which it's clearly not, because as you said at the moment it's new and complicated.
I should have made it clearer, new and complicated
for the majority of people but the least they can do is get themselves educated with this new industry standard.
At this stage, I'm sure the vast majority of players (at casinos at least - dice sites might be different) don't care or don't understand about provably fair.
That is why, people should just get themselves educated with this new standard or left behind. As I have stated, people only "care" about it whenever they lost but whenever they win then most will probably let it slip through.
casinos have a mathematical advantage already in their favour, they don't need to cheat players.
House edge is what makes the house will always be profitable in the long run however this is not a guarantee that the house wont be cheating. A gambling site doesnt have to cheat to win because there is a house edge but history has proven that there has been some sites that have been caught cheating their players
999dice is cheating by tampering your roll result ( references below on how they do it and they are probably still doing it right now ) and also dicebitco.in was caught skipping their nonces but they claimed that it was a mistake of their employee but probably they will still continue to do so if they werent caught red handed
