Spot always dominates the price trend in the long term, but short-term price or fluctuations in a large range are dominated by futures;

This does not mean that futures cannot be traded in the long term, but that there is less capital for long-term futures trading, and there is also less capital for short-term spot trading;

You can ask people around you, people who only do spot trading, the trading frequency is about once a week, while people who do futures trading can often do it 2-3 times a day;

So, when spot starts to sell continuously, within a few months, the price will not fall immediately, but will fluctuate up and down , but the highs and lows will slowly decline, because the supply of spot suppresses the maximum increase that futures can bring;
