Bonds can't be speculated, they can only be bought and deposited, just like being deposited in a bank, but I'm afraid individuals can't buy bonds now. Futures is a forward transaction of commodities. For example, in June, we negotiated a batch of 10 tons of commodities, and we signed a contract. It will be delivered when it expires. Speculation in futures is speculation in contracts, not in commodities themselves. The content of the contract is standard and fixed, but there is no price. If you think you are going to fall, sell it; If you think it's going up, buy it.
