In terms of precious metals, spot gold is the best now. The dollar depreciated and gold rose sharply. If you haven't done it before, personally, I suggest you find someone who knows how to teach you how to get into the business. If it's too powerful, I guess you'll find it yourself and others won't pay attention to you. Now there is a Liu Ling, whom I have met twice before. Not bad, now in the component team, you can try. Maybe I can help you a lot and avoid detours. I hope to adopt.
