In 2017, when Federal Reserve Chair Janet Yellen was testifying before Congress, a young man named Christian Langalis, who was a researcher at a think tank, had a sudden idea. He raised a notebook that said "Buy Bitcoin".

This small gesture made him an overnight internet sensation. Later, he framed that piece of paper with the Bitcoin buying advice and it was sold at auction for $1 million. Additionally, he received donations of 7 bitcoins because of this.

If you rewind to 2017, would you think he was a genius or just being abstract?
