Bitcoin: Investors whipsawed by digital currencies

The price of Bitcoin plunged more than 30 percent in a single day this week, then rebounded in a surprise rally, said Vildana Hajric in Bloomberg.com. Other cryptocurrencies also plummeted, including Ether and Dogecoin. The intense volatility, which at one point brought the total value of Bitcoin down $500 billion from its peak, shocked investors. “Nothing could explain the frantic rout” as Bitcoin “dropped thousands of dollars in price in a matter of minutes,” though a hint of restrictions from China’s central bank may have exacerbated the sell-off.
