Like gold, Bitcoin’s supply is finite. “Father” Satoshi Nakamoto designed Bitcoin as a digital gold with limited reserves to control inflation and increase the value of the currency. Therefore, the number of the most important cryptocurrency in the world is only 21 million Bitcoins.
Since its inception in 2009, 19 million Bitcoins have been mined so far, leaving about 2 million Bitcoins for future miners. Many people still wonder what will happen to the Bitcoin infrastructure and to the miners when the entire cryptocurrency is mined.
But the remaining 2 million Bitcoins will be the hardest to mine, as the amount of Bitcoins that reward miners for adding a new block to the chain will be halved every four years.
In 2012, miners were rewarded with 25 Bitcoins, by 2016, this number was only 12.5 Bitcoins. Currently, they only earn 6.25 Bitcoins per new block. Experts predict that by 2140, the supply of Bitcoin will be exhausted.
