If all Bitcoin has been mined, where does the miner get income from?
At present, as of June 24, 2020, the number of Bitcoin mined is 18,413,062 BTC. The remaining mined is 2,586,938 BTC.
The question is, if all Bitcoin is depleted, where does the miner get income? The answer is the transaction fee, also in the form of Bitcoin, as is currently the case, in addition to the new Bitcoin rewards.
Can miners cover mining production costs by relying only on transaction costs? If you can't, the miner can even close down.
But there is a relatively negative impact, namely the swelling of transaction costs, because miners practically prioritize greater transaction costs to cover operational costs.
But above all, we don't know about the future of Bitcoin. It could be that the majority of Bitcoin miners and developers agree to make changes to the core system of the Bitcoin blockchain so that Bitcoin can continue to survive. A Proof-of-Stake (PoS) consensus might be an option. Maybe not.
