becarefull with exchange airdrop that required kyc at first , because most of them dont really give you what they promise,
for example, now they promise 50$ worth of their token, but at the end .. they will lock the coin and unlock it for 3 year , ahahah
well it's really just a way to attract the attention of many people so that their exchanges are known, only a few are really real maybe around 10% and you have to prove if you really pay because the personal data is not comparable with what is obtained especially if it is fake
