There are two purposes of futures investment: one is to avoid the risk of price fluctuation, and the other is to earn profits through the bid-ask difference.

Its investment methods can be divided into three categories: hedging, speculation and arbitrage. The purpose of hedgers is to avoid the risk of price fluctuation, while speculators bear the risk of price fluctuation and earn profits through price fluctuation. Arbitrators have relatively low costs and risks, but they also want to make profits.
