Anyone could easily troll saying that they breached the security system of this casino and have access to the funds of user's and later on returned them back because he was having some morale.Roobet has not given any such indications so yes why should anyone give importance to his talks? By the way trolling doesn't have any proofs which shows the reality.
I believe that hackers would not even be here at all, we all know that if you are a white hacker then you provide proof that you hacked in and then ask a lot of money to show how it was done and then help with the fix if you can, if you do not want to help with the fix that's fine, you just breach in and show that you can hack into it and how so that you get paid by the casino.
If you are a bad hacker then you just steal money from the highest whales if you do not want to steal from poor and you still get away with thousands of dollars at the very least, probably hundreds of thousands of dollars. Since it is in crypto, you could turn it into monero and get away with it as well. There is nothing we could do to stop any of this, and hackers could do it without trying to talk their way into getting paid, they get paid without even saying much.
