Just leave altcoins alone... the only thing that will be working in first instance is Bitcoin.
This, for the simple reason that you can ACTUALLY BUY GOODS WITH BITCOINS.
It's the most advertised and spread cryptocurrency and will probably stay like that for 5 years, maybe 10.
999 altcoins on 1000 are useless crap, you can't buy anything with them, no matter how better they are technically: if there's no adoption, it's just an experiment.
And the main hurdle for cryptocurrencies at the moment is having them adopted, and the focus is of course on Bitcoin.
Just keep your money or buy Bitcoins.
