If you want to gain knowledge about everything related to Bitcoin, then that's fine. But you don't need to know all of this to own Bitcoin or hodl Bitcoin. The most important thing for a Bitcoiner who invests in Bitcoin is to understand wallet security, to know the best wallet to use for hodling Bitcoin, and to understand the volatility of Bitcoin. If you have this understanding, investing in Bitcoin won't be a problem. As a beginner, don't think you need to know everything about Bitcoin before investing.
Bitcoin is actually broad that you can want to learn everything about it and end at becoming a master of none. It is most beneficial to focus on getting a mastery of a particular area and knowing how you can be using the knowledge from it to making profit from it. Even in the technical aspect there are branches of knowledge within it, and so it is with the non-technical aspects. The error that most beginners make is in the thinking that you've to know everything before you can excel.
