Charlie and Chris Brooks run Crypto Asset Recovery, a small business in New Hampshire.
They have helped to recover some amount of lost passwords and coins.
Reading further, the Crypto Asset Recovery site made mention of bitcointalk.org to my amazement and I was glad to see that a thread in 2011 was linked to it on the site called Nakamoto's Forum and undoubtedly; that is here, this wonderful forum with lots of opportunities.
This is the thread titled: Let's add up the KNOWN lost bitcoinsExcerpts from the site
For Chris and Charlie Brooks, finding lost passwords to cryptocurrency wallets requires figuring out how their clients' minds work - and that effort can help their customers retrieve a slice of what the pair estimates is about $4.7 billion worth of recoverable bitcoin stranded in locked wallets.
The Brookses narrowed it all down to 72 posts that described the loss of at least half of a bitcoin. They determined that 14% are potentially recoverable cases and that from their own work in recovering wallets for clients, they can decrypt about 35% of passwords. That led to their conclusion that about 2.45% of lost bitcoin is retrievable. With a range between 68,110 and 92,855 bitcoins, that would make up to $4.7 billion in bitcoin recoverable based on the asset's price of about $50,372 on Friday.
One of our most recent cracks had about $250,000," in a blockchain wallet, said Charlie, who majored in computer science in college. He's put school aside for now to work at the business. "This is something I've always liked. I would follow along with my dad ... Online treasure hunting, it seemed really cool
We get as good a list of passwords as we can from a client and then we put our heads together and spend some time extrapolating the way that they make their passwords and try to get in their mind when they are actually creating a password," said Charlie. "That's the most helpful thing, just seeing their practice," he said. "That's the cornerstone of our business, essentially."
The duo will run "hundreds of millions or billions of variations" of password patterns and test those against the encrypted version of the wallet, said Chris.
"If you don't have a very good [password] guess, there are more possible passwords than there are atoms in the universe, and I'm not being facetious when I say that," Chris said.
I also think sometimes when we lose our passwards we can do a near guess of it from our bunch of passwards or stuff close to that and that has been one of the secret of the duo father and son.
I don't know if this particular link was on the above thread HERELets see if this will help anybody , thanks
