F2Pool co-founder Wang Chun mentioned a "Silver Thursday" warning: He wondered what the market reaction would be if the CZ (China's central bank) restricted buying.

Wang Chun, co-founder of F2Pool, posted on the X platform that during the "Silver Thursday" of 1980, COMEX implemented a series of regulations that effectively prohibited new purchases of silver, allowing only liquidation and selling. He wondered how those spreading FUD sentiment in the market would react if CZ (China's largest silver trading platform) implemented similar measures. Silver Thursday was a major event in the silver commodity market on March 27, 1980. The Hunt brothers in Texas, USA, caused a silver price crash due to their failed manipulation of the silver market. The New York Mercantile Exchange introduced "Silver Rule 7" to address the brothers' hoarding activities. This new rule specifically targeted financial leverage, significantly restricting the use of margin to purchase commodities. Silver prices subsequently fell by more than 50% in just four days. Because the Hunt brothers had borrowed heavily to meet their silver purchase needs, they were unable to repay their debts, causing market panic.
