The reason 21 million is the right number is because people don't know how to value currencies. For instance, right now a Euro is worth $ USD and a Japanese yen is worth about a U.S. penny. Ask someone which currency they would rather hold right now and most will answer Euro, because $ is worth more than $ Dec 30, · Bitcoin was designed so that there is a finite supply of 21 million BTC. One explanation for the 21 million Bitcoin limit is the money supply replacement theory. An alternative suggestion is that the limit could be mathematically extrapolated from Bitcoin's operating parameters. Like many other cryptocurrencies, Bitcoin.

The reward that miners receive for offering up their computing power is halved every four years or so. While a miner would have received 50 BTC for successful verification of a block when Bitcoin first launched, the number is 6. The reason is that every bitcoin transaction has a transaction fee attached to it.
These fees, while today representing a few hundred dollars per block, could potentially rise to many thousands of dollars per block, especially as the number of transactions on the blockchain grows and as the price of a bitcoin rises. Ultimately, it will function like a closed economy , where transaction fees are assessed much like taxes. It's worth noting that it is projected to take more than years before the bitcoin network mines its very last token.
In actuality, as the year approaches, miners will likely spend years receiving rewards that are actually just tiny portions of the final bitcoin to be mined. The dramatic decrease in reward size may mean that the mining process will shift entirely well before the deadline.
It's also important to keep in mind that the bitcoin network itself is likely to change significantly between now and then.
