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.
We are the same, I usually hold my coins to earn more profit and i am not the type of person to spend my money and invest it to coins, I work on bounty campaigns and i am always waiting for the price to decrease till i buy those coins. Patient is the best strategy in this industry, The more you wait the more profit you will earn.
