Physical gold paper gold can be bought and sold in major banks, and so can online banking.
Futures gold can only be traded on the Shanghai Futures Exchange. You have to open a futures account, find a cost-effective futures company, bring your ID card and bank card, and go to the futures company to open an account. Then download the trading software of the futures company where you open an account and transfer it to the fund, just like buying and selling stocks. The difference is that futures gold can be traded at t+0, and it can be traded indefinitely on a good day, but the risk is relatively high, and the leverage is amplified by 8 times.
Spot gold requires higher capital, and few people generally play with spot gold.
