Hello Nosters, is there any resources that explains what happened after a new #bitcoin is mined , how to trace the origin of a Bitcoin or a piece of Bitcoin.
As my knowledge the miners sells Bitcoin through the exchanges, is there another way they do that?
For example, how can i know the piece of Bitcoin i have is from the one that have been mined on the block xxxx?
