Everything depends on the level of your understanding but if you ask me, I think you don't need a particular time to understand things on the Bitcoin discussion rather your activeness and your determination to learn, read and understand the things you read daily determines how much time it will take you to be able to know how to communicate effectively on the discussions on the board. There are other boards in the forum you should also visit so as to have a broad knowledge of Bitcoin and other cryptocurrency all you need is to always stay active and pay attention to the informations you see here by doing just that you will learn and become a good forum user and your understanding will be enlightened also.
