The Buffett Paradox: How Berkshire Hathaway Built a Hidden Crypto Portfolio While Its CEO Calls Bitcoin "Rat Poison"

The world’s most famous crypto skeptic has a problem. Warren Buffett, the investing legend who once called Bitcoin “probably rat poison squared,” built a reputation on dismissing digital assets as worthless. Yet his company, Berkshire Hathaway—valued around $1 trillion—has quietly accumulated meaningful stakes in crypto-adjacent investments. The contradiction is harder to ignore than ever, especially with Bitcoin now trading above $89,000 (up from the previous milestone of $100,000).

A Decade of Crypto Criticism

Buffett’s hostility toward cryptocurrency is well-documented. During Berkshire Hathaway’s 2018 shareholder meeting, he didn’t mince words: Bitcoin was not just dangerous, but “rat poison squared.” Charlie Munger, Berkshire’s longtime vice chairman, was even harsher, calling crypto trading “dementia.”

That same year, Buffett doubled down on his warnings to other investors. “In terms of cryptocurrencies generally, I can say with almost certainty that they will come to a bad ending,” he told CNBC. The message was clear: stay away.

By 2022, Buffett’s position hadn’t softened. When asked if he’d buy all the Bitcoin in the world for $25, his response was dismissive: “I wouldn’t take it because what would I do with it? It isn’t going to do anything.” To Buffett, crypto generated no cash flow, produced nothing tangible, and offered no fundamental value.

But Berkshire Hathaway Is Playing a Different Game

Here’s where the story gets interesting. While Buffett publicly scorned cryptocurrency, his company was making strategic moves that suggested a more nuanced view. In 2021, Berkshire Hathaway invested $500 million into Nu Holdings, a Brazilian digital banking company, followed by another $250 million. The twist? Nu operates its own crypto platform—a fact often overlooked in discussions of Buffett’s crypto stance.

That’s just the beginning. Berkshire Hathaway owns 433,558 shares of Jefferies Financial Group Inc., a major financial services player. Jefferies, in turn, holds a substantial stake in the iShares Bitcoin Trust ETF—the largest spot exchange-traded Bitcoin fund globally. This means Berkshire has an indirect but meaningful exposure to Bitcoin’s price movements, even if Buffett would never frame it that way.

The Contradiction Nobody Talks About

These investments reveal a gap between Buffett’s public rhetoric and Berkshire Hathaway’s actual portfolio strategy. For a CEO famous for meticulous transparency, the disconnect is notable. Either Buffett genuinely doesn’t view these positions as meaningful crypto exposure—a thin argument given their size—or his company is hedging against the possibility that his judgment about digital assets might prove wrong.

Recent market developments have only amplified the tension. With Bitcoin surging and President Donald Trump throwing his political weight behind cryptocurrency adoption, the asset class has achieved mainstream legitimacy that seemed impossible a few years ago. Buffett’s $25-per-Bitcoin dismissal now reads as a prediction that dramatically underestimated crypto’s staying power.

What This Means Going Forward

Don’t expect Buffett to suddenly embrace cryptocurrency or reverse his public statements. His ideological commitment to fundamental value investing makes a 180-degree flip unlikely. However, the gap between his words and Berkshire’s actions suggests the company is preparing for a world where crypto—whatever Buffett thinks of it—remains a significant financial asset.

The real story isn’t whether Warren Buffett has changed his mind about Bitcoin. It’s whether Berkshire Hathaway has changed its portfolio strategy despite what its CEO says. That distinction matters far more for investors trying to understand what comes next.
