Many bitcoin gambling sites state that they are provable fair.
Let's assume they are.
But what if they bet on their own game many many times, wouldn't they increase their profit by doing so?
If they create the highest betting volume, they have a higher stake in the whole game.
Do I miss something?
I don't think that there is any possibility of cheating when game is provably fair..
Here it is well described:
https://satoshidice.com/provably-fair/I would rather have a source other than a gambling website.
I think creating large betting volume on your own website will benefit yourself when you are the owner.
When you win, you get the stake
When you lose, you lose to yourself.
Other tiny players can only win when they win
(dumb sentence, but I hope you get my point)
The owners of the site can increase their profit by increasing the betting volume. The only thing they really lose is the transaction fee I just figured.
