Who would bother with those websites? You have a lot of sportbooks which will be happy to take your business just on this market, and if you are willing to add fiat casinos to the mix, that number goes up dramatically.

So instead of wondering stuff like that, simply forget about them, as the risks that you will take by gambling there are massive, because that kind of sportbook could scam you whenever they want and you will have no way to try to get your money back, as the sportbook has no license anyway, so the people behind it are not afraid of breaking the law.
