Christian Langalis, known for his viral photo-bombing of Janet Yellen with a "Buy Bitcoin" sign during her 2017 Congressional testimony, is auctioning off the iconic sign. Langalis, whose stunt garnered international attention, plans to utilize the proceeds to fund his startup, Tirrel Corp.

Auction Details:
The "Buy Bitcoin" sign, drawn on a yellow legal pad with a Uniball Vision pen, will be listed for auction on Scarce City, an online marketplace specializing in physical and digital collectibles. Bidding will commence on April 18 and run for a week, with final bids accepted in person at PubKey, a bitcoin-themed bar in New York, on April 24.

Proceeds for Startup Funding:
Langalis intends to use the proceeds from the auction to support Tirrel Corp, his pre-seed-stage startup focused on developing implementations and wallets for Bitcoin's layer-2 Lightning network on Urbit, an open-source software project reimagining the internet computing stack.

Potential Value and Significance:

While Langalis refrains from speculating on the potential value of the sign, he recently received a private offer of five BTC (approximately $350,000) for it. The sign, created when Bitcoin traded around $2,400, holds historical significance as a symbol of early Bitcoin advocacy and awareness.

Community Celebration:
To commemorate the auction, Langalis will host a bidding event at PubKey, inviting the Bitcoin community to participate in person. A replica of the iconic sign already adorns the walls of the establishment, serving as a reminder of the pivotal moment in Bitcoin's history.

Legacy of the Bitcoin Sign Guy:

Langalis's impromptu action, although resulting in his removal from the hearing room, catalyzed widespread attention to Bitcoin. Despite being unaware of the viral sensation at the time, Langalis's "Buy Bitcoin" sign remains an enduring symbol of grassroots advocacy within the cryptocurrency community.
