More and more airdrop is a lie, I do not recommend participation in airdrop, because there are at most a few 100 airdrop quality, so I think it should not be a waste of time.
this is the sad reality. Last year airdrop was so profitable but not now! Some developer just scam people out of what they called "selfdrop" where you can send Ether equivalent to some token! But the reality is the token have no value at all.
Yes, last year the airdrops were very good, now you should not waste your time on this occupation. Unless on the perspective project which can cost much in the future.
