Everyone can only speculate or base their information on available news, but no one knows for sure what the crypto world or Bitcoin will look like in 100 years. And we certainly won't live that long, so why worry too much about Bitcoin's future when all we have to do is make the most of it while we're still alive?
And we all know Bitcoin will be fully mined around 2140, and we still have a long time to profit from Bitcoin in the long term. And I think everything related to Bitcoin will still exist, perhaps with some differences. Miners will still exist and operate, and miners will only receive transaction fees paid by people transacting or moving their Bitcoin from one address to another.
Yea that's absolutely truth, it's good that one vision about the future but 100 years from now is much a quite a numbers of years to get the required result on how the mining will look like , because definitely there must be other modality that creep in when many nation will fully adoption Bitcoin which you and me today may not forseen because life and human activities are full of changes that may even seem to be unforseen but be it ass it may mining will not live dinner imbalance at the end their must be a way out anything now about it is mere speculation on how it will end.
