BlockFi blamed its chapter 11 filing on the downturn in cryptocurrency prices this summer and this month’s failure of FTX. FTX’s affiliated trading firm, Alameda Research, defaulted on $680m owed to BlockFi earlier this month, the firm disclosed in court papers. Bankruptcy gives BlockFi a chance to formulate a repayment plan for creditors and get back what it can from FTX, though any potential recoveries are a long way off.
