I agree with you except streamers gambling fun money, I don't know who can bet that amount on a crypto offshore casino without a solid reputation. In addition the amount we can get is meaningless $1000 represents only a 0.1% cashback of $1 000 000. So I wonder if it's not just a promition to make people think there are many real high rollers gambling there.
unless there is something going on underground in that casino that is just between the Casino management and the gambler.
If there is, I think it is a strategy used by the casino to get funds in disguise. Possibly there could be such but how could it be that it is another way to money laundry through casinos based on terms between the gamblers and the casinos in question. At first verifying the authenticity of this bonus matters as to know how genuine it is so as no one would fall victim of any scam.
