The fork in the road where code met chaos and won.
A new batch of 13F filings dropped last night, and the crypto corner of Twitter exploded. The headline: Warren Buffett’s Berkshire Hathaway added a $50 million position in Nu Holdings—the Brazilian fintech that owns a piece of a crypto exchange. Within hours, tweets screamed “Buffett is buying crypto!” and “The OG value investor finally sees the light.”
But here’s the thing I’ve learned from 29 years of watching markets: the 13F is a rearview mirror, not a crystal ball. And the real story isn’t what Buffett bought—it’s what the crowd is selling themselves.
Context: Why 13F Files Matter (and Don’t)
13F filings are required by the SEC for any institutional manager with over $100 million in assets. They disclose long equity positions as of the last day of the quarter—meaning the data is already 45 days old by the time you read it. In crypto time, that’s a lifetime. Yet every quarter, the same pattern repeats: a hundred analysis pieces dissect Buffett’s moves, and nine out of ten miss the nuance.
This quarter, the seven funds in question—Berkshire, Duan Yongping’s family office, Li Lu’s Himalaya Capital, and Dan Bin’s private placements—showed subtle shifts. Berkshire’s Nu Holdings stake is real, but it’s a rounding error in a $360 billion portfolio. Duan Yongping, the legendary Chinese investor who once said “Bitcoin has no value,” added to his Apple position. Li Lu sold some bank stocks. Dan Bin, a Chinese fund manager known for betting on tech, bought more Nvidia.
But the crypto community only saw one thing: “Buffett → Nu → Crypto → Bullish.”
Core: The Data Behind the Hype
Let’s get technical. Nu Holdings (NU) is a digital banking platform in Brazil, but its subsidiary, NuCripto, offers crypto trading. The stock is up 60% in the past year, but the crypto exposure is indirect. Berkshire’s $50 million stake represents 0.014% of its portfolio. Even if NuCripto’s crypto trading volume doubles, Berkshire’s earnings impact is negligible.
More importantly, none of the seven funds bought any direct crypto assets. No Bitcoin ETFs, no MicroStrategy, no Coinbase. The only “crypto” exposure is through Nu, and that’s a stretch. Based on my experience auditing on-chain data during the 2017 whale alert, I can tell you: the market is conflating a fintech bet with a crypto conviction.
Here’s the key data point: In the same quarter, Berkshire sold its entire stake in Visa and Mastercard—two companies that process crypto payments. That’s a signal that Buffett is actually reducing exposure to the payment rails that crypto uses. The Nu purchase is likely a Latin America play, not a crypto play.
Contrarian: The Crowd Is Reading the Wrong Tea Leaves
The fork in the road where code met chaos and won.
What’s missing from the narrative is the silent signal: the funds that didn’t buy crypto. Duan Yongping, who famously called Bitcoin “rat poison squared,” added to Kweichow Moutai—a liquor company. That’s a bet on Chinese consumerism, not digital assets. Li Lu, a value investor who studied under Buffett, sold his entire position in Bank of America and bought health care ETFs. The contrarian take is not that Buffett is bullish on crypto, but that the big money is rotating out of cyclical financials and into defensive sectors.
If you’re a crypto investor, this should worry you. When traditional investors see the macro environment as risky, they tend to de-risk entirely—including shedding speculative assets. The Nu purchase might be the exception that proves the rule.
I remember the 2020 Uniswap V2 SushiSwap fork: everyone thought the fork was about code, but it was really about community loyalty. Similarly, this 13F season is not about crypto adoption—it’s about geographic diversification. Buffett’s buy of Nu is a bet on Brazil’s unbanked population, not on Bitcoin. The crypto crowd is using a quarter-inch lens to read a mile-wide map.
Takeaway: What to Watch Next
The fork in the road where code met chaos and won.
The real signal for crypto won’t come from 13F filings with 45-day delays. It will come from on-chain flows—like the steady accumulation of Bitcoin by addresses that haven’t transacted in years, or the sudden spike in Base network activity. Buffett’s 13F is a distraction.
Next quarter, watch for two things: whether any of these funds add direct exposure via a spot Bitcoin ETF (unlikely, given Buffett’s history), and whether the Nu position grows beyond a rounding error. Until then, the only thing breaking is the narrative—not the code.
Stay sharp. The market is always trying to sell you a story. Your job is to check the data.
