If all Crypto Currencies are fairly similar and Bitcoin gets too high in price, won't people just trade it in for the lower priced ones? It seems like more stores will accept the lower priced currencies too. I'm just trying to get a grasp on things and to see what other advantages bitcoin has - besides being first in the market.
Merchant support, most secure. Other alt coins have high risk of dying and few died already, so dont keep alt coins for too long
