You can aswell get those proper knowledge when you have already started buying bitcoin because i believe you will know more when you are into proper with your little knowledge at first, bitcoin investment is not too hard to know as people may think first thing is to get started when your Discretionary income is ready to avoid procastinating while trying to gain proper knowledge.
It's not too hard, yet people may be inclined to drop their bags even if they see even a bit of red.
To avoid this, knowledge should be built up beforehand.
Building up bitcoin knowledge before you start investing in bitcoin will not even save you from not selling off your bitcoin portfolio if there's a dump in bitcoin price. Even old investors who have built up knowledge about bitcoin ended up selling off their bitcoin portfolio before a dump could happen because they invested in bitcoin in the wrong way or aggressively, which put them in the position of not meeting up with their daily demands all the time. So even though you have good knowledge about bitcoin or not, before you start to invest in bitcoin, if you want to hold your bitcoin portfolio for a very long term, you have to invest in bitcoin in such a way that it will not stop you from sorting out your daily expenses all the time, and for you to do that, you have to use your discretionary income or the money you can afford to lose to invest in bitcoin since the money is not allocated to solve any of your daily expenses.
