Most potential coins 2021

Like Bitcoin, Ethereum only has a finite number of digital coins that can be mined.

Bitcoin has a maximum supply of 21 million coins, the last of which was forecast to be mined around the year 2140 back in 2017 – with the assumption that the rate of mining halves every four years.16 Mar 2022

Total supply refers to the number of coins or tokens that currently exists and are either in circulation or locked somehow. It is the sum of coins that were already mined (or issued) minus the total of coins that were burned or destroyed .
