Investing in those who have potential now is not expensive now, but will be valuable in the future. Relatively speaking, rare metals are good. According to statistics, most rare metals in the future are scarce and non-renewable. At present, they are 10 times lower than gold prices, but only 10% of gold reserves. Please refer to the golden 008 net. Buffett recently invested 500 million rare metals in the stock market, which deserves attention! It shows that the investment you are asking about is really hot and continues to heat up, which is an inevitable trend.
