Nine years ago today, on July 12, 2017, during Federal Reserve Chair Janet Yellen's testimony before the House Financial Services Committee, 22-year-old intern Christian Langalis held up a cardboard sign behind her that simply read, "Buy Bitcoin." From that moment on, he became known as the legendary "Bitcoin Sign Guy."
At the time of the hearing, Bitcoin was trading at around $2,320.
Interestingly, Langalis was quickly escorted out of the hearing, but before that he had written his Bitcoin wallet address on the sign.

It was actually one of the best and most effective marketing in Bitcoin history.
And one of the best financial messages I've ever seen.
You know what's even crazier? It didn't require a million dollar budget or corporate campaign.
Christian Langalis held up the paper with those two words written on it at the perfect moment.
It's thrilling to imagine the situation, standing right behind the representatives of the traditional monetary system and doing this.
The crypto community appreciated the gesture and sent him more than 7 BTC as a reward for taking the risk.
We saw again how Bitcoiners, without any central organization, are always ready to reward people's honesty and courage.
It's still considered one of the most memorable moments in Bitcoin's history. Even more incredible, the original "Buy Bitcoin" sign sold at auction in 2024 for 16 BTC, which was worth around $1.03 million at the time.
Do you know that the money was not just cashed out, but given to the Bitcoin software development fund?
