A former affiliate of BitConnect, Satish Kumbhani, accused of a $2.4 billion Ponzi scheme in the U.S. last week, has fled his native India, authorities said.A lawsuit has been filed separately by the Securities and Exchange Commission against Kumbhani, alleging that he raised more than $2 billion fraudulently from investors in his cryptocurrency exchange platform. However, the SEC does not know where Kumbhani is and could not serve him. During the week, the mystery deepened. SEC attorney Richard Primoff wrote in a court filing that Kumbhani, 36, has likely moved out of India to an unknown address in a foreign country. Since November, the SEC has been contacting the country's financial regulatory authorities to learn Kumbhani's location, but the location remains a mystery.
