Digital Currency Group (DCG), the parent company of CoinDesk is closing down its trade execution and prime brokerage services unit, TradeBlock, citing crypto winter and regulatory uncertainties. The shutdown of the unit, which provides trading services to institutional investors, will be effective as of May 31, a DCG spokesperson told CoinDesk. TradeBlock was acquired in 2020 by CoinDesk, and was later spun out as its own standalone business. CoinDesk kept the index data operating from the deal, which was rebranded as CoinDesk Indices, and “has proven to be a successful acquisition,” the spokesperson said. The story was first reported by Bloomberg.
