There are two possible scenarios after the 21 Millionth Bitcoin is mined. Would it be good scenarios or bad scenarios mainly depend on the hardware that the network relies on. The only reason why people are mining is profit, and when we mined all of the Bitcoin miners will disappear that is sure.
The most reasonable situation after all of the Bitcoin have been mined is to charge a small fees for each transaction as a reward for the miners because they are providing computational power to the network. But reality is not that simple when it comes to the proposition above mentioned, let\'s see why. First at all, Bitcoin have been developed as a decentralized currency where people will be able to exchange Bitcoin for good and services online. There must be someone or something that will pay of this small fees to the users, so it mean that Bitcoin is no longer decentralized system, it will become centralized than. Also, there are many people including miners that are investing in this cryptocurrency hoping for it do became globally adopted and more valuable.
We all know that story where Bitcoin is being compared to the gold, when all of the Bitcoins is mined, this comparison would be even more accurate. The fact that supply of the BItcoin is finite is increasing demand and price as well, it is just question, when will miners mined all of the Bitcoins. When it comes to the future of Bitcoin after all 21 Million will be in circulation there are two possible scenarios, even the price and demand of Bitcoin will fell down permanently or the price and demand will go up and Bitcoin will became the most influential method of payment in the world.
