Offcourse promotions will attract many gamblers to the site but the most important one is they should have a good support team to help you with the issues faced during the play or either deposit or withdrawal time. Deposits and withdrawal should be fast then many gamblers may like it because most of the don't like to wait. I don't like to play these games on mobile instead prefer to play on the desktop. It depends on individual interest.
Most of the time, most of the sites coming with unrealistic promotions are scammers. I wouldn't play on a website just because they have a great promotion and zero reputation in the market.
I do agree that provably fair is now the standard industry benchmark when it comes to crypto/Bitcoin. We have the technology, so it should be used. Cryptographic hashes lets us all prove beyond a doubt that we are playing at a fair place. Which is why normal non-provaby fair casinos are actually something we should just ignore and allow to die.
Well..online casinos should implement provable fair mechanisms as generally accepted by the online gamblers. Every site claims to be fair but not provable fair and that makes a big difference..
Actually, online gamblers and online casinos aren't really that familiar with Provably Fair. Provably Fair was only made possible by Bitcoin casinos, using the same cryptographic functions of SHA256 hashing that Bitcoin used, to allow people to themselves see if results on Bitcoin casinos were indeed fair.
Most online casinos today, if you check, only have Randomness certification, which you can choose to trust, but have no way to PROVE if it's true.
Hence, they are NOT Provably Fair. Big difference of Claiming to be fair, and letting everyone (the public) prove it for themselves.
