The CEO of bitcoin exchange #Coinbase, Brian Armstrong, stressed that regulating #cryptocurrencies is not "rocket science" and expressed optimism that the United States will eventually reach regulatory certainty, "even if it takes a while."

A few days after the U.S. Securities and Exchange Commission (#SEC ) sued Coinbase on June 6, #Armstrong agreed to an interview with The Wall Street Journal on June 11. According to the SEC, Coinbase has been running a broker-dealer, clearing house, and securities exchange without being registered with the agency.
