I think you have already clear about trust airdrop totally a time wasting program, where you can enjoy big amount token but there is no price. As airdrop was good time in fact of the year 2017-2018 this time many people make money from airdrop. Basically myself, i never participated any airdrop so if you want loss time then you can do it. Sounds like one think don't believe those airdrop, who want paying btc or eth.
