I don't know, maybe it is possible for someone to be an expert about Bitcoin becaus Bitcoin knowledge is wide. What I would advise you is to choose one path, whether you want to know more about Bitcoin investment, trading or mining. Also, there are technical aspects of Bitcoin, so I would just advise you to focus on one area mostly. You can be learning from other aspects, but it's good for you to focus mainly on one or two so that you can learn deeply easily.

For example, what I focus most on is Bitcoin investment, so I focus on learning more about Bitcoin investment, such as understanding the best strategies for accumulation and also learn how to provide proper security for my Bitcoin investments. I can see that some members have provided you with links, it be a great benefit if you go through them properly. Also, try to always go through discussions that others memeber are engaging so you can continue learning from them.
