If you look the issue from the beginning, the site accused the player for doing exploit on the games but gives no evidences. Logically, the site should provide valid evidence for the accusation and the player will counter it with his own evidence. The fact, site did not provide evidences and even worst they delete all user's bet history. With this case, how can the player prove his innocence as what you say previously if he is not even able to see his own bets history? The only way to resolve this issue is, bithobo provide the bets history of this player along with its detailed information of each bet (such as server seed) then explain about how this player exploit it as they accused him.
