Technical vs. Fundamental: Don't Mix Them Up
Many focus on technical analysis (charting) and ignore fundamental analysis. I see the opposite:
Technical analysis is good for short-term timing (like day trading).
Fundamental analysis is what determines if a currency will survive in the long term.
Example: In 2021, technical analysis indicated that Bitcoin would rise, but due to the volatility of the Federal Reserve, the market collapsed. Here, an understanding of macroeconomics would have saved you.
