TechFlow news: On February 6, Wang Chun, co-founder of F2Pool, posted on X stating that during the “Silver Thursday” event of 1980, COMEX implemented restrictive measures—effectively banning new silver long positions while permitting only liquidation and short-selling transactions. He added that he is curious how market participants spreading FUD would react if Binance founder CZ adopted similar measures.
Public records indicate that “Silver Thursday” was a major incident in the silver commodity market, during which the New York Mercantile Exchange (NYMEX) introduced “Rule 7 for Silver,” drastically restricting the use of margin to purchase commodities; subsequently, silver prices plummeted by over 50% within just four days.
