I really can't see any reason for any other coin besides BTC. As far as I know, no other coin is accepted anywhere for anything. Not saying that in time, they couldn't be, but with BTC's divisibility, security and ease, what is any other coin but a hope at turning cash for a pump and dump on someone more naive?
Also, a fairly new one is BTB - aka Bitbar. Supposed to be more rare than BTC, and has in fact started trading with a value greater than BTC.
