I've been seriously planning my future recently and would like to hear everyone's advice.

Currently, the main questions I'm struggling with are:
Should I stay in the US or go back to China?
Should I focus more on traditional finance (investment banking, buy-side, quantitative finance) or continue to deepen my expertise in Crypto? Because I feel that crypto has really been diluted by AI.
What is the most worthwhile ability to develop during graduate school?
Are there any things that you think a 22-year-old absolutely must do?
Let me briefly introduce myself:
22 years old, Chinese
Just graduated from a US liberal arts college with a major in applied mathematics
Will soon attend Boston University for a Master's in Business Analytics
I've been trading stocks and cryptocurrencies since 2020, and it's currently my main research focus.
I've done some content creation on social media and also run my own trading community.
Recently, I've been interning in the corporate finance department of a bank, hoping to supplement my knowledge of the traditional financial system.
My long-term goal is to become an excellent investor and manage larger funds in the future. Actually, I'm not entirely sure.
Whether it's career advice, life advice, or any cognitive blind spots you think I might have, I will carefully read every reply.
