History

Historical Context

In February 2014, Mt. Gox, then handling over 70 % of global Bitcoin trades, filed for bankruptcy after losing about 850,000 bitcoins—roughly 7 % of all supply and valued at $460 million. The collapse spurred Japan’s first crypto-exchange regulations and heightened U.S. oversight. In 2026, Polymarket’s $10 million debit-card fraud scheme prompted the CFTC and SEC to scrutinize its $21 billion valuation.
