Hehe, I can see at a glance that the landlord's understanding of futures is a bit incomplete. First of all, the most important function of derivatives is hedging; Secondly, each market has its own specific rules of the game; Finally, I think futures are for people who can take higher risks.

1. People who have a basic understanding of price trends (speculators: investors with high risk preference)

2. Enterprises that avoid risks; (Hedger: Investors whose risk preference belongs to aversion)

3. People between the first two (Arbitrator: risk preference is between the first two, and personally think it is also a group with stable profits in the futures market).
