Lots of scammers are taking advantage of airdrops and scamming people, so if you are participating in any airdrop, make sure you don’t make use of the wallet where your funds are. Always make sure you have a separate wallet that you will be using to participate in airdrops. In case there is a hack  or the airdrop is created by scammers, then they won’t  be having anything that they will be moving from the wallet. But if you make use of the wallet which your funds are, they can hack into it, and everything that you have in it will be gone, so we have to be smart.
