The traders that are active in futures trading, will participate in the market by being both long or short-term on futures contracts. They are mostly used by traders as a way to hedge other investments or to lock profits when trading in volatile markets. The futures contracts are mad made in an attempt to avoid market volatility.
Futures trading is a kind of bet. In other words, you are betting on the price movement of BTC that is parallel to the value of the contract without owning the asset.
