The whole fact about it all, is that everything we do concerns or requires a certain level of knowledge, it could aswell be that little which is rightly appropriate for a beginner, now going further the rest of knowledge goes with one's ability to remain consistent in the market. I think most especially the new investors are likely to make the right choices for themselves on how they understand even slightly on how the market operates, it could be on how much they choose to invest, when and what strategies to be implemented without having to blindly follow whatever they feel could be it, whereas we know that little mistake that could be made and it turns out to become a huge loss.
The only level of knowledge that is required here as an investor to start your Bitcoin journey is storage, security, risk and tolerance which in general are the process of starting an investment. When you eventually buy a little then you will understand that the rue knowledge comes when you have already get your investment kicking. Along the line you will understand what i mean. The good news is that there is a ton of information's out here for Bitcoin beginners. A lot of learning resources, articles and even here in this very forum can equip you with several knowledge from different enthusiast so that you can choose to make informed decisions from their opinions.
Your forgot to mention 'patience' because it is also one of the criteria that will enable you to be able to withstand the tough times when you feel like giving up due to some unforseen events that might occur in the future. Yes, as a beginner you shouldn't wait to acquire all the necessary knowledge before you start investing in Bitcoin because you may not actually understand the dynamics of investment until you have invested then you can seek the complete knowledge gradually however, a beginner should not only depend on the information they hear or come across online or just follow people that feels they are experts as there is need to DYOR so that you can have a backup with the information gotten from other people or sources. It is also good to know that investments are risky, therefore acquaint yourself with the right knowledge that will guide you through your accumulating stages but that should come after you must have started making your investments on Bitcoin.
