Cryptocurrency futures are contracts that enable traders to speculate on the potential price of a cryptocurrency, while the underlying spot market is the actual market where the cryptocurrency is traded. The relationship between the two is that the futures market is utilized to prognosticate on the future cost of the cryptocurrency, while the spot market is used to purchase and sell the actual cryptocurrency. Bitcoineer provides a selection of cryptocurrency futures, including Bitcoin, Ethereum, Litecoin, and Ripple, allowing users to diversify their trading portfolio and capitalize on various market opportunities.
