Weird, why don't you share the source of randomness to convince the other players about the fairness? How do you determine which account will get high amounts or vice versa? Wanna join but rules are not clear.
As I wrote, we use Random.org to create a random number and we are giveaway balance by the random number.
That's a total lie, explain to players how they can verify bets on random.org? If you use the random.org API you have no reason to hide such information, but you will not show it because you do not use the random.org API, now I can say that I am a superman and you will trust me?
User must be able to verify bets on random.org site directly
Ok, what about recording the screen of random selection? Maybe the other users will join the new promotion if they are convinced about the legitimacy of the promotion. Just find a way to convince the users about the legit randomness because they think cheating issues are normal for the new gambling brands.
