I feel like at first when you are really new to bitcoin and you have absolutely no idea about it, you should spend 2 to 3 hours a day to research the basics and the core function of bitcoin and how it works, but once you got all the basic things out of the way you should be getting less time into it because you won't find new things like you were at the start, and if you are an active member on this forum you should be able to lean new things every now and then from topics and other people's posts.
