In which case it's not a casino but a confidence trick. It depends whether you trust the issuer of the stablecoin and its backing to survive a bank run. (Black Friday anyone?)

They could just disappear on you with your money, and you would be left with gas on a contract nobody wants anything to do with.

I agree and I'm not a huge fan of that type. I'm a bigger fan of the ones backed by ETH, as long as the price feed is reasonably decentralized.
