1, yes, but rarely. Speculation in futures means high risks and high returns. If you only rely on speculating futures to support your family, it will be more difficult. If you are not careful, you will lose all the profits in the early stage, which is very risky. At present, there are very few people who can make stable profits in futures.

2. Futures is a kind of thing that is traded in the form of contracts, and the object of trading is mainly sales contracts. Futures are divided into commodity futures and stock futures. At present, there is no stock futures in China.

3. Futures are relative to spot. They have different delivery methods. Spot is cash spot, and futures are contract transactions, that is, mutual transfer of contracts. There is a time limit for futures delivery. Before the expiration, it is a contract transaction, but the expiration date is to cash the contract for spot delivery. Therefore, large futures institutions often do both spot and futures, which can be used for hedging and speculation. Ordinary investors often can't deliver in time, so they have to speculate purely, and the speculative value of commodities is often related to factors such as spot trend and duration of commodities.
