Cyberspace reported that cryptocurrency exchange Kraken has completed the acquisition of Commodity Futures Trading Commission (CFTC) registered futures broker NinjaTrader and reported a 19% year-on-year increase in first-quarter revenue to US$471.7 million. The acquisition of NinjaTrader will give Kraken's U.S. customers access the traditional derivatives market, in line with its plans to expand its product range and become the preferred platform for all types of transactions, which is believed to be the largest transaction to date between cryptocurrencies and traditional financial companies.
