Hold futures for up to one year. Because the delivery time of futures is generally one month, three months and one year, futures are based on a one-year cycle.

Futures and spot are completely different. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts with certain mass products such as cotton, soybeans and oil and financial assets such as stocks and bonds as the targets. Therefore, the subject matter can be commodities (such as gold, crude oil and agricultural products) or financial instruments.
