What is safe here is that you are using a platform that does not ask for KYC. It keeps you anonymous and it does what crypto casinos are known for wherein they hide you, yet they allow you to bet on sports or gamble.
Yeah, Whale.io is a fantastic casino and sportsbook and i am glad we have them here in the forum. You didn't add fast payments and also zero withdrawal fees, all you have to pay is the network fees.
I hope you guys are lucky with your choice and win from your prediction.
I hope so too friend, i hope the same for you too.
