Tom Lee, chairman of BitMine, has issued a warning against the use of leverage amid the current crypto market downturn. He highlighted that the downturn has revealed significant balance sheet vulnerabilities in some market makers and the presence of predatory actors causing Bitcoin price crashes. Despite these challenges, Lee remains optimistic, asserting that these issues are temporary and will not derail Wall Street's objective of establishing an Ethereum super cycle. He anticipates that resolving the balance sheet problems could take 6-8 weeks.
