For me, if it's a short term thing, I'd invest a greater proportion in Bitcoin.

For long term trading, I'd consider Bitcoin and Ethereum. Litecoin is a great altcoin but I don't really think it is going to blow up like the other 2.

Additionally, there are some great coins under a dollar with great potential too. I'd advise you do your research on the various blockchain technologies before you invest.
