It depends on yourself because you are in complete control of all the coins that you have bought. If you look back and there is a lot of speculation that makes a statement if the price of bitcoin is able to hit a high value again in the future, then with such high enthusiasm then the possibility of other coins also has the same potential. So, if you feel that selling it now has made you a good profit, then make a decision to sell. But when you are confident the price will increase even further and then hold may also be the right decision. The important thing is not to let greed control you for greater profits and remember you have all that control and not others.
