'Expensive' is a false concept, it's your irrational intuition. Intuition will tell you not to buy BTC or ETH if they are too expensive, not to buy gold if they are too expensive, and not to buy Nvidia if they are too expensive Rational investment should focus more on the future growth space, which is divided into two parts: the growth of intrinsic value and the process of value discovery, and the proliferation of fiat currency. The current market value of NVIDIA is 4 trillion yuan, and the first company in the US stock market to break through the trillion yuan mark was Apple in 2018. Is Nvidia really more valuable than Apple in 2018 at this time? I don't think so, the depreciation of fiat currency played a crucial role. As long as the foundation of modern economic theory remains intact, the depreciation rate of fiat currency will continue to rise exponentially. Investing in gold means buying "fiat currency continuously depreciates", investing in NVIDIA means buying "fiat currency continuously depreciates"+"self value", investing in BTC and ETH means buying "fiat currency continuously depreciates"+"self value"+the process of value discovery.
