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.
The hype happening in the crypto industry has also encouraged bad elements to scam and deceive people. But I think not all airdrops are scams as there are others that are true to their promise of giving stakes to participants. So it is important that you must study the project before joining their airdrop campaign.
