The only reason Bitcoin is more valuable then other altcoins is first mover advantage. It's the truth if you compare bitcoin to a lot of alt coins on the technical side Bitcoin is lacking heavily. If the Protocol was updated to do something more like a lot of altcoins do I feel this is what would truly make the Bitcoin price sky rocket.
I agree, and first mover advantage does mean a lot though. You suggest Bitcoin changes to make it better, but I THINK part of the things people like about Bitcoin is that you can't really mess with it, or change it, without getting most people on board.
