Bitcoin Sign Guy Auctions Iconic “Buy Bitcoin” Sign
In a memorable incident from 2017, Christian Langalis, famously known as the “Bitcoin Sign Guy,” went viral after he displayed a “Buy Bitcoin” sign during Federal Reserve Chair Janet Yellen’s Congressional testimony. Now, Langalis is auctioning off the very same Bitcoin sign that he held up behind Yellen.
Bitcoin’s Impact on the Global Monetary Landscape
The act of Langalis holding up the Bitcoin sign on a yellow legal pad symbolized Bitcoin’s entry into the global monetary scene. Despite Bitcoin being a virtual currency, the sign has become one of the few physical Bitcoin artifacts widely recognized in the community.
Popularity and Memes
The “Buy Bitcoin” sign has garnered a cult following among Bitcoin enthusiasts, inspiring numerous memes, derivative works, and imitation stunts. Despite the sign’s playful origins, Janet Yellen has remained critical of Bitcoin.
The Viral Moment
During the Congressional testimony, Langalis cheekily raised the yellow legal pad with “Buy Bitcoin” written on it, capturing a moment that quickly spread across social media platforms.
After the incident, a spokesperson for the House Financial Services committee clarified that displaying signs during hearings was against the rules, leading to the individuals being asked to leave.
Langalis Reflects on the Sign
Reflecting on the incident, Langalis expressed how the network spirit transformed the image into a symbol of Bitcoin’s disruption in institutional finance. He emphasized the subversive nature of the message at the time and highlighted Bitcoin’s significant price increase since 2017.
Langalis is set to start the auction for the iconic “Buy Bitcoin” sign on April 18th, with the bidding closing on Wednesday, April 24th at 7 pm ET.
