The above bolded phrase has just laid to rest a question I've pondered on for weeks as a result of an argument I had with a friend on this particular subject about 2 weeks ago.
He argued that it'll be a very wrong approach to split your attention into growing both your backup funds and your bitcoin portfolio,
I tried to make him see the possibility in building and developing one's backup funds while also building up one's portfolio but he was insistent that one must first build up their backup funds to its expected and required standard because beginning one's Bitcoin accumulation journey, even when/while I tried to make him see reasons with me, he refused so I gave up the argument.
Both are possible, it is just that since we have no way to control the events that happen around us, being too aggressive in our investment strategy can be very detrimental, if we find ourselves facing a difficult set of circumstances.
So the safest path is to build your emergency fund and only then begin to invest in bitcoin, however such an approach has an opportunity cost and you may miss buying bitcoin at an attractive price, so I can understand why you may prefer to take a hybrid approach.
