Bitcoin will now be classed as a commodity in the U.S. along with gold and oil, according to the Commodity Futures Trading Commission (CFTC), which has started to clamp down on unregistered firms that trade derivatives of the cryptocurrency.

The CFTC stated Thursday that it had ordered bitcoin options trading platform Coinflip, and its CEO Francisco Riordan, to cease trading due to it not registering and complying with its regulations. It added that it had also filed, and simultaneously settled, charges against the San Francisco-based firm.
