Personally if it has value when it enter exchanges I will flip it but for a more stable token. Most become valueless with time.
The main thing is to be holding a coin with value anyway and if that is not the case, I see no reason why anyone should be holding such a coin. The most important thing is to keep checking if there is any form of development going on and that makes it easy to know if one should keep holding or not.
I am not a big fan of airdrop since most of the time, it comes with pretty low value and you would not have anything to do than to hold anyway. Sometimes, the time and efforts taken for exchanging the airdrop rewards may cost more than we are getting from them.
But if we look into some successful coins of present times, I do regret why not participating into their bounty/airdrop and why not holding them till date. Unfortunately only very few people predict the future exactly and hold the coins like MR. Satoshi Nakamotto. All others are selling out on find some returns for their capital/time/efforts.
