I believe that the airdrop program is completely free, so if someone asks for a fee or transfers eth for reasons related to gas,
he probably should not send it.
let's start thinking, don't be easily provoked by obscure bait.
You are just feeding the scam developers once you pay for that transactions, there's no way that you should pay for anything whenever you are joining the airdrops. Better to keep away and find other projects instead, those who are not asking for anything just the wallet itself and received the value of tokens that they've promise to send you over.
