybe then the mining death spiral would happen and kill all cryptos.

27) Crypto doesn’t exist. It’s like buying air. It’s just virtual collectibles generated by a code. Faguzzi, fugazzi, it’s a whazzie, it’s a whoozie.. it’s a.. fairy dust. It doesn’t exist. It’s never landed. It’s no matter, it’s not on the elemental chart. It… it’s not fucking real!

28) Most brilliant guys have come out and said Bitcoin was a scam or worthless. Including Bill Gates , Warren Buffet , The Wolf Of Wall Street…

29) Inflation is necessary for POW , BTC code will have to be changed to bypass the 21M cap or mining will die ! If BTC code is not changed to allow for miners to be paid reasonably , they will cease mining when the bitcoin block reward gets too low.Even monero understood it ,the code will have to be changed to allow for an infinite bitcoin supply (devaluating all current bitcoins) or the hash will decrease and the security of bitcoin will decrease dramatically and be 51% attacked

30) Don’t mix up blockchain and cryptos. Even blockchain is overrated. But when you hear this or that company is going blockchain , it doesn’t mean they support cryptocurrencies.

31) Craig Wright had a bitcoin mining company with Dave Kleinman (he died) and on january 1 2020 he claims he will be able to access the 1.1M BTC/BCH/BTG from the mining trust. He may or may not dump them on the market , he also said BTC had a fatal flaw and that by 2019 there will be no more BTC.

32) Hacks in cryptos are very common and usually massive. Billions of dollars in crypto have been stolen in the last 6 years. In may 2019 Binance was hacked and lost 7,000 BTC (and it’s far from being the biggest crypto hack).

33) Bitcoin was first. It's an ancient technology. Newer blockchains have privacy, smart contracts, distributed apps and more.Bitcoin is our future? Was the Model T the future of the automobile? (John Mc Afee)

34) IOTA investiguating stolen funds on mainnet. IOTA shuts down the whole network to deal with trinity wallet attack.

30+ Reasons Why Cryptocurrencies Are Worthless

1)It is possible to change the code through a miner vote or a fork and change the total supply or anything. DASH did it : they reduced the total supply from 84M to 18.9M a few years ago. They could also increase it to 999 Trillions if they wanted to so that millions of DASH are mined every week.

2)You can also fork bitcoin anytime , start over from 0 and claim it's the real bitcoin. (BCH , BSV , BTG , LTC , BCD etc)

3)Why would you pay $10,000 for a digital collectible unit called BTC when you can use BCH or TRX or LTC .. you name it. They work just as fine and cost less. There is no rarity like in gold.

4)Think of any amount you hold in ethereum as a gift card to use smart contracts on the ETH blockchain. Ridiculous. You’d rather hold a wal mart gift card or even simply cash.

5)Private keys may be bruteforced as we speak. Quintillions entries a second. When they’ll have enough bitcoins under control , they could move them all at once instantly.(At least 45,000 ETH have been stolen this way for now through ethereum bandit)SHA 256 is too old , bitcoin is 10 years old , it is not secure enough , quantum computing could potentially break it.

6)And that’s if people don’t find a way to create an infinite amount of coins to sell on exchanges.. it happened with monero , stellar , bitcoin , zcash , zcoin , eos , etc..

proofs :

“Bitcoin , Coindesk : “The Latest Bitcoin Bug Was So Bad, Developers Kept Its Full Details a Secret”an attacker could have actually used it to create new Bitcoin — above the 21 million hard-cap of coin creation — thereby inflating the supply and devaluing current bitcoins.”

Stellar : “Stellar Inflation: Glitch Leads to 2.25 Billion Extra XLM Printed”

Monero : “A bug in the Monero (XMR) wallet software that could enable fake deposits to exchanges has been recently brought to public attention through a Medium post”

Zcoin : Forged coins were created, but not exceeding 1% of the circulating supply. We will release further details on exact numbers when Sigma is released.

EOS : “Hackers Forge Billion EOS Coins to Steal Real Crypto From DEX “

Zcash : “Zcash Team Reveals It Fixed a Catastrophic Coin Counterfeiting Bug” etc..

7)Segwit , and especially Lightning network is a very complex technology and it will inevitably have flaws , bugs , it will be exploited and people will lose money. That alone can cause bitcoin to drop very low levels.

8)Then miners may be losing millions so they will stop mining , blocks may be so slow , almost no transaction will come though , and bitcoin may not have enough time to reach the next difficulty adjustement. This is reffered to as a death spiral. Then every crypto even those with no mining involved may crash hard.

9)Many crypto wallets are unsafe and have already caused people to lose all their investment , including the infamous “parity wallet”.

10)It is NOT trustless. you have to trust the wallet you’re using is not just generating an address controlled by the developper , you have to trust the node the wallet connects to is an honest node , you have to trust a Rogue state or organization with enough computing power will not 51% attack the network. etc..

11)Bitcoin is NOT deflationary. Bitcoins are created every blocks (roughly every 10 minutes) and you wil be dead by the time we reach the 21 million current hard cap.

12)Bitcoin price may artificially be inflated by Tether.

13)It’s an energy waste , an environmental catastrophy.

14)The only usecases are money laundering , tax evasion , gambling , buying on the dark net , evading sanctions and speculation.

15)Governments will ban it if it gets too big , and they have a big incentive to do so , not only for the obscure usecases but also because it threatens the stability of sovereign currencies. Trump could kill bitcoin with one tweet , force fiat exchanges to cease activity.

16)Most cryptos are scams , the rest are just crazy speculative casino investments.

17)It is pyramidal : early adopters intend to profit massively while last comers get crushed. That's not how money works. The overwhelming majority of crypto holders are buying it because they think they will be able to sell it to a higher price later. Money is supposed to be rather stable.

18)The very few stores accepting bitcoin always have the real price in the local currency , not in bitcoin. And prices like 0.00456329 BTC are ridiculous !

19)About famous brokers listing bitcoin : they have to meet the demand in order to make money , it doesn't mean they approve it , some even short it (see interactive broker's CEO opinion on bitcoin)

20)People say cash is backed by nothing and losing value slowly , and yes it is very flawed , but there is a whole nation behind it , it's accepted everywhere , you can buy more things with it.

21)Everybody in crypto thinks that there will be a new bullrun and that then , they will sell. But because everybody thinks it will happen , it might not happen. The truth is past performance doesn’t indicate future performance and it is absolutely not guaranteed that there will ever be another bullrun. The markets are unpredictable.

22)Also BTC went from about $0.003 to the price it is today , so don’t think it’s cheap now.

23)There is no recourse if you’re scammed/hacked/made a mistake in the address etc. No chargebacks. But it might be possible to do a rollback (blockchain reorganization) to reverse some transactions. BSV did it.

24)In case of a financial crisis , the speculative assets would crash the most and bitcoin is far from being a non speculative safe heaven ; and governments might ban it to prevent fiat inflation to worsen.

25) Having to write down the private key somewhere or memorize it is a security flaw ! It’s insane to think a system like this will gain mass adoption.

26) The argument saying governments can not ban it because it is decentralized (like they banned drugs) doesn’t work for cryptos. First , drugs are much harder to find and much more expensive and unsafe because of the ban , and people are willing to take the risk because they like it. But if crypto is banned , value will drop too much , and if you can’t sell it for fiat without risking jail , goodluck to find a buyer. Fiat exchanges could close. Banks could terminate every crypto related bank account. And maybe then the mining death spiral would happen and kill all cryptos.

27) Crypto doesn’t exist. It’s like buying air. It’s just virtual collectibles generated by a code. Faguzzi, fugazzi, it’s a whazzie, it’s a whoozie.. it’s a.. fairy dust. It doesn’t exist. It’s never landed. It’s no matter, it’s not on the elemental chart. It… it’s not fucking real!

28) Most brilliant guys have come out and said Bitcoin was a scam or worthless. Including Bill Gates , Warren Buffet , The Wolf Of Wall Street…

29) Inflation is necessary for POW , BTC code will have to be changed to bypass the 21M cap or mining will die ! If BTC code is not changed to allow for miners to be paid reasonably , they will cease mining when the bitcoin block reward gets too low.Even monero understood it ,the code will have to be changed to allow for an infinite bitcoin supply (devaluating all current bitcoins) or the hash will decrease and the security of bitcoin will decrease dramatically and be 51% attacked

30) Don’t mix up blockchain and cryptos. Even blockchain is overrated. But when you hear this or that company is going blockchain , it doesn’t mean they support cryptocurrencies.

31) Craig Wright had a bitcoin mining company with Dave Kleinman (he died) and on january 1 2020 he claims he will be able to access the 1.1M BTC/BCH/BTG from the mining trust. He may or may not dump them on the market , he also said BTC had a fatal flaw and that by 2019 there will be no more BTC.

32) Hacks in cryptos are very common and usually massive. Billions of dollars in crypto have been stolen in the last 6 years. In may 2019 Binance was hacked and lost 7,000 BTC (and it’s far from being the biggest crypto hack).

33) Bitcoin was first. It's an ancient technology. Newer blockchains have privacy, smart contracts, distributed apps and more.Bitcoin is our future? Was the Model T the future of the automobile? (John Mc Afee)

Mining and Dogecoin - Some FAQs

Hey shibes,
I see a lot of posts about mining lately and questions about the core wallet and how to mine with it, so here are some facts!
Feel free to add information to that thread or correct me if I did any mistake.

You downloaded the core wallet

Great! After a decade it probably synced and now you are wondering how to get coins? Bad news: You don't get coins by running your wallet, even running it as a full node. Check what a full node is here.
Maybe you thought so, because you saw a very old screenshot of a wallet, like this (Version 1.2). This version had a "Dig" tab where you can enter your mining configuration. The current version doesn't have this anymore, probably because it doesn't make sense anymore.

You downloaded a GPU/CPU miner

Nice! You did it, even your antivirus system probably went postal and you started covering all your webcams... But here is the bad news again: Since people are using ASIC miners, you just can't compete with your CPU hardware anymore. Even with your more advanced GPU you will have a hard time. The hashrate is too high for a desktop PC to compete with them. The blocks should be mined every 1 minute (or so) and that's causing the difficulty to go up - and we are out... So definitly check what is your hashrate while you are mining, you would need about 1.5 MH/s to make 1 Doge in 24 hours!

Mining Doge

Let us start with a quote:
"Dogecoin Core 1.8 introduces AuxPoW from block 371,337. AuxPoW is a technology which enables miners to submit work done while mining other coins, as work on the Dogecoin block chain."
- langerhans
What does this mean? You could waste your hashrate only on the Dogecoin chain, probably find never a block, but when, you only receive about 10.000 Dogecoins, currently worth about $25. Or you could apply your hashrate to LTC and Doge (and probably even more) at the same time. Your change of solving the block (finding the nonce) is your hashrate divided by the hashrat in sum - and this is about the same for Doge and LTC. This means you will always want to submit your work to all chains available!

Mining solo versus pool

So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or $2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.

Buying an ASIC

You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per $ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...

Making profit

You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.

Cloud Mining

Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc.
Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you $54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same.
Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.

Alternative coins

Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!

Folding at Home (Doge)

Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much.
Thanks for reading

Will my recovery phrase still work 100 years+ from now?

Assuming the Bitcoin network exists 100 years from now, would my future grand-children be able to recover my Bitcoin if they found my seed phrase that I created in 2018?
Or is it possible that by then the technology will have evolved (such as migrating to a stronger encryption protocol, perhaps) to such an extent that recovery keys from 100 years ago are no longer compatible?

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

Could anyone reverse engineer private keys from public ones? I know it's meant to be impossible, but...

Surely whatever the future brings, it will bring UNTOLD supercomputing power. Computers are already that much better at cryptographic problem-solving, thanks to Bitcoin itself.
SHA256 hash may be high-grade for its time, but am I correct in saying that all you need to beat it is more raw computing power? A large amount, but... no higher degree of complexity. Just power and time.
Some claims have been made that private keys have already been reverse engineered from public ones.
It does seem implausible, but presumably anybody who accomplished this task would end bitcoin and destroy a 100 billion dollar market. Probably a few teams working on it right now.
Presumably Satoshi knows precisely how the hashing function works. Wouldn't that help him to reverse engineer keys? If not, why not?

Litecoin is created by Charlie Lee, an ex-Google employee, to had the vision to create something which is lighter and cheaper than Bitcoin, hence the name. On October 7, 2011, Litecoin was released by an open-source client on GitHub. Litecoin is formed from Bitcoin, with similar features and characteristics. So, it is the fork of the Bitcoin. Litecoin is an improved version of Bitcoin will lesser brand awareness.
Litecoin is one of the most under-valued and grounded cryptocurrencies in the world, being in existence for seven years since 2011. Litecoin is more accessible to the people than Bitcoin, hence known as “silver” of crypto world and Bitcoin referred to as “gold” of the crypto world.
Litecoin is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. Litecoin is an open source, global payment network that is fully decentralized without any central authorities.
Mathematics secures the network and empowers individuals to control their own finances. Litecoin features faster transaction confirmation times and improved storage efficiency than the leading math-based currency. With substantial industry support, trade volume and liquidity, Litecoin is a proven medium of commerce complementary to Bitcoin.
Some of the differences between Litecoin and Bitcoin are:
Is Litecoin a Good Investment?
Choosing which cryptocurrency to invest in can be a headache, especially as the markets change so quickly. One of the most successful coins of 2017 was Litecoin, which increased its value by more than 5000% in just 12 months.
Litecoin was originally created in 2011 after it forked an updated version of the Bitcoin client. This is why it’s sometimes called Bitcoin-Lite! Don’t worry, this will all be explained!
In this complete guide, we will tell you everything you need to know about Litecoin. This will begin with some background information on what Litecoin is, and whether we think it is a good or bad investment. We are also going to show you how to buy Litecoin, and which wallet you should store it in.

next trezor release should use a SE

This is taken from the coldcard site:
We find it a quite scary that some Bitcoin wallets trust the main microprocessor with their most valuable secrets. Instead, Coldcard uses a Secure Element to protect your Bitcoin.
Specifically, the Coldcard (Mk3) uses Microchip's ATECC608A to store the critical master secret: the 24-word seed phrase for your BIP32/BIP39 wallet.
This little chip is very powerful. Communication is controlled by complex challenges and SHA-256 responses which prevent replay and eavesdropping. The secure element enforces cryptographically, that the attacker must know the PIN to access the secrets. An attacker cannot brute-force combinations or replay a previous login sequence. This remains true even if they removed the chip from the board or fully-replaced the firmware in the main microprocessor. In fact, even with the secure element removed from the system, and all the secrets of the main micro fully-known, the attacher would still only get 13 tries before the secure element bricks itself! (Don't worry, this counter is reset every time you login correctly.)
Even if there was some critical security bug in the secure element that completely exposed the secrets it holds, your Bitcoin would still be safe, because we encrypt the contents of the secure element with a one-time pad known only to the main micro.
More details are available in this white paper and the complete source code is available.
https://coldcardwallet.com/
Also please don't try to apply the 'open source is more secure principal'. This is a fallacy when applied to hardware. It only works in software because you can verify it a product was built using that software by building it yourself this does not apply to hardware.
I already bought the MK3 but i have other assets that are only supported by trezor and I am reluctant to switch to a ledger. However if trezor is adamant in using 'Open source hardware' whatever the fuck that means I will be forced to switch.
Also are passphrase even supported for ethereum dapps. Trezor integrates with exodus and MEW but they never prompt for a passphrase?
