How I am managing my little fund is long term for my bigger investments and day trading for the smaller portion of my funds.
I spend 80% my fund for BTC, ETH and use 20% to day trade altcoins.
Btc and eth for a long term is a good choice. They will definitely give a good profit in the future. In the case of daily trading, I would look for coins that have the potential for a rapid price increase. Then you can earn a lot and quickly.
