The world's biggest exchange just joined the bitcoin revolution.
Bitcoin futures started trading Sunday night at CME Group Inc.'s venue, a week after Chicago rival Cboe Global Markets Inc. introduced similar derivatives on the volatile cryptocurrency. CME is a much bigger player in futures, so many traders expected it to make a bigger splash in the nascent space.
CME got off to a faster start with more efficient pricing. Its most-active contract changed hands 221 times in the first hour versus 570 during Cboe's debut. But that's a win because CME's contracts are five times more valuable — they're tied to five bitcoins compared with only one with Cboe's futures.
