My question is can someone who is not well educated (secondary school graduate) understand the statistics of bitcoin investment or Bitcoin trading?
Good question.
Certainly, even someone with limited education can learn the fundamentals of Bitcoin with enough work and research. While having a background in computer science or finance may be advantageous, it is not necessary to grasp the underlying ideas behind Bitcoin. I am currently studying a program not related to any of it. Just give some time and you'll learn. However, it's important to remember that understanding Bitcoin trading requires having a foundational understanding of financial principles like supply and demand, market patterns, and risk management.
