Bitcoin surges 750% since Buffett's 'rat poison' warning in 2018

Bitcoin has surged approximately 750% since Warren Buffett famously called it "rat poison squared" in 2018, even as the investment veteran has maintained his skepticism toward cryptocurrencies. The digital asset has reached record highs exceeding $126,000, driven by increasing institutional and investor participation, though it has since experienced a sharp correction.

Buffett's long-standing concerns about Bitcoin stem from fundamental disagreements about its value proposition and utility. His cautious stance reflects broader questions about cryptocurrency's role in a diversified investment portfolio.
