The Man Behind the Buy Bitcoin Sign: Christian Langalis Journey from Protest to Legend

Christian Langalis, once dismissed as a “Bitcoin kid,” rose to fame after holding a “Buy Bitcoin” sign behind Fed Chair Janet Yellen in 2017. A committed libertarian and early BTC believer, he held 99% of his net worth in Bitcoin and helped promote it in Washington. He now runs a stealth Lightning startup and continues to push Bitcoin forward.

BITCOIN LEGEND: CHRISTIAN LANGALIS

Told the world to buy BTC at $2,000
Sworn enemy of the Federal Reserve

A thread 🔥

In 2017, Christian held up a sign behind Janet Yellen

The sitting chair of the U.S. central bank

It made him a hero overnight in #Bitcoin, but that's not where his story begins...

Just 25 years old, Christian began his career at a global macro fund

There, he was the "young #Bitcoin kid" who wasn't taken seriously.

He realized markets were fake. He started buying $BTC 👏

Christian became a fierce Libertarian

He started reading everything he could about Austrian economics

He read the classics by Schumpeter and Rothbard 😍

Next, Christian joined the CATO Institute, the Libertarian think tank

He studied under George Selgin

He wanted to develop his own economic thesis on #Bitcoin 👏

There, Christian was asked to attend the Fed report to Congress

Bored, Christian decided to write "Buy Bitcoin" on his notepad

He figured he'd flash the sign, then collect the screenshot later...

At the time, the price was $2,300

#Bitcoin was in the middle of an epic run to $20,000

Here's Christian talking about what he was thinking when it happened...

Immediately, Christian was escorted out of the hearing

Bouncers descended and removed him from the event

You can even see him leaving on the livestream...

In the aftermath, Christian was showered with support.

He received over 7 #Bitcoin in donations

He became an overnight icon ✊

Christian's conviction in Bitcoin only deepened.

By that time, he was holding "99% of his net worth in Bitcoin."

"I won't be converting it back into U.S. dollars," he said. 🚀

In the years to follow, Christian used his celebrity to raise money for charities

Here he is with his trademark suit and tie, raising money for Coin Center

The non-profit helps defend Bitcoin in D.C. ✊

Today, Christian still believes #Bitcoin will revolutionize money

He calls it a "new financial substrate"

He believes 1 $BTC will be worth over $1 million 🧡

He's still working to move the #Bitcoin economy forward

Christian's founded a new Lightning startup

It's currently in stealth 👏

Fittingly, Christian recently auctioned the original "Buy Bitcoin" sign earlier this year.

It sold for over $1 million
