If altcoins aren't dependants on Bitcoin price or value one altcoin would have over throne Bitcoin, if it was a different story that altcoins don't rely on Bitcoin bullrun I believe Bitcoin won't be the 1st today, am I wrong or right?
At some point, you will always wonder about that. Very possible in the long run, but definitely not today, specially that bitcoin is still on top for years to come!
I doubt in the long run where altcoin could dominance and dethrone bitcoin. If they aren't doing it right now, they wont in the future since that only consolidates and allows bitcoin to spread its root further.
