As for the investment in gold and silver, I can tell you that the most suitable investment platform in China is the futures market, because its leverage is reasonable, generally between 6 and 8 times (see the margin ratio of futures companies that open accounts is stipulated by risks). At present, it has withdrawn from the night market (the term covers the active period of precious metals, which fully meets the daily investment needs), and the fees are low (only the transaction fee is very low, and it is charged unilaterally within the day). The only drawback is probably that the amount of a single contract is relatively large.
Spot gold is London gold. At present, it can only be done in China through some Hong Kong agent platforms, which is expensive, with a regulatory vacuum and high risks. Advantages are 24-hour trading, greater leverage, and the amount of a single contract is smaller than that of futures contracts.
As for the so-called spot precious metal platform that you usually see, it can be collectively called precious metal electronic disk. Generally, some companies with spot precious metal trading background extend some electronic trading on the spot basis, but the scale of general trading is much larger than their own funds and spot stock, but the supervision is in a vacuum, which leads to the proliferation of precious metal platforms at present, whether it is a platform company with a certain strength in spot background or some electronic disk platforms made out of thin air. They all made a quasi-spot trading platform, and they made a pool of funds to play, which led to a regulatory vacuum. Finally, when the capital chain breaks, it may be a Ponzi scheme, and such platforms generally have high handling fees and high spreads. In the end, it is the platform and agents who make money, and even large retail investors who may make money with agents.
Generally speaking, for retail investors and institutions seeking long-term development by technology, futures are the most sensible choice.
