In the cryptocurrency and US stock markets, mastering American macroeconomics is a must-have key.

Stay updated with key indicators such as GDP growth rate, Federal Reserve's interest rate policies, US Treasury dynamics, fluctuations in the dollar exchange rate, and the trend of the dollar index.

Also, consider the FOMC (Federal Open Market Committee) meeting resolutions and changes in the CPI (Consumer Price Index); all these factors influence the flow of funds and the ups and downs of financial cycles.

A deep understanding of these macroeconomic elements is like holding a navigation map, helping you accurately judge trends, respond flexibly, and seize every investment opportunity with ease in the complex and ever-changing environment of cryptocurrencies. Mastering macroeconomics allows you to navigate the market's turbulent seas!
