There is room in almost every coin for that kind of growth, but most won't see it. Asking people their advice like this is asking for bad advice. People will say whichever coin they're invested in.

Instead, like the rest of us, you should read up on each of the new coins and decide for yourself which has the potential to accrue value. I'm mining Vertcoin right now as I think it has good potential for strong early community, and consequently, later utility. I may be absolutely wrong. I debated mining Dogecoin when it launched, and, if I had done so, I'd now be considerably better off. Is my advice still valid? Decide for yourself.
