Cryptocurrency exchange Kraken has acquired British futures startup Crypto Facilities for more than $100 million. Kraken users can now trade spot and open positions for exposure to future prices. Crypto Facilities is registered with the UK's Financial Conduct Authority (FCA), opening up more markets for Kraken in Europe. The acquisition also gives Kraken access to CME's CF Bitcoin ($BTC) Reference Rate, an index for pricing U.S. futures offerings which Crypto Facilities and CME jointly worked on.
