However, I'd like to know if there will be BTC miners once the supply is fully mined, and will the fees for sending from wallets to exchanges be high? I also wonder if the price fluctuations will be similar to the current bearish and bullish market. Currently, BTC is widely traded, buying at a low price and selling at a high price. But will BTC trading be possible in the future, similar to daily trading? I think this is worth discussing...
So 2140 is more than a lifetime away so nobody can answer any questions today
about then.
We can only speculate and hope maybe that Bitcoin from then on will still be
bought and sold so miners will still be needed.
Hopefully Bitcoin would be still decentralised and so would be bought, sold and traded
24/7/365 which would more than likely still contribute to market volatility.
