Action against Defendants, a diamond company, an investment company, a cryptocurrency platform, and three of their owners and executives, for an alleged Ponzi scheme.  According to the SEC, Defendants offered investment opportunities in diamond sales and a diamond-backed cryptocurrency that they claimed was risk free.  The SEC alleges that Defendants instead misappropriated these funds to pay other investors and for their own personal expenses.
