It depends on the investor/trader/holder.

For example, I don't know how to trade then I'd prefer holding my coins. It will give lower profit in the short run but it is less risky compare to trading. Low risk = low reward.

On the other hand, if I know how to do trading then I'd prefer to do trading rather than holding it. It will give me higher profit but there is a higher risk on it because the price movement of crypto is unpredictable. High risk = high reward.
