It started, as many of Marco's adventures do, with an irresistible idea.
In early 2022, somewhere between managing a multi-account investment portfolio, writing novels, and keeping tabs on geopolitical thesis plays, Marco stumbled onto unmineable.com — a website that promised something almost too good to be true: let your idle computer mine cryptocurrency while you sleep. No technical wizardry required. No expensive mining rigs. Just a slow old PC, a dream, and the faint hum of a processor doing something useful for once.
The coin of choice was obvious. Dogecoin. The people's crypto. The meme that Elon Musk had blessed with a wink and a tweet, sending it to the moon and back several times over. Was it a joke? Probably. Did that matter? Absolutely not.
The point was never the money.
The point was the story.
Grandpa was a crypto miner. That was the whole thesis.
Marco set up the miner on his mother's old PC — slow, dusty, past its prime, but still breathing. He named the operation with characteristic flair: manddminers22. Marco and Darlene, miners, 2022. He configured the worker, pointed it at the DOGE chain, and let it run. 166.67 hashes per second on the RandomX algorithm, one worker online, connected to one algorithm, doing its quiet computational duty day after day.
He never once worried that the electricity bill might exceed the value of the coins produced. That calculation was beside the point. You can't put a price on being able to tell your grandchildren, with a straight face, that you mined cryptocurrency on great-grandma's computer.
There was one catch. Unmineable had a rule: 30 coins had to be earned before you could collect your earnings. Thirty Dogecoin. At the pace of Marco's ancient PC, grinding away at fractions of a fraction of a coin per day, that threshold took a while to reach.
It took until June of 2026. Four years. One worker. One algorithm. 32.09734746 DOGE.
The moment the payout fired — June 12, 2026, 17:42:56 UTC, transaction hash 70cc0bc bla bla bla 201e7, confirmed on the Dogecoin blockchain for anyone who cares to look — Marco pulled the plug. Electricity saved. Point made. Story complete.
Except it wasn't complete. Because now he had to find the coins.
This is where the treasure hunt began.
Thirty-two Dogecoin had been sent to address D7Tc bla bla bla D8nB. That much the blockchain confirmed, plain as day on blockchain.com. The coins were there. Verified. Successful. A grand total of $2.81 USD at current prices, sitting on an immutable public ledger, belonging to whoever held the key.
The key, however, was another matter entirely.
Marco had a Coinbase account. He had a mining key — 1018163879 — which turned out to be nothing more than a shortcut for configuring mining software, not a door to any wallet. He had passwords that referenced cinbase, miners and years. He had a Dogecoin address that started with D and ended with nB and contained enough alphanumeric characters to defeat any reasonable attempt at memorisation. What he did not immediately have was the one thing that actually mattered: the private key or seed phrase that controlled that address.
Claude was summoned.
Screenshots arrived in sequence. The blockchain explorer showing the confirmed balance. The unmineable dashboard showing 0.00053168 DOGE still trickling in — the residual dust of four years of mining, not yet enough to trigger another payout. The mining key popup, confidently displaying 1016183978, which helped not at all. The key icon that promised salvation and delivered only a shortcut.
There were false starts. There were rabbit holes. There was a brief and exciting theory about an app Cold Wallet that turned out to be a dead end. There was the question of whether unmineable had generated the address internally — they hadn't. There was the suggestion of Exodus wallet, then Dogecoin Core, then Coinbase Wallet, each a potential path through the labyrinth.
Then Marco went looking through old notes.
And there it was. A Google Drive document, created sometime in the heady crypto days of January 2022, containing the archaeology of a man who had briefly become a serious digital asset experimenter. Written in the shorthand of someone who assumed they would remember what it all meant:

Doge D7Tc blah blah bla D8nB 1/10/22 310.35
Total gibberish to Marco four years after the fact.
But Claude deciphered it.
Twelve words. shed slouch chair finger train hawks plate luxury silk inform you petty.
The seed phrase for the wallet that held the 32 DOGE — and apparently quite a bit more.
The Coinbase Wallet app accepted the twelve words without complaint. The blockchain did its cryptographic magic. And what appeared on the screen was not the $2.81 treasure Marco had been hunting.
It was $630.10.
4,866.555 DOGE — $427.28. Not just the 32 coins from the mining payout. The wallet had been home to nearly five thousand Dogecoin from the 2022 experiments, sitting quietly in the dark for four years, appreciating and depreciating and appreciating again with all the dignity of a meme coin.
0.00233 BTC — $150.08. Bitcoin. Of course, there was Bitcoin. There is always Bitcoin.
0.0274 ETH — $46.08. Ethereum, for completeness.
1,330,000 SHIB — $6.65. Shiba Inu. The other dog coin. Because in January 2022, if you were going to do this, you were going to do it properly.
The transfers took minutes. One by one, each coin made its way from the self-custody wallet — where it had lived unattended since the Obama administration's final chapter of relevance — to the safety of a regulated Coinbase account.
There was one near-disaster: Coinbase initially offered a Base network DOGE address starting with 0x, which would have swallowed the coins into a cross-chain void from which no amount of screenshots would have retrieved them. Claude caught it. The correct address starts with D. All native DOGE addresses start with D. Who doesn't know that? The transfer was redirected. The coins arrived.
Final tally in Coinbase, on a Saturday morning in June 2026, four years after the experiment began: approximately $1,500 in digital assets, recovered from the memory of a slow PC, a patient algorithm, twelve words written on a Google Drive document, and one very persistent AI agent who had been simultaneously tracking Iranian drone attacks in the Strait of Hormuz.
The story Marco wanted to tell his grandchildren was simple: Grandpa was a crypto miner.
The story that actually happened is better.
Grandpa set up a mining operation on great-grandma's old computer in 2022, earned 32 coins over four years, forgot he had $1,500 in digital assets sitting in a wallet secured by twelve ordinary English words, found the treasure with the help of an AI that also happened to be managing his investment portfolio and monitoring a Middle Eastern war, and transferred everything to safety on a Saturday morning while a ghost named Mojtaba signed a peace treaty in Islamabad.
In the age of crypto, in the age of AI, in the age of everything happening simultaneously and none of it quite making sense —
This was a story for the ages.
But who was to tell it? The two partners of course.
Marco wrote an outline of how the story started and evolved, and then he asked Claude: “There is a story to be told. You write it from my outline below and fit in as many of the details of our treasure hunt conversation today as you please “.
And so you have it; what you just read, laid out by Marco, written by Claude:
Manddminers22.
One worker. One algorithm. 166.67 hashes per second. 2.81 worth of crypto coins over four years and a story for the age of AI
