Every decision we made is good and not wrong but the problem is are we handling/managing it carefully and sure? Only two things we must have on holding our coins and it was knowledge and good strategy in order to grow and receive a good profit someday.
Holding is the way to earn some profit during the highest point value of our coins and then we sell it.
I think is good not panic and keep holding assets several day or weeks later, but for me when reaching profit target above 10% I will sell without worry price up later. I think we can't expectation for long term holding have bad issues some time make altcoin and bitcoin price dump, better still holding when price dump from we buy and selling later how long we hold after reaching profit keep selling it and not worry as panic selling some time.
