I am selling it for 1 BTC. If you are interested, feel free to contact me. Thank you. I will not share any further details—those willing to take a leap of faith or use Mara can proceed at their own risk.

There are proxies involved, and hackers can obtain your private key (PK) even through them. You managed to avoid this because the addresses you used were not part of the 67 range from the challenge. The challenge addresses are already configured with proxies and other hacker tools designed to extract the key in just 5 seconds using an RTX 4090, lol.

I’m not saying that Mara doesn’t work; of course, it does, and it effectively hides the private key. However, you not tested it using the challenge addresses?. These addresses, starting from 67 and above, are actively monitored by hackers—even within Mara. They use SSH proxies and pre-configured scripts that might not even be known to the people running the system, but they are capable of extracting sensitive information in seconds.

With the wallets you tested, the bad hackers wouldn’t even bother trying to steal. Remember, the second mouse always gets the cheese.
