January 13 became an important date for Bitcoin - it was on this day that 80% of the total supply of this cryptocurrency was mined, namely 16.8 million coins.
The coins that can be mined are limited to 21 million. It was this quantity that Satoshi named in his white paper as a way to create a limited currency and prevent uncontrolled emission. Scarcity probably creates demand, which makes coins more valuable.
When 21 million Bitcoins are mined, they will become many times more difficult to obtain, so they could potentially become more expensive. Miners currently receive 12.5 BTC per block, but the Nakamoto protocol cuts their profits in half every 210,000 blocks. This means that by around 2020, miners will receive up to 6.5 BTC per block.
Not every cryptocurrency can be mined like Bitcoin. Some cryptocurrencies cannot be mined in the usual sense of the word. These are centralized systems where all digital money belongs to one company and is either in circulation or held. There is no way to mine such currencies other than by purchasing them.
Examples of such cryptocurrencies are IOTA, RIpple, NEM, NEO, Qtum, Omisego, Lisk, Stratis, Waves and EOS.
Whether such currencies can be considered true is a controversial issue, because one of the main qualities of cryptocurrency is the decentralization of its functioning.
