It depends, because not all of the altcoins listed in a certain exchange with a very low price doesn't guarantee you to make huge profit in long term, unless you're lucky enough to make profits in buying random cheap altcoins. In my case, XRP was the first altcoin I bought randomly with a very cheap price and I've sold it when I was happy to the profit I've made.

For a beginner, I don't really think diversifying your money on random altcoins is not a very good idea since luck is what we're talking about. I'd go for Bitcoin straight ahead just to be sure.
