The only problem in trading i think patience if you do not have a patience in trading you will lose.. because bitcoin price is unpredictable and if you are not smart and thinking that the price will going to dump mor just like in illustration the man who has no patience he sell his bitcoin for low price. instead of waiting more time that the price will go back to normal or increase more to make a profit..
So patience is the solution if you are in trading, yeah it is risky if you do not analyze the movement..
Yeah patience is always the problem in trading. Not only the lack of patience is the problem but too much patience will make you left by the train too. There are certain cases that holders were left bagholding a worthless altcoin due to waiting too much. Maybe it driven by a greed or a miscalculated prediction. But waiting is patience and this time there is too much waiting. So I think patience and timing is the best key in trading, you lack one , you will fail miserably.
