Peter Thiel exited his 7.5% stake in Ethereum treasury firm ETHZilla following a nearly 98% drop in the firm's share price since its peak last year. ETHZilla shares fell significantly more than Ethereum itself, which dropped about 61% from its all-time high. The company has responded with stock buybacks, splits, and diversification projects, but Thiel and his Founders Fund also reduced holdings in another Ethereum treasury firm, BitMine Immersion Technologies.
