You have a working website maybe you could generate ID for each bet then have a built in probably fair checker on your website I've seen that there's a lot of bets that is happening but wasn't able to check the fairness of their bets if you can't provide some info about its fairness i think no one is going to play on your game since it's what player is looking for the security and fairness of the casino or gaming platform.
As I can see with their stats website, they have bet IDs for each user.
