Damn! Any airdrop asking one to pay is scam. Also, I usually advise crypto enthusiasts, don't just click any random site you come across, some will even install spyware to your device. Some sites will ask noobs for private key or keystore, in a bid to hack their wallets. Let's be guided please.
Just a little bit curious how could you even call it an airdrop if you need to pay in order to receive it?
People are surely being blinded by their greed if they would fall on to this kind of tricks.
And also those airdrops that would ask for private key or keystore is clearly a scam so how could anyone fall for it?
Those new in crypto should be guided properly and know the difference between scam and legit airdrops if they want to join airdrops.
