After trading cryptocurrencies, I realized a principle, which is the concept of base currency. For example, are you using fiat currency as your base or BTC as your base? Because different bases lead to very different operational thinking. For instance, if BTC rises from 60,000 to 90,000, if it's a swing trade, you might have converted to fiat, but if you are using BTC as your base, you might actually be at a loss. Let me share an example with everyone:

"In 1935, the price of housing in Shanghai was 50 grams of gold per square meter; in 2024, the price of housing in Shanghai is 70 grams of gold per square meter. Gold is the eternal real money, and I believe BTC is too."
