With wslconfig I didn't really understand in which folder to make the file, with what name of the folder, of the file and with what extension.

C:\Users\<UserName>\.wslconfig

The contents of the file:
Code:
[wsl2]
#Limits VM memory to use no more than 4 GB, this can be set as whole numbers using GB or MB

So no, if you find any keys with funds, unless it's a puzzle key, you should not touch them because they're not yours, so hands off the merch.😉
Yes, you urgently need to give these keys to me and continue to live in poverty, mama's son Smiley

Or under each range and a public key the new table is necessary?

verify(r,s,z,P2)


as you see two differents pubkey are valid for the same transactions.

what that means -> need finds "additional" pubkey for valid transactions for addres "0" or "n", then you can spend coins.
realy good mathematician can do.

Traceback (most recent call last):

And if you want to burn some bitcoin, far better to do it to an OP_RETURN output than a burner address.
Can you explain how to do this?
Do I understand correctly that there are transactions that cannot be spent even knowing the private key?

I guess it's always possible to use something like this for money laundering.
I.e.: (1) Send 1BTC to address whose private key is publicly known.
(2) See how your BTC was collected by someone else's bot.
(3) Cry because you are a loser  Grin

Hello friends;
I think I found a clue.
66. The probability that the wallet is in these ranges is over 90%

3B320044788A17DA0 - 3BC0ABFC3654BAE80
3475FBD690F7B3880 - 34B85C9495BA98840
30389466D233BCDE0 - 305E58789566D2EA0
2E1325EAAC24E8A40 - 2E6917C76BF8F5340


Can you elaborate on what these assumptions are based on?
Given that all previous keys were near the end of the range, I would only consider 3B and above
