Billionaire investor and former PayPal CEO, Peter Thiel, has acquired a 9.1% stake in Bitmain Immersion Technologies, a publicly listed Bitcoin mining firm. Interestingly, Bitmain recently announced an Ethereum (ETH) acquisition strategy, revealing a substantial holding of 163,142 ETH, currently valued at approximately $500 million. This investment effectively provides Thiel with indirect exposure to Ethereum. While the primary focus of Bitmain has traditionally been Bitcoin mining, their foray into ETH holdings suggests a diversification strategy, potentially driven by the growth and development of the Ethereum ecosystem, including DeFi and NFTs. Thiel's investment reflects growing institutional interest in both Bitcoin and Ethereum. The markets have responded positively, signalling confidence in Bitmain and its investment direction. ```
