It could be beneficial but aren't USDT centralized? wouldn't
Yeah it's centralized.
that defeat wanting to gamble anonymously or without a central authority? although I understand gamblers wanting to gamble without worrying that their money would suddenly decrease its value but if they want to gamble without worrying about it why not just gamble on a fiat-based casino? wouldn't that be almost the same thing?
You don't lose your anonymity even if you are using a stable coin as it's still crypto.
The only difference with other assets like bitcoin and ETH from USDT is that it's not volatile, the value is fix and gamblers does not have to worry on the price changes, which I think would attract a lot of gamblers but for crypto in general, I don't think it's beneficial as real crypto assets should be the assets that we are promoting.
I see, thanks for clearing that up. in that case, having a stable coin on their gambling site would be beneficial for them and yeah, as you said, it would attract gamblers and most likely increase the traffic on their gambling site. if this implementation on their website prove to be successful, then I suppose it would just be a matter of time before other gambling site di the same thing.
