Some ICO with airdropping is not also fine to get KYC for tokens worth almost nothing or a burger meal is not really fine. I observed it in some ICOs with airdrops that even with giveaways like that so small needs KYC? Don't fall for it guys, not worth it.
Some of them are using the personal information of the people who join airdrop that is why I sincerely agree to what you are saying. It is not really worth it, 10$-20$ in exchange of your personal information is way too risky. And it is fishy that they require KYC for such a small amount of money isn't it ?
