Two futures contracts will be listed: 1) A daily settlement bitcoin future, which will enable customers to transact in a same-day market. And 2) a monthly bitcoin futures contract will enable trading in the front month and across the forward pricing curve. Price formation in these benchmark contracts will be supported by proven tools to detect abusive or disruptive trading practices, including wash trades. That means that the settlement prices on ICE Futures U.S. will be based on prices discovered in our physical delivery contracts without relying on unregulated cash markets.
