Opening an account for spot crude oil is free. How much money you need to activate after opening an account depends on the platform. Some platforms have thresholds for opening accounts, while others have no thresholds. If you want to do it, it is suggested that the fund should not be too small, and the risk is relatively large.
Some member companies and agents will set a general threshold of 2-5W, but the more funds, the lower the risk, because spot crude oil is a margin trading system with leverage. The minimum investment only needs to meet the quantity of operators.
