The U.S. Securities and Exchange Commission has denied a Freedom of Information Request on the BitConnect cryptocurrency investment scheme, citing an exemption usually applied to records tied to law enforcement. That said, Silver - who provided a copy of the newest letter to CoinDesk - said that he had been contacted by investigators from the Commodity Futures Trading Commission regarding BitConnect, interpreting that as evidence that an inquiry is underway at the U.S. commodities trade regulator. "As investors in cryptocurrency have begun to understand, where you invest and store your money is critical in this space."Here today, gone tomorrow" is a scary mantra, whether it be at exchanges like BitConnect, BitGrail, Kraken, or CoinCheck. As previously reported by CoinDesk, BitConnect was the subject of several cease-and-desist notices from U.S. state regulators, which cried foul ahead of a planned initial coin offering.
