I mean every wallet must be personal and has identification like passport. This could be only way to track the bitcoins and prevent crimes.
I agree that it will be dominant as long as it is untraceable. Because, most people use bitcoin to send money without being tracked or pay things without tax. Paying bank for transaction commissions can not be the case that why bitcoin is valuable. I do think that bitcoin is a mind blowing development for the world but it is also very dangerous. It must be traceable or every country will ban it because of these reasons eventually.
