Re: The Legend of Satoshi Nakamato, FINAL STEP PUBLISHED.... 4.87 BTC GRAND PRIZE!
Hi, can you send me a message to talk?
Looks like we both had "has not chosen to allow messages from newbies" setting. I disabled mine. Message away!
I made a new link here if people want to chat on Reddit about it (I think it's easier to follow conversations that way):

Re: The Legend of Satoshi Nakamato, FINAL STEP PUBLISHED.... 4.87 BTC GRAND PRIZE!
That one looks interesting but it seems to be dead now (no activity whatsoever for 5 months on reddit), but the server is live and it is what counts 
The server responses but its ssh responses changed during the course of the day today, as if they are constantly changing something.
Is anybody else trying to solve it maybe, even if it is a shared effort in between other puzzles - maybe we could create a dedicated thread (?)

I spent about two hours last night looking at that challenge. I ran all the commands I could across all the files and directories and saved a copy of all the files:

I wasn't able to get anywhere via SSH and I have no idea yet where this address comes from that someone on Reddit suggested is the one holding the coin: 1KWkDsv9VsdwsCWpJ2mu9R5AgUWgSPQHjf
I'd love to hear any thoughts that you are anyone else has.

And what is the address, which holds the 4.87 BTC?

What are the possible ways to access the account, meaning what should the solution resemble?
Private keys in bitcoin are 256 bits (32 bytes): https://en.bitcoin.it/wiki/Private_key
In both base 64 and base 58 (6bits per character) that would require 43 characters.
In base 16 (4bits per character) that requires exactly 64 characters.
Private keys can also be encoded in a WIF format (https://en.bitcoin.it/wiki/Wallet_import_format) that allows for validity checking. These are essentially the private key with 0x80 at the beginning and 4 checksum bits added at the end. Optionally 0x01 can be added at the end making for 296 and 304 bits respectively.
These most commonly appear as 51 or 52 characters in base 58.
With all that said I think it comes down to one of the following:
Find exactly 256, 296, or 304 0s and 1s.
Find 43, 51, or 52 groups of 6 bits.
Find 64, 74, or 76 groups of 4 bits.
Find 86, 99, or 102 groups of 3 bits.
Find 128, 148, or 152 groups of 2 bits.
