MODERN CURRENCY: Here’s what’s next for bitcoin after the SEC killed the Winklevoss Bitcoin Trust.

The Securities and Exchange Commission on Friday rejected a proposed rule change that would’ve allowed for the creation of the first bitcoin exchange-traded fund—a decision that has followers of the world’s largest cryptocurrency wondering what happens next.

In its ruling, the SEC said it was unnerved by the lack of regulation in a market that is largely based outside of the U.S., and was worried about the potential for market manipulation.

Fortunately for investors who were hoping to buy into the fund, Friday’s decision won’t necessarily preclude the approval of other proposed bitcoin ETFs. Two other companies are vying to become the first bitcoin-focused ETF, but what might happen next is unclear.

John Galt’s “Get the hell out of my way!” remains relevant.
