Anyone considering to take this offer: be careful, there is something fishy about it.
I'm thinking the same as you.
I don't trust a gambling casino if you can't find their domain name on who.is to verify how old the casino is.
It seems suspicious upon searching the casino.
Be cautious about this.
Last year, my cousin was scammed by a gambling casino introduced by strangers.
By using a referral code, he won a significant amount, and yes, it happened, but when it came time to withdraw his winnings, it required another deposit to fully access the remaining balance on the site. Until he got lured into it and was scammed.
So now, how can the forum users trust you, OP?
I am sorry to what happen to your cousin.

It needs an special kind of low-life scammer to lure someone to deposit into a scam casino in order to alledgedly get access to money they won as a result of their "good luck", hopefully it was not a life changing amount of money and he could recover from such loss in a short period of time.
Also, as far as I see it,.the only way someone in this forum could give the benefit of the doubt to OP would be if he agreed on hiring the services of an escrow and someone made sure there is not malicious software being distributed on that URL, which is supposed to be the webpage of the casino, this could easily be some kind of attempt to infect hundreds or thousands of computers with a virus to steal cryptocurrency wallets from our computers.
