You can bet with crypto on there so you don't have to actually give them your information because you can just use an anonymous crypto wallet. It used to be a lot better before it was commercialised. In the past, all the markets were fee-free, and it was just your typical degenerate crypto gambling site. Now they've started charging fees on most of the markets, and they advertise everywhere so it sucks. Now they're a for-profit enterprise or something and act exactly like any other scummy casino operator.
But the payouts are done algorithmically on the blockchain so you can be sure that winning bets are indeed actually paid.
