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
If the airdrop free without passing KYC, i will participating on those airdrop but if we should pass KYC, i am prefer not participating. Airdrop give us little amount of token and sometimes not worth much when listed in market, better pass KYC in bounty because bounty more bigger than airdrop
