In my opinion. holding it is necessary if conditions are not favorable for us. people hold coins because prices are too cheap. if we do not hold and force the will to sell, we will suffer losses.
If you buy when it is cheaper, you can gain profit right now. You have to know how much you are longing for to hold to avoid big losses. You are holding because you want to gain profit which is depend on your decision if you want longer term or make it short term and trade on the market.
