If someone creates a better digital currency, will you give up on Bitcoin?
not as if no one has ever tried and in concept, there are actually better currencies than bitcoin. Given the high tx fees and scalability problem, there are quite few coins that are better but the point is that bitcoin is the main thing. people based these currencies after bitcoin someway or another. So, it has most people in it. So bitcoin should always stay on top and i personally wouldn't leave it
