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.
That's one opinion. Another opinion might be that the these supposedly "superior" or "innovative" altcoins are in fact dangerously insecure bastardizations of the bitcoin protocol.
The saying, "If ain't broke, don't fix it", comes to mind here. Though these "insecure bastardizations of the bitcoin protocol" have been, and will continue to be, extremely entertaining and profitable ventures to a few. I don't see them going away anytime soon, though a
small handful continue to be a good test bed for innovation in cryptocurrency.
