It is a decentralized casino, hence, they don't need a gambling license. Unless, they will also accept btc, other alts and credit/debit card payments. If they are indeed connected with bitcoin.com, then, I believe, they know what they are doing. And their claims may be true. But to how we can verify their connections? That we need to do further research...
I don't get really get it your words that unless they will also accept btc other alts and the credit/debit card for the payment. On the other hand, I still know that cryptocurrency means blockchain and blockchain means decentralized ecosystem and as if they were providing their service directly with the wallet and claiming that they were decentralized casino that's means they were decentralized otherwise they would not have been decentralized casino. And if it is decentralized, there is no need with kyc verification and in this case if there is no kyc verification, most of the license providing companies do not issue licenses.
And about the claim that they were part of the bitcoin.com team it just need validate.
