Citigroup (NYSE:C) is said to be awaiting regulatory approval to start trading CME bitcoin (BTC-USD) futures. Citi is recruiting people to join a crypto-focused team in London, according to a Coindesk report. Citi is expected to first trade CME bitcoin futures and then bitcoin exchange-traded notes. Last month, Coindesk reported that Bank of America (NYSE:BAC) will allow trading of bitcoin futures for some of its clients. In June, Goldman Sachs (NYSE:GS) began trading bitcoin futures with Mike Novogratz's crypto merchant bank, Galaxy Digital (OTCPK:BRPHF), in response to increasing pressure from clients who want bitcoin exposure, according to CNBC. Also in June, Citigroup launched a Digital Assets Group within its Wealth Management division and in May, Goldman formed a crypto trading desk.
