Key Range

[An1an1]

How to understand what range to look for a certain key ? for example 56 bits, 84 bits - is there a definition of what these addresses ?

[mirameshs]

no. actually there is no definition or map to calc bit numbers. there are many ways like statistical methods to find a range or focus on available wallets with certain ranges.

I want to understand why these particular wallets are hacked with this particular range in the description. How the range was chosen, by chance, or maybe due to the public key, or maybe some other distinctive

These are pre-planned issues and have not been created by chance or accident
Whoever made these issues intentionally put some bitcoins in them
Now, what was his purpose is a matter that we can talk more about later
There is no public or known solution for determining the range of a private key. There are lab tools for this purpose. There are also people and groups who claim that they can determine the range of the private key, but in my opinion, the range determined by them is so large that nothing can be done again, because if the range that They determined that it was small, they must have taken the bitcoins themselves. Don't you think so?
I have been doing a lot of research on these issues for about 1 year and I have reached some interesting results.
