what if the casino makes you win to boost your confidence in order to increase the multiplier and then you lose when you wager all your total balance. I think when a casino is very fair in all their games, they will win the heart, the soul and money of all gamblers because they will always come back.
This is why 'provably fair' is important for most of the gamblers. They can verify whether the game is rigged in some way by checking on the hash if they're the same. Not everyone knows how to check this, but if you are thinking of gambling big time, you must learn how to use the provably fair function in order to not get screwed by platforms that only aims to get money from you. Not enough to base on licenses and what not. Those can easily be acquired by the casino anyway.
I also think that the publication of licenses on the casino website cannot be considered a 100% guarantee of the honesty of the casino.
Licenses are really quite easy to acquire because license trading is also a kind of business and it also has certain rules and tricks for making a profit from the sale of licenses.
Some more casinos, of course, can also falsify obtaining a license. For example, write that a license has been received, but in fact they just applied for it.
And of course other even more specific ways.
