Gary Gensler, chairman of the U.S. Securities and Exchange Commission (SEC), tweeted that “cryptocurrency trading platforms must comply with regulations, register with the SEC, and deal with conflicts of interest. Cryptocurrency trading platforms must treat cryptocurrencies like securities, and platforms must stop acting as if the law is ambiguous. If you are a stock exchange, clearinghouse, broker or dealer, you must comply with regulations, register with us, deal with conflicts of interest and disclose important information.”
