Bitcoin is the best crypto currency and it will remain dominant forever because of it's use commercial use and investment. Bitcoin is a more trusted coin and it is of a greater value in price than all other coins (altcins). Most of the altcoins are prone to crash to zero later as time goes but bitcoin can never crash to zero. So bitcoin is more better than altcoins due to its high demand and altcoin can never be as good as it not to even talk of being better than it.
