I don't think one need to go this deep before starting his bitcoin journey (investing in bitcoin), just having th basic knowledge, and how one can secure his asset he or she is good to go . Because the time one is taking to focus on accumulating knowledge alone when he or she should also be accumulating bitcoin, may lead to one missing out big time. Because the price wait for nobody now alot of folks are even saying that Bitcoin is too expensive, but as time goes Bitcoin will get to a point where people will refer this recent price as when bitcoin was cheap.
So as one is learning about Bitcoin, expecially in this forum is advisable that he or she is also accumulating Bitcoin or holding some stashes of Bitcoin while learning more about Bitcoin, so that as Bitcoin continue to surge In price your stash will also surge with it.
Exactly what one should know is: what bitcoin is, how to receive and send out bitcoin, the type of wallet, and the difference between an exchange account and a noncustodial wallet.
At least for the person's safety, the more the person gets involved in bitcoin and carries out activities, the more he or she will easily expand their knowledge. They can't learn everything one day or all at once; it's something that comes with experience, practice, and research too.
