4841  Other / Beginners & Help / Re: Is Coinbase noncustododial wallet recommendable? on: April 25, 2022, 03:38:00 AM
Another concern people should always have when it comes to light wallets (which in this case is at the bottom of the list due to more serious issues) is the server they are using. Doubly so if they are closed source. In this case you may have control over your keys but you may not be the only one with access, the company could also have all your keys!

The only case I could see Coinbase being useful is their custodial wallet (the account you create on their website) for the absolute beginners who have a hard time grasping how bitcoin works. They can give up their privacy, control, security,... for the convenience that Coinbase provides and the ability to easily buy bitcoin. They can always learn more in the future and move away.
But if someone has gotten over that hump, there is no reason to use anything that Coinbase creates! Including what they claim to be non-custodial.
4842  Bitcoin / Project Development / Re: Are dices for generating seed words fair? on: April 25, 2022, 03:18:24 AM
Here is a complementary idea: mix the result
Extending the proposal: Use the hash function thousands of times. Not only you ensure that a dice bias isn't enough to betray you, but you also make it much harder for an attacker to find your entropy.

For example, let's assume that one of the dices you use has a 50% chance of returning the number 6. Let's also assume that your RNG is weakened. Now it's much easier for an attacker to hash the dices' entropy mixed with the semipredictable generated number. But, if you use the hash function twice, you've just made it two times more difficult. Do it a few million times and you've made it realistically impossible.

I can't believe how paranoid, schizophrenic and miserable I've become since I made an account here.  Tongue
That sounds like overkill to me because the dice has to be really broken to create a bias big enough to make the end result weak, same with the RNG. But hey it never hurts to add more cost to your process as long as you can endure the extra time it needs.
In that case I'd suggest using an expensive KDF such as scrypt to derive the key instead of increasing the number of hashes you compute. You can change scrypt parameters to use a lot of memory to maximize the expense.
4843  Bitcoin / Bitcoin Technical Support / Re: redeem BRD gifts : decoding breadwallet URLs (BTC gift, base64 -> base58 -> ?) on: April 25, 2022, 03:00:15 AM
P.S. The address @Btcspot (17yWT...) posted is ignoring the mistake in OP's string and just takes the 32 byte key out of the decoded result.
But this address has a transaction history - received 0.00098806 BTC and then sent it out again a few hours later. It would be incredibly unlikely that wrongly decoding the string OP provided would result in a valid and already used private key.

So it seems all OP has to do is decode the base64 string to hex as he has done, strip off the first and last bytes, and then convert the resulting 64 characters to a WIF key to import in to his wallet.
Yes, this was the reason why I guessed that the initial Base64 string is modified and also considering that the code doesn't seem to do such a thing, there is a good chance that what OP had was actually some sort of a puzzle that could have been solved this way.

He certainly doesn't put his customer's interests above his own, but by refunding millions of dollars worth of BTC, he has placed himself in a position where people will gladly return and use his exchange instead of something else. That doesn't have to mean anything, but still. 
You have very good points but Binance could pay its users back because they didn't really leave the exchange behind due to lack of better alternatives and since they weren't still enforcing KYC like they do today. So they could continue making money and paid them back slowly.
This may not be repeated if such hacks happen again, users may leave the exchange behind as it would be another incentive for them to seek an alternative (KYC enforcement being the first, shutting down accounts or blocking deposits for "taint" would be next).

IMO, the only way to reduce the electricity consumed below the above is to switch from PoW to PoS.
I noted above that it remains my belief that PoW remains superior to PoS.
You are contradicting yourself here.
Even if we agree that PoW should be replaced, the replacement is never going to be a weaker algorithm such as PoS that has many flaws. You see when you are trying to solve one problem you should do it in a way that it doesn't introduce 50 new issues.
4846  Bitcoin / Bitcoin Discussion / Re: I lost my bitcoin on: April 24, 2022, 07:59:23 AM
I've got a feeling that you never owned any bitcoin to begin with, considering you claim that you have met a completely random person on a "hookup app" and they created everything for you including your bitcoin wallet!
You may only had a watch-only address that contained some bitcoins that didn't belong to you (you didn't have the key to from the start).
4847  Bitcoin / Bitcoin Discussion / Re: Where have you saved your bitcoin keys? on: April 24, 2022, 05:07:16 AM
It is wrong to only use one option if you ask me. I personally prefer multiple options and multiple backups.
For example you could have a hot wallet on your desktop or your phone containing a small amount of bitcoin that you may need quick access to whenever you want to spend some bitcoin.
Then you also want a secure storage to keep the bulk of your bitcoins which is when cold storage comes in. For backup you could use paper wallets alongside your digital storage (burnt on a disk or a USB stick or old computer,... all airgap).
If you rely on one solution (digital storage for example) you could end up losing access (e.g. data decay in this case).

satoshi who stated it that he has saved it and buried it
Where did Satoshi say this?
4848  Bitcoin / Bitcoin Discussion / Re: “A single bitcoin transaction could power the average US household for a month" on: April 24, 2022, 04:41:43 AM
This is one of the oldest and most used strategies both invented and mainly used in United States. The bogeyman strategy. If they want sheeple to fear something, they have to build a big bogeyman out of it and to do that they need to convince them somehow specially if there is no truth to that. The main part of this strategy is telling the biggest lie they can.

They tried telling sheeple bitcoin is a Ponzi scheme, too risky to buy, is gonna die, China (the other bogeyman strategy) controls bitcoin, is used for illegal shit, ... and all of them failed.
Now they are trying a new lie about the energy consumption and it is a good one since a lot of places including US itself are having a lot of energy related problems (they either have problem keeping the lights on or the prices are soaring or both!). They also can't just tell you "bitcoin is using a lot of energy" because sheeple won't feel it to their bones, they have to tell them "a single bitcoin tx uses more electricity than single one of you the sheeple".
4849  Economy / Speculation / Re: Bitcoin dominance is key on: April 24, 2022, 04:21:18 AM
Bitcoin dominance is a very important metric and we all should know it, why!
Bitcoin dominance and if you understand it, really shows how strong Bitcoin is performing!
First of all the term "dominance" is wrong, it is "market cap ratio" and it is the most useless metric that has ever existed in any market. Even if you are making the correct conclusion based on it!
You have a good point about solo bitcoin being compared against total of thousands of shitcoins though.

The big fundamental flaw in market cap and their ratio is that you can not control what "supply" value is the correct value to use and less importantly what "price" is actually the correct price.
Take the biggest shitcoin of all times ethereum for example. It has 72 million premine so it is not part of its supply. Same with BNB, XRP, etc. they all have "fake circulating supply" and when you remove that their market cap drops significantly.

The same problem happens to price but mostly about new shitcoins. In simple terms you can create a new token for virtually no cost and then sell it for a billion dollar to yourself (you don't have to pay anything just say the transaction took place or put the money from your left pocket into your right pocket) and that means you shitcoin's market cap is $1 billion * whatever supply it has!

Bitcoin has been around for a very long time and after a few years, more coins have arrived to overtake Bitcoin. But so far, not a single coin achieved an overtake.
That's not true, I believe it was 2017 when a shitcoin nobody had ever heard of surpassed bitcoin's marketcap because someone did what I explained above Cheesy
4850  Other / Beginners & Help / Re: Newbies Hodle and profit in a Pumps and Dumps market. on: April 24, 2022, 03:55:28 AM
The main problem I see here is that you are assuming that the price of a pump and dump shitcoin you are bag holding is going to move in your favor. That is not realistic specially because of the type of the coin. In other words if you are bag holding something at $2 the most probably outcome is that it stays there and slowly loses value ($2 > $1.99 > $1.98) and it encourages more bag holding because you can't just sell at a small loss while continue losing money little by little.

The better strategy in my opinion is to not bag hold such shitcoins in first place but only buy them when you see the price is pumping from $2. This way you may think you are losing on a little bit of profit but you are actually reducing the risk you are taking and tremendously reducing the losses you could have experienced. You just buy at something like $2.2 then dump at $2.9.
The best thing about this strategy is that your money is not locked up in some shitcoin forever wishing it would pump so that you can sell it. You always have your liquidity ready and can jump from shitcoin A to shitcoin B all the way to shitcoin Z and make small profit from all of them consistently.
Obviously this is a lot of work but making money is never easy!
4851  Other / Beginners & Help / Re: 6 real-life lessons I learnt from Bitcoin (No 6 will amaze you👇) on: April 24, 2022, 03:46:40 AM
2. WHAT GOES UP MUST SURELY COME DOWN:
This is not quite correct.
Going up alone does not guarantee the next step (coming down). If that were true then bitcoin price should have never gone past the $0.01 price ever because by this logic whenever it went up it should have come down again!
The correct statement is depending on why and how it went up it could come back down. For example a shitcoin that is pumped is going up and that guarantees 100% that the dump comes and price of that pumped shitcoin comes down.
But for another example last year bitcoin went from $10k to $30k and it never went back down below it.

Quote
Because I could remember far back when sending money to family and friends across borders was seen as something impossible or expensive, through the use of middlemen who charges high, but bitcoin came and saved us the stress and time breaking the barrier of location.
I wonder how you deal with exchange rates and the extra fees they entail.

4. THE REJECTED CAN BE SOMEDAY VALUED:
So it's always good to value every little opportunity that comes your way because nobody knows tomorrow.
As long as this "opportunity" is real and not some fake shitcoin advertisement telling you to buy it because it is "bitcoin 2.0".

When we are talking about Binance, the past hacking incidents have proven that this exchange is the best place where you can get hacked. It seems very weird saying that without further explanation. When Cryptopia was hacked, that was it, they were done. Binance was hacked a few years ago and their customers lost over 7.000 BTC, worth $40 million at the time. Those losses were refunded to the affected users and Binance is still going strong and belongs to the top #3 CEXes in the world.   
That's true but the problem is that you can never predict the future what is happening in their business. For example mtgox wasn't #3 CEX, it was #1 and didn't have silly 10%-20% of total daily trading volume it had more than 85% of the total trading volume among all existing CEXes and yet we saw what happened to it in the end.
4853  Bitcoin / Bitcoin Discussion / Re: Honduras SEZ accepting Bitcoin as legal tender. What could be the benifits? on: April 23, 2022, 05:11:07 AM
It argues that bitcoin can reduce poverty.
I don't see how bitcoin could do that, at least not directly.
The only indirect effect I could see, and that's just a possibility, is if bitcoin could help the economy of these countries, attract foreign investors, etc. and the improvement of economy could help reduce the poverty.
Otherwise if you think poor people are going to invest in bitcoin and become rich, that's not going to happen.

What could be the other possible benifits of legalizing bitcoin
It's starting a good movement in my opinion. We all know that bitcoin is decentralized and censorship resistant so it doesn't need anyone's approval (eg. legalization) to work but also we can't deny the fact that legalization of it (specially as legal tender not an asset or silly things like that) tremendously help bitcoin adoption.

P.S. Google tells me SEZ is a special economic zone in Honduras so it doesn't look like this is a country wide legalization. Which makes it a smaller version of El Salvador case.
4854  Bitcoin / Bitcoin Discussion / Re: [GUIDE] How to send BTC for cheap! (And stop paying $25 for withdrawals) on: April 23, 2022, 05:04:19 AM
I AGREE. Literally, all of those options are marketed as the "cheaper" bitcoin options to withdraw from binance.

It's like if somehow, binance wanted to hoard bitcoin by making ridiculous withdrawal fees.
Mainly everything that centralized exchanges like Binance do is to make money. The fact that they advertise shitcoins as "cheaper options to withdraw bitcoin" is because they want to advertise their own shitcoin called BNB. In fact there are a lot of things they encourage people to do using BNB which is the only reason this shitcoin has been pumped. Who makes the most profit when it pumps? Obviously Binance since they create it out of thin air and sell it to newbies.
4855  Bitcoin / Bitcoin Discussion / Re: Any unexpected incidents - Bitcoin on: April 23, 2022, 03:30:46 AM
However slowly bitcoin is getting displayed here and there without reason.
I wouldn't say it is completely without reason.
Bitcoin is used by many travel agencies, not to mention that it is the best currency to use by travelers since it is the only truly global currency that has the same value everywhere in the world (almost everywhere since during short periods price could go up in certain countries like what happened in India a couple of years ago).
At the end of the day bitcoin adoption is constantly growing.

@pooya87: 19 tons/day is nothing for a 500+ MW plant. It's comparable with the consumption of a single aircraft. A Boeing 747 consumes 10-11 tonnes per hour!
You can't really begin to compare the highly efficient and expensive fuel used in an airplane like Boeing 747 with the lowest quality dirt cheap gasoil with a lot of impurities used here. Not to mention that the plane would emit CO2 while this is emitting SO2 which is worse.
4857  Other / Beginners & Help / Re: spend twice more Bitcoins while waiting the block to be verified? on: April 23, 2022, 02:51:48 AM
Now, in a situation where I want to buy a grocery from the local shop for 0.0001 Bitcoin, should I wait 10 minutes (maybe 5) so that the seller makes sure that the transaction is valid?
When you go to the grocery store and pay with your credit card for example, do you wait for 6 months for the transaction to be confirmed?

What if I will spend twice more Bitcoins then I have in my wallet while waiting the block to be completed? Thanks.
What if you pulled a credit card fraud or reversed the payment before 6 months?

You see bitcoin is just a payment system with well known characteristics that is actually so much better than any other payment system. But just because it is new and decentralized people think it should be treated differently until you get used to it.
The fact is that scamming using any other payment method is so much easier than scamming using bitcoin payment in most cases. For example if you pay the store with a decent amount of fee and not use RBF in your transaction the confidence in such a transaction is high and chances of scam is so much lower. The store's node could also be set up in a way to monitor the mempool and analyze the payment transaction for confidence.
4858  Other / Beginners & Help / Re: We are not safe with centralize exchanges, know this and get peace on: April 23, 2022, 02:35:58 AM
Anything you see centralization, there are pretty much the same risks involved. It doesn't matter if it is an exchange or any other service like that. They always comply with the governments and won't need that much pressure either, as long as the simplest request comes they jump to obey. As I said this is not just for CEX either, we saw how the privacy oriented tool called Wasabi wallet obeyed and started censoring transactions in their CoinJoin coordinator!

Even there's no proof whether the story above were true or not,
They share it with all governments of all countries that demanded it because they don't want to be shut down or lose any portion of the market.

I mentioned twice that I’m not talking about the coinbase.com wallet. I’m talking about their new wallet called Coinbase Wallet which it gives you the 12 seed phrase.
Is it open source because I couldn't find any source code (although I only looked a little). If you can't see the source code and can not compile it yourself then you should avoid such wallets and stick to other wallets that are open source such as Electrum.
4860  Bitcoin / Development & Technical Discussion / Re: How to reduce energy consumption and eliminate wasted work on: April 22, 2022, 11:45:06 AM
New users wouldn't really even need the Bitcoin software.  They could download a miner, create an account on mtgox or mybitcoin, enter their deposit address into the miner and point it at anyone's pool server.  When the miner says it found something, a while later a few coins show up in their account.
Lol. This didn't age well.
You shouldn't read anybody's posts out of context least of which Satoshi's.
In short the discussion there is about whether the miners connecting to a pool need to run their own software (whether the original or modified or whatever else).
@ribuck explains why in a mining pool (the first of) only the pool runs the client and there is no need for others (the miners connecting to it) run their own Bitcoin clients. @grondilu is arguing that others can run their own [modified] software, connect to the pool and both mine the block to receive the block reward and receive the pool's reward at the same time.
To this Satoshi states that it is not possible due to the way pool is designed and continues to say users don't even have to run the software to use a pool, they can use a shitty centralized exchange to get an address and receive the funds. He isn't saying they should!
