Sad to see this but I must also say I am not surprised. Basically almost every casino that sponsored total degen streams like bossmanjack and goobr (or whatever his name is) is sketchy as fk.
If you ever win big you can only pray to receive your money since these sites don't really have big bankrolls to pay out big winners. And yeah, what they are trying to do is more than obvious, playing on time hoping the player keeps gambling and loses it all back quick.
Would be interesting to see a wallet address owned by jackpot, just to see if they actually have money.
