CME Group’s launch of Bitcoin futures makes it “legit,” the mainstream press reports after the virtual currency hit Wall Street Tuesday.

Describing the impact of the world’s largest exchange owner offering futures trading by the end of 2017, Bloomberg said the “floodgates have been opened.”

“Bitcoin is going legit, for better or worse,” it writes today.

The move is an unexpected one, coming soon after CME said it had no plans to launch Bitcoin integration last month.
