Based on a discussion I had with the team separately earlier today, they opened the website on the computer, before removing the internet connection and generating the keys.
I went ahead and removed my negative trust, because I feel bad for you, and you have had to pay dearly for this mistake. But this sentence right here proves you should never, ever make any private keys for anyone ever again. Full stop. You don't need a "team" to generate keys, that's the first fuck up. If it wasn't the well known malware you used, it would have been someone in this "team" to save the keys for later. There was so much wrong with how you went about this, that to think you can salvage your brand and make more products is astounding.
Let this thread be an example for anyone who wants to make their own coins. Don't. There is zero margin for error in this business. And without calling out this level of incompetency, we are only encouraging others to follow in your footsteps.
