Bitcoin Futures are an agreement to buy or sell an asset on a specific future date at a specific price. Either a long position, where you agree to buy an asset in the future at a specific price when the contract expires. Or when you take a short position, you agree to sell an asset at a set price when the contract expires.
Bitcoin Futures are listed on Chicago Board Options Exchange (CBOE).
