Do you avoid sites that ask for it? Or do you not mind as long as the site is good and trustworthy?
actually I have no problem to submit KYC if it is necessary... as long as it's a trusted and regulated platform, they should have a good reason to ask about my identity. maybe for other users they are a little reluctant to submit their KYC, but I personally see it more on the other side that it is required for withdrawal, and there is no other way but to obey it.
