Once bitcoin miners have unlocked all the bitcoins, the planet's supply will essentially be tapped out. Once all Bitcoin has been mined the miners will still be incentivized to process transactions with fees. Article Sources. Investopedia requires writers to use primary sources to support their work.

As it is not entirely so important how many Bitcoins will exactly be mined. Satoshi could have easily chosen almost any number. He could just adjust block reward halving blocks , reward sizes 50, 25, As miners validate transactions and create new blocks, they receive the remaining coins from this pool as a reward.
This number changes about every 10 minutes when new blocks are mined. The current reward sits at Because many miners are adding new hashpower, over the last few years blocks have often been found at 9.
This creates new coins faster, so on most days, there are actually more than 1, new Bitcoins created. After 64 total halvings, there will be no more Bitcoins left to reward miners and all 21 million BTC will be in circulation.
Right now, miners earn most of their income via the block reward. Below is a formula expressing Bitcoin supply as a function of block height:. Sign up to join this community.

Artefact, yes but that is not the theoretical limit Note that there are some assumptions built into the timing and unless the protocol is changed, they will actually be mined a bit earlier than this chart suggests. Or later--if the value drops precipitously and difficulty takes a while to get low enough again. But the graph is a good rough approximation. I think that's very unlikely.
Even if there are a few precipitous drops, I think that will be outweighed by the overall trend of increasing hashing power and they'll be followed be precipitous drops in difficulty. But, yes, that is possible.
I think saying "hard wired" is a bit misleading. The production schedule is coded in the software and could be changed to create more bitcoin. Fortunately anyone or any group that could change it is strongly incentivized to maintain the limit as it is integral to our idea of and trust in bitcoin.
This is actually the right answer. Gregory - what does this mean in practical terms after ? Carefully note the date on that BIP. You should provide a little more details: are you talking of an integer overflow case? Is this code located in the reference implementation or in a pull request proposed by a BIP, and which one?
