Is KYC necessary for any airdrop? As of my understanding, it's needed only when someone is investing; in most of the cases after a certain level of investment say 10K or more.
Yeah, if you want to give out your tokens, there's nothing stopping you. Simply, they can not promote their brand differently, and therefore resort to the help of this mechanism of distribution. And then they take away the possible risks, in other words, they throw overboard those who helped them succeed.
