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?
Your thoughts on this literary amazed me. Well basically the time frame is so much ahead that didn't even crossed this on my mind. Well for your question, miner's won't stop. Cause if they do so who will confirm the block. Rn miner's are getting paid by both mining the bitcoin and by taking the subsidy fees for every txn. So yes there's a chance that fee's might rise higher.
Some folks are saying that let alone txn fee won't be enough for miner's. Well we won't never know what will happened after another decade. Our technology is improving speed of light. I belive we will be advance enough in mining tech that it will be cost effeciency.
It's understandable that someday, BTC transaction fees will be expensive, as miners might want to make a lot of money from transaction fees. As I understand it, miners profit from transaction fees and block reward fees. Your opinion, such as high BTC transaction fees in the future, could be correct. However, I think it's possible that BTC fees will be cheap in the future, given the increasingly advanced technology and the increasing number of BTC users, which will potentially generate profits for miners due to the large number of BTC transactions.
However, I hope that BTC transaction fees will be cheap in the future, and I also hope that I'll still be alive and have a lot of Bitcoin. It's still a long way off until the BTC is mined, so now is certainly the right time to trade BTC. Thank you, everyone, for answering my question.
