BitMine Chairman Tom Lee sees a crypto buying opportunity as investors reduce risk in the US, South Korea and Taiwan. The KOSPI fell 17% in October through October 16, while Ethereum fell 1.91% over seven days. Lee argues that falling prices have historically offered attractive opportunities when fundamentals remain strong. BitMine holds Ethereum as its treasury asset, and Ethereum has fallen further from its peak than Bitcoin. However, Lee's buying case needs interest rates to ease as well as fundamentals to hold.
