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?
Asking for that documents is not good for me because it is so personal but the good thing is that they asked it before you invest in their ICO. You have the option not to participate if you don't want to comply the KYC.
