Well it would be 50% but if you add provably fair on the casinos, the advantage they have, it would seem like less than 5% of the advantage of the casino is against the player. And the more you play the more larger that percentage is and thats what I think is going on if you play in the long run.
of course we imagine a fair casino.. but if we have starting hash for provably fair..
much casino (i mean fiat casino) dont have provably fair
