It depends.
If I am bullish on a certain token (e.g., $ETHFI) where I got airdropped twice, I wouldn't mind holding it for long.
As for the rest, it will be on a case to case basis.
But mostly I sell because I've got a lot of expenses and bills to pay for the month since I only relied on a client basis income and not fixed.
And since I began airdrops, it helped me from financial disaster and no doubt that even with difficult qualifications or so it would at least help me keep going on my every day needs.
