I think, Taking profit is very importance and necessary in cryptocurrency. From your own experience so no matter how small or big profit so meke sure and take profit. Many people panic when they loses money. When you impatience then you loses money from trading. So need good expropriation and control Every situation your mind.
Yes ofcourse,most person's larment and cry after losing money throught trading,forgeting that experience is the best teacher,and without getting those loses and experiences,you won't do better in crypto and in trading.
I know every one expects profit,but one should know that the game is a risky one,which emotions must never be put first,else one is liable to get heart failure or attack.Therefore,when one is expecting positivity,one should also plan for negativity.
