Peter Thiel's Founders Fund has significantly reduced its holdings in Bitmain, a NASDAQ-listed company with substantial investments in Ethereum. According to SEC filings, the fund, spearheaded by the PayPal co-founder, sold off half of its position. This move leaves Founders Fund with 2,547,001 shares of Bitmain. The sale raises questions about the fund's long-term outlook on Bitmain and, potentially, its view on the future of Ethereum. Bitmain's involvement in Ethereum mining and development means its stock performance is inherently tied to the cryptocurrency's success. While the exact reasons behind the sale remain undisclosed, market analysts speculate on factors ranging from profit-taking to a strategic shift in investment focus. The reduction in Founders Fund's stake could signal a change in sentiment toward either Bitmain or the broader Ethereum ecosystem. Investors will be watching closely to see how this development impacts both companies. ```
