so is it possible that those casinos doing their no KYC stuffs are not even registered? [/b]
It is possible that they are not yet registered and have started illegally. Starting with no statement of KYC registration in sign up stage, deposit stage or even withdrawal stage in their "Terms of service" is a big red flag and sign of a casino that may just have been opened for a criminal reason, a casino with no intentions to remain in the business.
KYC requirement is not only to curtail money laundering activities, It is also helping to reduce the increasing number of underaged gamblers.
