NEW YORK – Even by Bitcoin's standards, Wednesday was pretty wild. The price of the famously volatile digital currency fell nearly 30% at one point after the China Banking Association warned member banks of the risks associated with digital currencies. The decline narrowed to below 10% in the afternoon, but Bitcoin had still lost about $70 billion in market value in 24 hours.
