From me and my experience, it's better holding it until the uptrend cryptocurrency really happens and there are many increases there, tokens will certainly experience an increase in price movements as well of course. My friend is a bounty hunter, and he managed to earn high profits from the many tokens he holds and sell it at the right time when the uptrend really happened, well he said.. usually the tokens went up in a few months after getting it from the bounty.
If you want to earn on the received coins,you should sell them. And if you want to use them to get access to the project or platform that released them,it is better to hold. It happens that for holding coins projects pay dividends or bonuses, or offer to use their product to pay for services.
