Digital Currency Group (DCG) missed a $630 million payment owed to Gemini last week, according to crypto exchange Gemini. Gemini CEO Cameron Winklevoss had previously threatened to sue DCG CEO Barry Silbert and DCG over the repayment of a $900 million loanafter Genesis, a DCG entity, filed for Chapter 11 bankruptcy in January. The U.S. Securities and Exchange Commission has accused both firms of selling unregistered securities through their Earn program. Both Genesis and CoinDesk are owned by DCG. Gemini and other parties are proposing an amended reorganization plan with Genesis that doesn’t require DCG’s approval, Gemini said in an update on its site.
