Yes of cause you don't need to know everything about investment before you start investing
It's a process of learning, you can start with a little amount of money first then as time goes on as you begin to learn more about the investment you can be invest a larger amount of money
But before any one starts at least they should know the basic things about the coin like but at the dip and hold
But just starting without knowing any thing concerning the coin is just gambling.
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, then along the line you might start learning more on it and what is required, like what you have to do to be successful on the longer term, but the problem I have with this your post is you addressing Bitcoin as a coin, because by doing so, most newbies will start thinking that they can invest in anything in the market, not knowing that it's Bitcoin you are talking about, not alt or meme coin, so try to be specific when talking about Bitcoin in case of next time, in other not to mislead newbies in the space.
