depends upon the market completely if holding token seeks a higher value then it could be a good option whereas trading is a dynamic process it where circulation of the token helps to gain profit it is completely dependent on the people to trade or to hold
In my case I am currently holding my bounty tokens due to price dump. I am waiting until its value gets high or at least return to its original price so that it wouldnt be a loss for me if I were to sell it. But these two options depend a lot on your needs. If you badly need money, you could sell immediately but if youre not and youre wanting for a high profit, better to hold for the mean time.
