Paper gold belongs to account gold, and there is no physical delivery. Individual banks can trade in both directions.

Physical gold is usually gold bars, jewelry and commemorative coins we buy in gold shops and banks.

Gold accumulation is to buy gold in the bank through a little accumulation, which can be cashed.

Gold futures belong to margin trading, that is, it has leverage and can expand itself, which is a two-way transaction. However, there is a trading time limit.
