The so-called gold futures refer to futures contracts with the gold price of the international gold market as the trading target at a certain time in the future. The profit and loss of investors buying and selling gold futures is measured by the difference between entry and exit, which is the physical delivery after the contract expires.
Spot gold refers to physical delivery, such as gold bars and coins. Spot gold is only a virtual book transaction, without physical delivery. How many grams of gold are there in your passbook? It's just a bookkeeping symbol, and you can't extract physical gold. It just earns the difference by buying and selling.
