You have said well but there is also something I want you to understand,
as a newbie to Bitcoin investment, learning about a secured wallet when you have not yet buy any Bitcoin is not a good move, the important thing is buy the Bitcoin first before any other thing, while waiting to know a good and reputable wallet to hold your Bitcoin you might have missed some good opportunities that won't come back again.
I kind of not agree with your perspective on newbies learning about a secured wallet, in fact, this should even be the first the very first thing to do because we are talking about where you are going to store your funds here and should be taking with priority, So to me, I believe it quite a very good move and even a wise thing to do for every beginner out there as this is one of the basic stuff we need know before kick-starting of our investment in digital world.
