April 11, 2022: -At a bitcoin conference on Thursday, billionaire venture capitalist Peter Thiel said Warren Buffett tops an “enemies list” of people trying to stop the cryptocurrency.

“Enemy number one,” Thiel said to a booing Miami crowd, is “the sociopathic grandpa from Omaha.” Buffett’s Berkshire Hathaway is based in Omaha, Neb.

Thiel, who by 2018 had reportedly amassed hundreds of millions of dollars worth of bitcoin through venture firm Founders Fund, also called out JPMorgan CEO Jamie Dimon and BlackRock CEO Larry Fink. Thiel presented large graphics with images of the two financial executives and their bearish comments about bitcoin.

The images all contained the word “gerontocracy.” About Dimon, Thiel said his views are part of “the New York City banker bias.”

Peter Thiel held up a headshot of Buffett with the words “rat poison” on it, referring to when the Berkshire CEO dismissed bitcoin using that phrase. Another quote from Buffett read, “I don’t own any, and I never will.” Earlier this year, Berkshire invested $1 billion in Brazil’s Nubank, an online bank popular among crypto investors.

The Miami tirade is Thiel’s latest and boldest public attack on the people he sees as standing in the way of bitcoin’s progress.

“This is what we have to fight for bitcoin to go 10x or 100x from here,” Thiel said.

He added that those investors are pleasing touting blockchain, the cryptocurrency’s technology, but feel the need to take down bitcoin and its legitimacy.

“When they choose not to allocate to bitcoin, that’s a deeply political choice,” said Thiel, a prominent backer of Republican politicians, most notably former President Donald Trump. Buffett, Thiel said, invests in a “list of woke companies.”

At one point, Thiel presented a colorful photo of Miami next to the word “youth.”

“We need to say, you know, you have to get on board with this,” he said.

A representative from Berkshire Hathaway didn’t immediately respond to a request for comment, and a JPMorgan spokesperson declined to comment for this story.
