In my opinion there is 2 ways:
The first one is to keep everything as it is (I mean keep your ETH and do not touch it)
The second way is about to making more profit, but as well taking more risk.
If you are interested it crypto as well as you like to read and learn new info about projects you should invest in other fundamental projects such as EOS, WAN, NEO, POA etc. (It is important to know the project before investing

)
Beside that, You may take 5-10% of your portfolio for ICO such as Fusion, Merculet, Block Collider.
