Mine is simple and the best. Buy low, wait, sell high. 
For extra I do day trading when there is panic making the price swing up and down.
Don't force yourself to trade that much, take some distance from time to time.

this is most basic trading strategy as if you won't panic and sell for bad price you will always get profit, as long as you will follow this rule
