Private investment platform Linqto has filed for Chapter 11 bankruptcy protection in the U.S. District Court for the Southern District of Texas. The company holds approximately 4.70 million shares of Ripple in the secondary market, with an estimated value of up to $450.00 million, but Ripple states that it has no business relationship with them. According to court documents, Linqto holds over $500.00 million in private securities assets through its investment vehicle, Liquidshares. The company closed its platform and terminated its revenue streams as early as March. [Cointelegraph]
