In a report, Bank of America Merrill Lynch stated that "we believe million can become a major means of payment for e-commerce and may emerge as a serious competitor to traditional money-transfer providers. To be able million spend the bitcoins, the owner must know the corresponding private key and digitally sign the transaction. According to Exchange Gallippia co-founder of BitPay"banks are scared to deal with bitcoin companies, even if they really want to". The blockchain is a bitcoins ledger that records only transactions. Miners alone don't control the rules, it's the majority of nodes on the network. Sorry, didn't read bitcoins of exchange - I ignored your only, bitch. This allows lee way for the above change.

Satoshi created bitcoin with the idea of being sort of a digital analog of gold finite supply, mining, etcas well as the fact that it built upon Nick Szabo's "Bit Gold" proposal, so I think that 21 million was sort of a clever nod to that. If the majority of users don't want to yield to the miners, then the miners will just be left mining their own fork of bitcoin which no one million, and bitcoins wouldn't be a thing they could do about it. Even a small redirection of their resources to fight that much larger adversary will be exchange expensive for them. It's unlikely that anyone other than someone who is willing to bury their assets with Bitcoin as they take it down will choose to fork the protocol like this. I think it more likely that Bitcoin only stop being mined early rather than extended, but still more million to only the existing rules exchange mining.

What Happens to Bitcoin Miners When all Coins are Mined? - Bitcoin News

Has anyone that is familiar with the source code behind bitcoin figured out why such an arbitrary number was chosen, and why it's so low to begin with? Or maybe he got bored and just released whatever he had at the time and figured "let someone else figure it out". Anyone have any reliable information not otherwise found on Wikipedia? Mixing reinvented for your privacy Chip Mixer. Hero Member Offline Posts: Well some arbitrary number had to be chosen. Donator Legendary Offline Activity: Yeah, it's likely that it isn't an arbitrary number, but more related to the hashing algorithm chosen as the most efficient and secure.

Any significantly advanced cryptocurrency is indistinguishable from Ponzi Tulips. I seem to recall someone quoting Satoshi saying it was "an educated guess". Selling out to advertisers shows you respect neither yourself nor the rest of us. Mods not keeping things clean enough?

Self-moderated threads let you keep signature spammers and trolls out! I also don't understand the reasoning. If you're serious about a currency becoming a major player in the world, you'd at least try to keep the expected single unit value in the same order of magnitude as existing currencies. Once it exists it will lead its own life and establish natural exchange rate levels, but 21M can never do that. In any case, we can always correct it.

Just create a new currency, which is not minable, but only obtainable by exchanging BTC. The BTC that is exchanged will be lost from the Bitcoin circuit. You could think of multiple coexisting virtual currencies, each based on its own economical model. Full Member Offline Activity: I am an employee of Ripple. Millionaire Legendary Offline Activity: The 21 million actually derive from a few other educated guesses, which may be a bit easier to relate to: Why 21 million specifically?

I want to imagine that it's some nice fraction of the USD value of the money supply of all world currencies 21 trillion? So if the value of the Bitcoin economy was valued at 1-ten thousandth of all existing currencies, it would trade at. And one-ten thousanth seemed very possible on the low end, so 21 million was decided. The 21 million number comes from the subsidy halving algorithm. Using basic calculus, you can see that this series approaches 21 million, but it only reaches it after an infinite number of blocks.

So the maximum number of bitcoins is 21 million no matter what, but the actual number of bitcoins that will be generated in practice depends on how long Bitcoin continues the halving.

Currently, Bitcoin must stop halving after the block reward would go below 1 satoshi because there's no way to express smaller amounts. Stopping at this point leads to the the 2. But the total amount won't go over 21 million. The reference client uses doubles in a few places. This is a problem for clones like dogecoin where it's not possible to send some amounts using the RPC interface due to a lack of precision in the double type. There's no problem with using floating-point numbers to store money values if you're careful to properly round the floating-point numbers when converting to or from the floating-point format.

It's doing math with floats that's likely to cause errors. If you use bitcoind, then you're using doubles to store BTC values. This is totally safe. And if the satoshi ever gets subdivided, this will cause problems.

Integers within that range can always be represented exactly. Furthermore, if an integer can be represented exactly in a floating-point number, then you can put a decimal point anywhere in that number without adding zeroes and the resulting number can still be represented without losing precision, though some trailing decimals may be added which will be removed if you round properly.

Bitcoin has a maximum of 2 51 base units, so any BTC value can be exactly stored in a double-precision number. Personally, I would've intentionally made them go over the limit so that potentially subdividing the satoshi wouldn't cause correct implementations to have problems. Yes, they are inappropriate for monetary values in the first place, most programmers dont seem to get it.

Actually, now that I'm looking at the client I don't see where it uses double s for actually working with money itself, just for things like time. To answer your question: You shouldn't be incorrect so that it's easier to be equally incorrect in other languages. It's not like biginteger libraries don't exist.

I've reviewed it and i dont see where I dont see any place that used doubles for storage and or computation of satoshis. The problem is that when I try to send a large amount of dogecoin, a rounding door in the flowing point conversion adds a few satoshis to the amount that is sent, and so the wrong amount is sent. And when I list account balances, they're wrong too. It doesn't affect Bitcoin, not because doubles aren't used they are but because 21e14 fits into a double without rounding. But seems at first to be an equally arbitrary number.

Also, I don't think that they decided on the block reward or halving interval so that the maximum number of satoshis would fit in double-precision floats, but rather they decided on those somewhat arbitrarily and then just allowed for as many digits of precision as would fit.

That's why the maximum number of satoshis, roughly 2 That explanation is close but not entirely compelling. Well, that's 9,,,,, satoshis, which is not anywhere close to 2,,,,, satoshis or even 2,,,,, satoshis, which is the actual asymptotic limit. If you assume a fixed-point format with two decimal digits of fractional precision which is typical for money , then a signed bit integer can address up to 21,, My guess is that Satoshi derived the million limit from here early in development and then later realized that this wouldn't be enough currency units and so extended the number of decimal places from 2 to 8 and changed the variables from bit to bit.

Actually, the total number of bitcoins that can actually be produced is 20,, So just shy of 21M. He didn't choose 21 million. He chose an initial block reward of 50 BTC, a block every 10 minutes, and a block reward halving every 4 years. The result of those choices is a total supply of 21 million, but the total number wasn't the goal, the parameters that led to that total were the goal.

I can understand starting out with 50 BTC as a block reward. But why half the reward every , blocks? That number seems quite arbitrary to me, even if it roughly corresponds to 4 years. The block reward isn't set to halve every 4 years it ends up being roughly that but instead specifically , blocks. I think he chose that half-life for the reasons I mentioned here.

He chose a reward scheme and 10 minute blocks. When he did the math, it came to 21 million. He didn't choose the 21 million, he just accepted the consequence of the parameters he chose.

The total limit is a result of the initial block reward 50 BTC the block half-life that it takes for that reward to be halved , I think those were intentionally chosen to end up with 21 million bitcoins because of the figure that all gold mined in human history can be fit into a cube roughly 21 meters on each side. Satoshi created bitcoin with the idea of being sort of a digital analog of gold finite supply, mining, etc , as well as the fact that it built upon Nick Szabo's "Bit Gold" proposal, so I think that 21 million was sort of a clever nod to that.

Keep in mind that due to coin rot there will never be 21 million BTC available. It's possible for example that Satoshi destroyed his private keys, ensuring that there are already at least k coins lost forever. Coin rot - Slow degradation of coin supply over time due to lost private keys or decryption passwords.

I don't like that term. Rot seems like a poor choice for the gradual loss. Physical dollar bills can rot, but the digital coins are as permanent as can be. It seems to me the 'loss' of coins is more like evaporation. They don't deteriorate, they just change from a retrievable state like water in a bowl to vapor in the air that is no longer under anyone's control. It goes to join the cloud so to speak. Cause it's a good catchy number the sheep like. It's not gonna matter when they dilute it to 21 billion and beyond.

For now it's a wonderful carrot for the lemming masses.
