can someone who is not well educated (secondary school graduate) understand the statistics of bitcoin investment or Bitcoin trading?
What do you mean when you say "statistics".
Well, I will just disregard that word.
Anybody as long as he can read and write and has willingness to learn what is Bitcoin or cryptocurrency in general can invest or trade. This might be a different analogy, but it's almost the same. Just look at those businessmen today. Some of the didn't finish their studies, and yet, they are very successful now. They invested their time learning how to build a business, and now they are millionaires or billionaires now. As for you, you can also learn and gain knowledge and information that will help you in your Bitcoin investment and trading journey. What you just need is courage, willingness to learn, patience, and of course capital.

Investing has no borders. Whether you are a person coming from remote area or you're the poorest in your community. You can still invest as long as you are capable and knowledgeable enough.
