It's trivial to say in hindsight "if you had just bought XYZ in January you would have 80% gains by now!". Yet this is pure confirmation bias. Moreover, surveys routinely show that amateur day traders do not consistently beat a global stock index in a statistically significant manner.

Extrapolating from past data with N=1 to demonstrate that "any tech person can outperform the index" shows a crass lack of mathematical reasoning, which in my opinion demonstrates why you're unsuited to professional trading.
