SEC chairman says he doesn’t see bitcoin trading on a major exchange until it is ‘better regulated’

“If [investors] think there’s the same rigor around that

Stock Exchange ... they are sorely mistaken,” said Clayton, the opening speaker at the Delivering Alpha conference,
presented by CNBC and Institutional Investor. “We have to get to a place where we can be confident that trading is
better regulated.”
