BitMine Immersion Technologies Inc (AMEX: BMNR) saw its stock price soar by 15.47% in after-hours trading following the disclosure of a 9.1% stake by billionaire Peter Thiel. The stake, revealed by Thiel's Founders Fund Growth II Management in an SEC filing, has sparked significant investor interest. BitMine's recent shift to an Ethereum treasury strategy, with an accumulation of 163,142 ETH, has also contributed to the stock's rise. The company's market capitalization has surged from $25.86 million to approximately $2.12 billion. Additionally, the appointment of Tom Lee as chairman has further fueled market enthusiasm, as Lee has been actively discussing the company's strategy in media interviews. The trend of adopting Ethereum treasury strategies is also being followed by other companies like GameSquare Holdings and SharpLink Gaming, which have seen similar boosts in their stock performance.
