Actually I'd advise against buying litecoin at the moment. I have read a couple of worrisome things about them and I would wait for after we have seen the effect asics miner have on them.
Bitcoins are cheap atm, buy and hold is my call. Wait a couple of days actually until after 31st we could see it get a little lower than it is right now.
bitcoin is at like $765 right now, lite coin is $20
