I've been thinking about something that I believe some people will also be thinking about, which is what will happen after 21 million bitcoins have been mined. Currently, I believe around 18 million bitcoins have already been mined within 10 years, leaving only 3 million bitcoins to be mined. According to projections, the last bitcoin will be mined by 2140, which means we still have 100 years before the last bitcoin is mined.

According to what I think, after the maximum bitcoin of 21 million bitcoins has been mined, miners will continue to be active, but they will no longer be able to mine more bitcoins. Instead, they will make money from transaction fees collected from each transaction.
This is just my opinion; please let me know what you think.

My question is;
- what happens after 21 million bitcoins have been mined?
- What will miners do after the total of 21 million bitcoins have been mined?
- Will the total supply be increased because some bitcoin holders have died and others have lost their private keys?
Pls your suggestion will be highly appropriate and I believe will also help other members.
