What is Bitcoin mining and how long will it take?

Currently, there are roughly 18,000,000 BTC tokens in existence. When the limit is reached, there will be no more tokens created. According to Decrypt.com, the last Bitcoin will be mined in 2140. 

Often referred to as the ‘digital gold’, Bitcoin is obtained through a process called ‘mining’ where ‘miners’ can produce Bitcoin tokens by solving a complex mathematical problem in the blockchain. Bitcoin has a hard cap of 21 million. Meaning, there is a finite number of Bitcoin tokens that can be mined.
