Your idea is right. Futures can only make money for a long time. Make a lot of money. The way is to look at the trend. Long-term holding after buying a contract. Rather than being moved by short-term fluctuations. However, it should be noted that if the trend is wrong, you must stop the loss in time! This is the key! Make it profitable. For example, after the gold crash last year (that is, when Chinese aunts robbed gold). Personally, I think the long-term trend of gold is empty. After a short rebound, the international gold price opened an empty order near 1400, which has been held ever since. Of course, there is a shift in this. But it is basically always held.
