Just recently I saw an ICO that asking a monthly income and bank account statement for a KYC. It's said on their KYC form that it is important for them to know the financial capacity of their token holders or buyers.
What can you say about this requirements?
Somebody here did it before?
It looks like you are saying seriously, but in this case I do not think that it is necessary. What this group requesting is totally suspicious. So i think such kind of ICO is not safe to take part.
