I am not sure, but it suggested me to use a custom multisig setup, which is good because it's not far from the reality. Of course I am not using this system only, but it's certainly a good thing that the quiz suggested me to do what I already do. It has some accuracy.

It's a good endeavour, don't get me wrong, but I can't think as a beginner very easily, because I 've already gone deep inside the rabbit hole. Perhaps some other users who think they are "beginners", could give a better answer.
