Bitcoin could be on the verge of breaking through as a mainstream currency. At least that’s the goal of a startup that is soon to be launched by one of the most powerful players on Wall Street, with backing from some of America’s leading companies. This morning the Intercontinental Exchange—the trading colossus that owns the New York Stock Exchange and other global marketplaces—announced that it is forming a new company called Bakkt. The new venture, which is expected to launch in November, will offer a federally regulated market for Bitcoin.
