Paper gold: transaction is a service provided by banks, without the intervention of real money and silver. Investors don't need to buy or sell physical objects, but invest in gold by bookkeeping. It is worth noting that although it can be equated with holding gold, the "gold" in the account cannot be exchanged for physical objects, and the "deposit" has no interest.
Spot gold: Spot gold (also known as international spot gold and London gold) is a spot transaction, which refers to delivery after the transaction is completed or within a few days.
Gold futures: Futures refers to the standardized contract made by the futures exchange, which promises to deliver a certain amount of subject matter at a specific time and place in the future. Gold futures are futures contracts of spot gold.
The difference between the above three products can be simply summarized as paper gold has a large principal and no leverage; Gold futures trading time is short (5 hours) and leverage ratio is low. Spot gold makes up for all these shortcomings. I suggest that you can do spot gold margin trading to make up for all the shortcomings of paper gold.
