According to Odaily, despite Berkshire Hathaway CEO and Chairman Warren Buffett's well-known skepticism towards cryptocurrencies, recent actions suggest a shift in the company's investment strategy. Berkshire Hathaway has invested millions of dollars in Nu Holdings Ltd., a Brazilian bank involved in the cryptocurrency sector. The bank's stock has risen by 34% year-over-year, and it operates its own cryptocurrency platform.Documents from the U.S. Securities and Exchange Commission (SEC) reveal that Berkshire Hathaway's stake in Nu Holdings increased from 0.1% at the end of the fourth quarter of 2022 to 0.4% by the third quarter of the 2024 fiscal year. This translates to over 86 million shares valued at nearly $1.2 billion by the end of the third quarter of the 2025 fiscal year. This investment indicates that Buffett and Berkshire Hathaway are benefiting from a sector Buffett previously claimed to have limited understanding of.The move towards cryptocurrency-related investments suggests that Berkshire Hathaway may be reconsidering its stance on the potential impact of cryptocurrencies, challenging Buffett's earlier assertions about the industry's significance.
