The user @DarthCoin has hidden the mnemonic (12 words) for a Bitcoin wallet with 1 BTC in one of his guides. This is how I've tried to find it.
So the information that we have is that they are in one of the guides, in random order. We assume that it's in one of the 12 general guides, and in the English version. Which might be wrong but we have to start somewhere.
We can then look for words from the BIP39 list (2048 English words) and see how the matches look like in the text. This gives us way too many results and no clear pattern (nothing like 12 valid BIP39 words together).
So we need to make more assumptions to narrow the search space. What if the words where all in the same paragraph? If we look for paragraphs with more than 12 valid BIP39 words, there are more than 2500... Way too much.
So let's make another assumption. Paragraphs with exactly 12 BIP39 words. There are 14. That's doable.
So, how hard is it to find the right order of 12 words? There are ~480 million permutations of those 12 words. Luckily, because of the BIP39 standard we have some advantage, the 12th word is a checksum. So only 1 in 12 of those permutations constitutes a valid mnemonic. We are down to 14 paragraphs with ~50 million valid mnemonics from each.
How do we find the one with 1 BTC? That's the next adventure. We now need to derive an address from that mnemonic. Is it a Hierarchical Deterministic wallet? Let's assume so... But what address do we generate? Legacy? SegWit? Taproot?
In theory the words have been there for 5 years. That means it must be one of the old guides, and probably the address is not taproot(?).
I've written a script that derives the legacy address for each and checks against my mempool to see if it has any transaction history. It takes ~100h for each paragraph to check all. And maybe I was wrong in some assumption. Let's see how it goes :-)
The paragraph I'm the most suspicious about is:
You will never sell your bitcoins back for fiat, you only stay humble and stack sats</a>, spend, buy back or earn then. HODL is the ultimate duty.
Is
then instead of them a misspelling or a clue? Because them is not a valid BIP39 word.
