bitcoin, litecoin, nxt, protoshares, peercoin, mastercoin, eTherium. Litecoin because MAYBE there is room in the market for 1 shitcoin, then the rest because those are all of the ones that are actually innovative.
give me a marketable copy coin anyday, innovatives mainly for a very niche crowd, ltc just being the silver to btc gold will take it way further then most the 'innovative' coins as the public becomes more interested in alternative currencies.
