Holding or hodling requires alot of patience and being patient waiting for the right time to sell is always the best, personally whenever I have I have a promising coin in my wallet, I normally hodl rather than sell it off immediately I get it, because I feel the price of that coin at the moment is undervalued so I simply hold and wait, and most times the price eventually skyrocket which you x5 return of whatever it was going to give back then.
