I have seen a tip from somewhere that in order for you to be become successful always in your trading, you have to to a sniper rather than a machine gunner.. If you trade always see all opportunity, every indicator, every momentum, etc. before starting to trade. Don't be hasty to trade every signal day. You just have to find that one trade that can bring you good profits and not painful losses.
My own opinion for you to be successful in trading is just to be patient every time the market prices are dropping in order to avoid selling your coins at its lowest price.
