I am a bit worried that
https://deviantbit.com/en is not mentioned here, or anywhere else. It is more worrisome that unlike most of these websites that were registered and active only for a couple of months, deviantbit was registered years ago.
Just checked it out and it's just an exchange and not a casino. Probably scam exchange. The people behind the scam casinos and exchanges keep registering more and more domains and so it's hard to keep track of all of them.
To be safe, never use such non-reputable services.
