Bitcoin Euro and Ether Euro futures contracts will be sized at five bitcoin and 50 ether per contract. These new contracts will be cash-settled, based on the CME CF Bitcoin-Euro Reference Rate and CME CF Ether-Euro Reference Rate, which serve as once-a-day reference rates of the euro-denominated price of bitcoin and ether.
