First, compared with crude oil investment, the trading method is flexible and the capital utilization efficiency is high;

China investors are undoubtedly familiar with the diversity of capital market transactions. The unique T+ 1 trading mechanism in China stock market makes the operation of stocks very difficult and inflexible. T+0 trading mechanism of crude oil investment is easy to grasp the market at any time, avoid risks and has strong operational flexibility.

Second, compared with futures, it has a perfect market mechanism and flexible trading hours;

Compared with futures investment closely related to crude oil investment, the trading time of futures is mainly concentrated in daytime working hours, and the trading of crude oil investment is mainly concentrated in Europe and America, so the active trading time is mainly concentrated at 8:00- 1 1:00 in the evening, which is a good staggered working hours and convenient for centralized operation.

Third, compared with precious metals, hedging has irreplaceable investment needs;

Compared with precious metals with high domestic investment in recent years, the practical use of precious metals is mainly used in jewelry technology, medical equipment and storage. Compared with crude oil, the market demand for precious metals is not high, but crude oil, as an industrial raw material, is widely used in various industrial production and processing, which has a national strategic position, and its spot market demand is stronger than that of silver, so investors have a greater demand for hedging by combining spot and futures, which well reflects one of the advantages of crude oil compared with silver-hedging.

Fourth, compared with real estate, the investment profit margin is larger, the threshold is lower, and the investment recovery cycle is faster.

Compared with the crude oil investment and the real estate industry, which had the biggest investment income in previous years, the real estate industry started a wave of excellent investment market in 2006. However, at present, the government's enthusiasm for market investment in various purchase restrictions has decreased, and there is a big bubble and potential risks. Secondly, the real estate industry has a high investment threshold, which is beyond the reach of ordinary retail investors. Real estate investment has a long payback period and slow capital withdrawal. However, the price of crude oil fluctuates greatly, coupled with its two-way trading mode, there are more investment opportunities, the trading threshold of using margin is low, the investment demand of small and medium-sized investment is met, and the investment return period is short.
