Promised the back of its business card at 2000 followers on X and shared it then, with every clue needed to find and claim 1 million sats.

Posted the card again in March 2025 and dared Grok to solve a hunt it called a.i proof.

Answered the Stacker News thread about the card anonymously, signed M with the schoolofbitcoin.com link, and told the players they had got further than anyone so far.

Who this is

A free online course. "Bitcoin education that everyone can understand", says the sign-off. Interactive lessons at schoolofbitcoin.com, a host called Miss Bitcoin, and @schoolofbitcoin on X.

And a business card. The front says "Learn Bitcoin. Be Free." under a big S.O.B. monogram. Yes, S.O.B. The back is a puzzle worth a million sats. Most people print a phone number there.

Marketing, or a real hunt?

Both, honestly. The back of the card was locked behind 2000 followers. The next big clue sits behind 10,000. One player on Stacker News called it "all marketing to get buyers". Fair suspicion. But the course is free, and the coins are real. 0.01 BTC, funded in October 2024 and never moved. Is that a sales funnel or a treasure? Why not both?

Talking to the players

The author doesn't hide from the hunters. When the card hit Stacker News, an anonymous account signed M jumped into the thread within a day. "Let the Games Begin :)". Then a wink at a player who found the hidden slide: "shhh.... dont tell... its a secret :)". Then an invitation to DM on X for feedback. Not many puzzle authors cheer from the stands.
