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.
Totally depends into your assessment but actually most of the time i would really be selling out immediately on the time that it would really be having value specially if its really that came from airdrop then you could really expect that there would really be that hard drop and if ever i do see a project which does have a good potential because of some factors like having that huge community support plus the hype then i would really be reconsidering on making up some buybacks on the bottom on which there would really be chances that it would really be reaching out all time highs after that hard drop but of course there would really be no guaranteed with this kind of method or ways because it would really be still all depending on different factors like community support on which i would say that this is the most important thing to be considered upon.
If ever you would really be able to make some good money from free drops then it would be ideal that you should really be keeping those profits for you to have on USDT form because on the time
that the market would really be having that drop or price crash then it would really be the best that you do have that right amount of buyback funds and this is what im doing ever since.
Never ever make your wallet to be zero specially on stable coins because opportunities do really come and go and if you dont have sufficient funds then you would be missing out those
golden opportunities.
