and at this time airdrops for new users on some exchanges with kyc pass requirements and make transactions or hold one of the coins or tokens will get a 10-20$ reward for trading and of course airdrops that actually pay the hunters tend to give more rewards rather than an airdrop scam that bombards the media easily
Exchange airdrops as you mentioned are certainly not recommended because it will pose a big risk of misuse of our identity information and usually the one holding the event is a newly registered exchange platform so there is no guarantee that identity will be safe, honestly I don't like participating in airdrops that require us to for KYC because the $10-$20 reward is very inappropriate if the stakes are our personal information.
