Looking at this your post here and all you said here, you are not entirely wrong, what you are trying to say makes sense to me, because you must not have it all to start your Bitcoin investment, all you just need is the basic knowledge of it and how to go about your Bitcoin accumulation,
You don't need to know much before investing in Bitcoin. Rather, after investing, an investor learns everything step by step. Just as you can't learn to swim by reading books, you can't learn about investing without investing. But yes, you can get basic knowledge.
An investor should always start. And until he starts, he will continue to struggle.
Find out the main purpose of investing. Why and for what are you investing. How many years do you want to keep your investment.
Emergency fund and other tasks, such as prudent income and backup fund allocation.
Confidence will be effective for you before investing. You don't need to know anything extraordinary about investing.
Only long-term investments should be made. Less than 10 years, long-term investments are profitable in the long run.
I totally agree with you on the fact that practical engagement in a thing is a more faster way to know about that thing. However, I will advice some degree of financial independence before investing. It is no news that Bitcoin possesses some degree of volatility and this volatility can be best tackled and understood if you ain't investing all your revenue in Bitcoin.... You will invest without emotions and have a clearer picture of the chart
