I totally agree with you because Bitcoin doesn't need too much or too many knowledge before one can start because you don't need or have to study the market or predict it like traders, which can be very stressful and time consuming, I think all a beginner need to start is knowing what is discretionary, emergency and reserve funds and have them place then how to buy and hold and anyone who went for more knowledge about Bitcoin investment before starting will not only waste time and opportunity but will also realize later while investing that those knowledge wasn't really necessary and anyone who have already experience this should not get discourage but rather keep on pushing.
If people start with investment mindset and plan for it, they will have a lot of time for learning more about Bitcoin after their purchases. Bitcoin is here and won't disappear, so after purchasing bitcoins for their investment portfolios, they are free to dig deeper and learn more about Bitcoin with many free and available resources.
It's always true that if they have more knowledge about Bitcoin from its technology to market cycle history, they will have stronger hands for holding bitcoins. So with a lot of time to use for learning, they need to use their time properly for enhancing their knowledge as well as strengthen their hands that together contribute to their investment success.
Of course, bitcoin knowledge is so broad that,, you will continue learning as long as you are investing because yiu have made bitcoin part of your life since we hopw to reap from the fruit of our labor in future. Also, it is not only to be learning as you are investing, you should also looking for a means of increasing your income so that you can have more flexibility in your bitcoin accumulation journey and invest aggressively when you can.
