Futures contracts have a delivery period, usually the longest contract does not exceed one year. During the delivery period, you can make delivery or close your position before the expiration. So it is impossible to hold positions for a long time.

In addition, futures are margin transactions, usually the margin is 5%- 10% of the contract value. In this case, if the futures price doubles, its margin will increase by 10-20 times, and how much money you have is unbearable.

Futures should be fast-forward and fast-out, especially for retail investors. If we operate futures according to the idea of doing stocks, it can only come to a bad end.
