As a new investor I don't think it requires much knowledge.
(Though the saying goes that knowledge is king)
But once you go to the market, you can learn all kinds of things by yourself.
as someone that is new to the system, the first thing you should know is that you need to Buy the DIP.
I disagree to what you said that you don't need much knowledge before you invest, how can you know the DIP when you don't have the required knowledge? see you have to know that havng knowledge and having the right knowledge are two different thing, because buying might be easy but holding can be very difficult if you don't have the right knowledge on all that is required of you, so that you can weather the storm and hold without touching it even when you are seriously in need, In all we do in this life, knowledge is very important, because if you have the right knowledge, you will definitely know that you need another source of income and an emergency fund that would sustain you, not to touch your Bitcoin holdings.
