What would happen after all the 21 million bitcoins mined? How the transactions would be carried?
I don’t really know how things will be by then, it’s lots of years from now. But whatever happens, I believe it will be for the good. As many of the people said, miners won’t be paid mining fees anymore, they will only be paid transaction fees and tax fees, if I’m right.
There will be nothing like mining then. But if that’ will cause a problem, it will likely be that they can create a new cryptocurrency and move everyone who has Bitcoin over to it.
