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.
yes mine is pretty simple too, buy when price is cheap enough and sell while price rises good price, and i am happy of this strategy, it is basic and it works, so i get lots of profit from it, you should try it too
The above quoted method is the best to make good profit. Buy when the price is low and sell only after halving. Patience is much needed as halving happens only after 4years.
