Bitcoin suffers worst day since its debut on Wall Street, down 8%

Bitcoin futures were under selling pressure on Wednesday as the digital currency, which has captured the attention of Wall Street and Main street alike, was down sharply and facing its worst day in its short period on futures markets. The January contract trading on the Cboe Global Market Inc. since Sunday was down more than 10% in recent trade at $16,190, which triggers a 2-minute pause in trade according to the exchange's trading rules. The move for the digital asset comes as Interactive Brokers Group Inc., said it would allow investors to bet against, or short, bitcoin. Bitcoin futures trading halts for 5 minutes after a 20% drop.
