The reward for mining Bitcoin is expected to see the second halving in its history later this year, potentially in June or July.
Bitcoin, a deflationary store of value as opposed to reserve currencies and fiat-money, has had its total supply limited to 21 million bitcoins since the original code released by Satoshi Nakamoto in 2008. Unlike fiat currencies that can be printed at will by central banks, the total supply of bitcoins is fixed by the consensus rules of the system. Because of its deflationary nature, the digital currency is often compared to precious metals such as gold, which also undergo a resource-intensive creation or mining process.
