I stopped trading only for two reasons: Bitcoin is growing very fast, which makes a good profit without trading.
Trade is very dangerous, those people who do not know how to do it, are likely to lose their money when trading.
Indeed, if you don't know what you are doing then your investment will be at risk, it's better to hold your coins if you don't have any idea on what you are doing, keeping your coins will be much safer while waiting for the big breakout, trading is for those who knows how to take the risk and have a good attitude towards this field.
