Before someone could proof that this website will NEVER sell or send the personal data to someone else, I will not suggest to do this KYC only for 50 or 25 dollars....
It's only for 2-3 meals but you never know how they could use your KYC..
Just as a reminder to be be careful, but if you are sure this project is safe, you can surely do that.
You can use a document that will expire soon and never use a national passport. This significantly reduces the risks, but they are still there.
