There is only a crude oil futures fund, and there is no crude oil fund at all. There is a big difference between the two. Don't talk about crude oil funds in the future, say crude oil futures funds. For ordinary investors, the investment threshold of crude oil futures is very high. The threshold I said includes the threshold of funds and the threshold of professional knowledge requirements. Moreover, domestic crude oil futures still have serious problems such as non-24-hour trading, deviation from the international crude oil trend, and short-term trading being less active than the external market.
