yes, the KYC is not mandatory since they do not ask it upon registering. and yes, they can ask for a KYC anytime.
yes, they most probably will. most gambling casino that has a KYC implemented on their website asks for KYC when an unusual(not sure what is their criteria for unusual) withdrawal is requested or when a big amount of funds is being withdrawn.
yes, to be honest, I think their 18+ on their website is just a warning to the underage gamblers that if they are proven to be underage all their funds, winnings, progress, etc... will be forfeited.
we often see warning like that the one that is 18+ sign but i dont think under age people will get turned off and wont access the site because of that because in thier heads how will the site know that they are underage anyway ? except if they are being required by an id or a kyc before they can enter the site
. if the gambling site has an auto withdraw , huge withdrawals arent included to that ? or only this site we have here does not conduct an auto withdraw function .
