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
I like to keep my personal datas to mai self. Regarding free tokens i agree with it if they offer services that i would buy, stuff like beauty products for example.
