Not only in the world of bitcoin investment, but in every profession, every area of life... before you want to do something, you need to be trained and educated. Do you see any jobs that do not require knowledge and education? Even workers and manual laborers need basic knowledge, the importance of education is undeniable and everyone is aware of it.
I have not seen anyone who can be successful if he or she does not have the education and knowledge of the field that helped them succeed. Bitcoin is an investment and you need a lot of knowledge to win, it's not gambling where you just rely on luck to win.
