And it can be said with great certainty that the possibility of recovering those coins is very low. So I think you should have immediately failed those coins from the airdrop when you got them because these types of projects only see all-time high prices at the beginning of the launch.
Usually it wiser to sell of any coins you get from airdrops because after launch, it's developers and main investors has very little purpose of such tokens after it's been listed. All they wanted was to make profits and so they won't want to let the profits pass on them. I've seen so many individuals who regretted holding airdrop tokens even for as long as a week. Don't hold, just sell off and make the best profit you can at the early stages of the projects.
Usually what common scenario happen is there a dump would happen especially that early adopters also devs might sell it early. To bad for them if they encounter a huge dump so instead of getting a profit already they might became a bag holder and will not get anything for the project they participated.
So what really be the best option to take is to sell and enjoy the profits they get. They should just try his luck on another airdrop if their concern is price increase since provably that they can gain more from other project after they dump the current project they participate. Also income from airdrop is uncertain so if there's a chance that we can get something, we better dump those tokens and forget about getting greedy since what's important is they already secure their profit.
