Most of the time if I get something from airdrop I will sell it immediately if there's buy order at the exchange because for the project like this they won't go up in value as there's no development regarding the project. There's no point to hold it because you won't get anything for it later and you should sell it as soon as possible. I still have some token in my wallet that I forgot to sell, they used to have a little value about ~5 to 20 usd but now they are useless.
