Whether investors' funds can be safe depends on the platform chosen by customers to some extent. At present, the trading of London gold is mostly stopped through the online trading platform, which provides great convenience for investors and brings great risks. Network information is mixed, and it is easier to fall into the trap of false platforms. Therefore, for investors, where to open a London gold account is a relatively safe issue. As far as domestic investors are concerned, there are two main types, one is to open an account in the mainland, and the other is to choose a trading platform in Hong Kong. Among them, the history of London gold trading in Hong Kong has become longer and the relevant systems have become more perfect, thus attracting a large number of mainland investors. The choice in Chinese mainland should be centered on Shanghai Gold Exchange and Shanghai Futures Exchange, both of which are precious metal trading places approved by the State Council, and their legality has been fully guaranteed. Therefore, when choosing relevant places, we should pay attention to whether they can have business qualifications. Shanghai itself is also one of the internationally renowned financial centers, and it is also the general trend to start trading precious metals.
