For those who are new to bitcoin investing, I must say that before investing in bitcoins, you need to acquire enough knowledge about bitcoins.
Like I already mentioned in as much as getting knowledge about something or investment is very good but when we talk about Bitcoin is actually exempted from every other investment that requires so much knowledge before you can start operating on them so actually in terms of Bitcoin everything such as investment is made very easy to start investment without have to read so much book and watching YouTube videos just learn about it before going into it, for me I consider Bitcoin investment in terms of knowledge as a very flexible investment because as a beginner the more you are investing in Bitcoin that is how you are also learning and understanding more things about it. So let's not always sees knowledge as some sorts of mandatory thing that must be done before starting your Bitcoin journey.
However below is a good Clarification and explanation made by @JayJuanGee concerning this knowledge people are so much emphasizing on, so you can read through to understand more about it.
I doubt that anyone who is brand new to bitcoin needs to get too worked up about his/her entry point, especially since the presumption would be that someone who is brand new to bitcoin does not have any bitcoin, so therefore getting started would mean getting started by starting to buy bitcoin and perhaps figuring out some personal financial and psychological aspects rather than trying to figure out things related to BTC price moves or maybe even trying to figure out more technical aspects of bitcoin. Surely it can take people a decently long time to learn about bitcoin, so maybe to get started there might need to be some kind of initial belief that bitcoin is a good investment.. yet I have my doubts about that too.. since anyone should be able to adjust the size of his/her initial investment into bitcoin based on not having much knowledge and/or confidence in the beginning, yet learning more about bitcoin along the way so then as knowledge increases, more comfort might come towards investing more into bitcoin..
