No harm in trying your luck for a year. I don't think anyone is in the position to say what fate any of the crypto currencies will suffer over the coming months/years. In fact, I think it's worth sticking to one and see what happens. I've registered 25 or so Vertcoin domains plus bought 88 Vertcoins with 0.5 BTC.
PS. I do think Bitcoin is the one to back but I'm not in a position to buy 88 of those, hence backing an outsider...
