First thing first, I didn't try to prove that gero2021 is not the bad guy here, he cheated, we can agree on that. But i think there's more to this than meets the eye. So, (un)surprisingly, I will try to take the role of the devil's advocate.

These are what we knows from the shared information and small date check are as follows:

• Paradice first launched their ann thread in 2 December 2019
• Somewhere between initial launch and 23 July 2020 they do site updates and tests new features on testnet
• gero2021 or also known as Caza played Paradice on 5 August 2020 with faucets and soon discovered a bug that allows him to bet negative, where double negative brings positive, thus 2btc withdrawn, and the rest 7btc, 24eth, and 5ltc were frozen by the admin

My questions:
1. From the beginning of the site launch up to whenever point, were there a team of beta tester?
2. If there were, do gero2021 part of this tester team?
3. Since the time of gero2021's manipulation and testnet is relatively close, is there any prove whether gero2021 played on testnet or on mainnet?
