its complicated to analize the peak of bullish cycle or bottom of bearish cycle. our analisys should be wrong but atleast we could minimize the risk that may occur later. the simplest thing we can do only close position when it give us enough profit, take a rest and wait another opportunity.
Every owner of Altcoin assets must have their own strategies and plans, and indeed if there is an opportunity to take advantage that is deemed sufficient, we should take it but not all of it. Don't have high expectations to always get fantastic profits until it's too late to get profits.
