The least digital currency in terms of the total number of units traded is Bitcoin ($BTC Bitcoin).
Maximum number: There is a maximum and absolute limit to the number of bitcoins that can ever exist, which is only 21 million units.
Scarcity: This maximum creates an artificial scarcity that makes it different from paper currencies that can be printed without limits.
Current supply: These currencies are mined (produced) slowly through a process called "mining," and currently, there are about 19.7 million bitcoins circulating in the market.
Mining mechanism: The mining process will continue until around 2140 to reach this maximum.
Value versus number: The high value of Bitcoin (its high price) is directly related to this scarcity and the limited number of units compared to other currencies that may reach billions or trillions.
