Seems like the digital equivalent of buying casino chips and gambling with those instead of cash. I also fail to see how it will affect the ability of employees or the online casino from cheating.
The chance of winning anything in a casino depends to a very large degree on the fact that the order of the cards, roll of the dice, spin of the wheel etc. are all random. You can have high confidence in that randomness when you can see the mechanism that is determining the outcome, but I have to take on trust that a digital simulation is producing random results - and the person I am trusting is the person who has everything to gain by making it NON-random.
