I was checking these Airdrops, they are usually asking for a telegram group join. All these groups are ending up having 50K + members. Ok, I understand that part, but at the end these groups are spammed by members, no real discussion is going on since there are so many comments etc. Is it worth it for ICOs to do airdrop? Anyone here who has actual numbers?

Hi,

Do you know any platform where you can buy tokens directly with credit card?
I have friends who find the process of buying eth and from there token complicated, any suggestions?

Do you know ICOs with real value behind? No big saying, no tech turn around, but something solid that actually brings revenue that is distributed?
