Nowadays many ICOs offer free coins, but we have two problems with this free coins, the first one the value of this coins will drop after start trading due to a lot have free coins willing to sell it, and the second they ask for your ID (KYC), and i think it is very risky to send your IDs to any one.Please vote to help others
Yes dont send your ID for KYC just for airdrop tokens alone, how much can you get in that airdrop $2-$5? Its not worth it to send your ID just to get this penny. The only projects I join airdrops is when they have bounty as well to maximize my tokens on that project and take note that I always deeply research about a certain project.
