You decide the right time yourself, it depends more on what time you call the right time. Maybe you do not call it the right time unless you get 50%. But for me, with so many opportunities, it is always the right time. The main thing is to find the right one.
when my coins price increase high obviously i never sell my coins below my original buy so i always wait first until the price increase maybe like 1-10% increase then im ready to sell my coins to get profit
But you lose hundreds of opportunities until you wait for that coin. If you are doing this trading for profit, you will agree with me in this regard.
