My advice would be to consider investing it into 5 coins, holding too many coins would mean that you are not able to efficiently profit from any rises from a single coin, but holding just one or two coins is too much risk.

5 coins is a nice balance.

Have 1 of each: Bitcoin, one major privacy coin, one major smart contract coin, one ICO token/investment, and one small cap coin you like. I'd say have around 5% in the small cap coin, and around 24% in each for the rest. That should be a healthy portfolio.
