We all know that the amount or max supply of Bitcoin is only 21 million BTC, and according to Coinmarketcap the total supply has reached 19.77M Bitcoin which means the remaining Bitcoin that has not been mined is 1.23 BTC and will be mined until 2140.

So in your opinion, what is the job of Bitcoin miners if all Bitcoins have been mined?
