Almost all of us have asked this question. The only thing that annoys me is that I can't see the end.

As soon as the 21 million mark is reached, however, miners can no longer receive any BTC premiums. However, transactions must still be validated and stored by blocks on the blockchain - from this point of view, miners will at least be able to benefit from the transaction fees. This could become the lifeline for miners in the next century when no more BTC tokens can be released. So it says in Satoshi Nakamoto's Bitcoin whitepaper:

"As soon as a certain number of coins are in circulation, the incentives can be found entirely in transaction fees and completely free of inflation."
