Shouldn't it depend on the money? I mean we all know we are talking about a potential ICO here with the information given with the funding and in return we are getting a certain amount of money most likely not enough to worth it. However if we are going to just assume any amount then I am sure we can find a right amount.
Some people would be willing to give their information for 1000 dollars, some people would be willing to do it for 50 thousand dollars, some may request a lot more, maybe we need a monthly thing or maybe we need one time big thing.
Basically I am sure you can find people that will accept it for a certain amount, its just the question of how much. I am sure if this idea turned out to be real and you did it for 50 thousand dollars per person you can find thousands of people sending their ID easily. However, if you ask them they will say no while if you offer them they will say yes.
You sound like you can easily sell out your birth right for money. There are so many things that one really needs to guide against and everything should really not be about money. Damaged reputation is too difficult to regain when being lost than to regain money, and no matter the money you get, it will not stay for life.
You talked about potential ICO, what is the guarantee you really have that the ICO in question really has the potential, have you not seen lots of ICOs in the past that you believed to be potential, and yet turn out to be a shitcoins later in future?So KYC should not be about the money, but we need to be sure it will not cost damage to our reputation.
