A lot of emails are being sent to me about the KYC in airdrops and its a total shit, be careful on clicking links. Not just in airdrops but in everything here in cryptoworld, bounty can also be a scam so take time to read about the ICO, ask for some details and ask for your friends to help you know if the project is a scam or not.
Don't send your private details to some random people on the internet, they can use your id for doing something bad such a creating exchange account and pass the KYC procedure and then sell those accounts to another people, we all know that demand of this thing is very high. This is the trick that scammers are doing creating a fake airdrop and collecting people's details. I'm advising to not upload your ID even especially in participating in airdrop it's so dangerous.
