Seems like the site owner can just deposit 10 BTC and have a huge chance of winning.
So could anyone else. You also have a small chance of losing 10 BTC. If you want to take that risk, do so. It's +EV after all.
I looked at the site and red flags pop up saying thats what is happening.
I don't see them when I visit. Scan for malware.
If you're saying you are seeing something that makes you think the site operator is cheating, please share it with us. The owner went to quite some lengths to set things up such that it is impossible for him to cheat. If you see a way he could be cheating I would love to hear about it.
I can't help but notice you have what looks like a URL for your account name. I wonder if perhaps you run a competing service. Could that maybe be colouring your vision?
I checked your so-called provably fair system and it's kind of laughable. You use the txid of the "last bitcoin transaction".
As you can see, the hash of bitcoin transaction is totally unpredictable
The problem is that the hash of a bitcoin transaction is entirely predictable. I can pre-generate thousands of them and have them ready for broadcasting. Then I pick a bunch that make my ticket win and broadcast them at just the right time. If I was you, I could then pick one of them and claim that it was "the last bitcoin transaction". In other words your system isn't provably fair at all. It's exploitable by players, and cheatable by yourself.
I think you should rethink the system you use before making such a half-assed complaint against a better thought out game.
If you look only 1 person buys a ton of tickets and wins every time.
Check the first draw. I bought a ton of tickets and lost. I haven't played since.
