I think there's really no demand for it by traditional gamblers who have never played on a real provably fair casino. They just don't even know about provably fair.
So why would a traditional casino even make an investment to build a provably fair system?
...
I assumed that someone would ask what incentives a fiat online casino could have to actually introduce
a provably fair game. In my opinion the answer is quite straightforward.
The only fiat casino market is heavily saturated with lots of competition. If you manage to be the first fiat
casino brand that offers provably fair games this could give you a major competitive advantage.
I think I'm with eternalgloom on this one, and I will talk about my experience, and some of my friends. When I started gambling I did it only with fiat (partypoker, betfair, titanpoker) and similar big sites or networks, that offer both poker and casino. I only got to know provably fair when I switched to BTC. When I played on those big fiat casinos, I did not even know what provably fair was, and the same thing with my friends. So I don't really think they need to offer that, because their regular users just don't care about that. If one offered, maybe all others would start doing it, so again if there is really no demand for it, why do it?
The answer to your question is contained directly in the post of me that you quoted!
I´ll say it again:
If you manage to be the first fiat casino brand that offers provably fair games this could give you a major competitive advantage.That is a great thing for the brand that introduces an innovation like this due to the following reasons:
-implicitly the offers of your competitors look shady or at least not as trustworthy, because they are not provably fair (a user might think: "They aren´t provably fair, so probably they have something to hide, the games are rigged and so on")
-you could gain a higher marketshare in a highly profitable, but saturated market with lots of competitors
-you could stand out from the offer, because as Stunna pointed out many operators don´t really differ, because they get their games from the same
few game suppliers like NetEnt or Quickspin
-higher turnover, because some gamblers might increase their turnover, if they don´t have to worry about being cheated (I admit that they still have to worry a bit, because what good is a provably fair game, if you never bother to actually verify your bets)
