You didn't mentioned what you wanted to learn. In any case though, crypto sphere is vast and massive and it's really hard to grasp everything in on sitting. I guess it's really up to you to get the knowledge by doing your own research and investigation about what subject you wanted to learn. And just remember that in crypto it's a marathon, not a race. So it's going to be a long journey, but just take one step at a time and don't rush things up. And as you have said, this community is great, so tap it, used the search function and if you have a question then you can create a thread.
This is why it is important to be realistic about what we can achieve in the markets, those thinking that will make a fortune in just a few weeks with bitcoin are susceptible to this mistake, when the reality is that even people that have been here for years are still learning something new every day due to how deep the knowledge surrounding the market of bitcoin really is.
