In Case anyone is looking to better understand UOS and how it works I found a few scripts I wrote way back when probably ten years ago. I used to add lots of notations because it helped me keep things straight. This might help you too.

VISIT SMITH WHITE HACK SERVICE FUNDS RECOVER

I'm Michell Franklin from Tuttle lane Colusa, California. United States. My special greetings to everyone reading this letter, If you are into Crypto currency investment then this message you need to read carefully as it will be of a great impact to your knowledge. myself and my family have been into crypto trading legitimately for the past 5 years and we haven't had such a great loss like the recent loss whereby we got robbed of our coins by a Chinese broker exchange scam who made away with our funds amounted to $3.850.000.
We have tried all our best to make report and get our funds back by seeking help from the force department in charge of handling fraudulent cases but nothing happen, we just only wanted the Chinese broker to help us in mining some coin so that the sudden falling or decrease of bitcoin won't affect us much but we later end up being scammed.
I told a friend at my office and she directed me to a hacker from Upwork and freelancer site then i did, the good thing is that a very good trusted hacker opens up to me that he has a trusted person who works anonymously for security reasons and he is the only one who can get the job done so he introduce me to [email protected] and also ask me to WhatsApp him in case he couldn't respond to my Email so i did exactly so by reaching him on WhatsApp at +1 (559) 508 2403 myself and SMITH WHITE HACK SERVICE got along and I gave him all the details about how I fell into the scam, he told me not to worry, his timing was 72 hours, he actually kept to his word and I confirmed the funds on my wallet. All thanks to this Hero at SMITH WHITE HACK SERVICE
