As a beginner that wants to significantly grow his knowledge about BTC in particular and cryptocurrency in general so as to be able to make meaningful contributions to the forum, which of the boards and threads am I expected to regularly visit and read about them in the forum please
OP it is good you are asking questions to learn more about the forum but your question is like asking people where you can get water when you are in a river. This forum is an information bank of Bitcoin and other cryptocurrencies. Some members have directed you to some sections of the forum that basically deals with your request but you can also get bitcoin knowledge in some other sections.
The economic section of the forum exposes you to how national economic policies affect bitcoin. I also find the political section interesting because sometimes members expose us to the relationship between national politics and the political space of the nations. Apart from learning about bitcoin the forum also teach basic morale that can be helpful so visit other sections for this information. I think it is now time for you to explore the forum and gather a lot of information.
