we added in the site the bet and the proof
You did not add in any proof. You added in bets and links to transactions, but
still have not addressed my initial complaint: there is never any "most recent transaction" from every perspective on the Bitcoin network because transactions take time to propagate through the network. Therefore what is your most recent transaction is quite possibly not my most recent transaction, and therefore I have no way to know whether you are using your actual most recent transaction, or a transaction that was more favorable for you which could have been the second or third most recent transaction.
The player has no way to tell this.
...if any one can prove that we are cheating so he is welcom with his proof...
It would be very difficult to prove that a site is not cheating. However, it is very easy to prove that you are not
provably fair beacuse there is no way to prove that you are fair. It's right there in the name, it's that simple.
...the other dice can cheat and change the seed at any time , our proof are public...
This is not true at all. The other dice sites cannot cheat because
they are ACTUALLY provably fair. If they changed the server seed they were using, the user would be able to tell because the hash of the server seed they were previously given before betting would not match the preimage they were provided after betting.
Your claim that other dice sites that are provably fair can cheat is completely and totally bullshit. And again, you have no proof, because of the above reasons that I am now explaining for the second time.
if you have any suggestion you are welcom and we will try to update it for you

Switch to an actually provably fair system. Yours is not.
