But if you "know what you're doing" and quite sure about things, then getting loans and throwing them into encrypted currency isn't always the worst idea.
This is true but might not come in handy all the time. No matter how much we know about what we are doing and where we are investing things cannot go always on our side, there is still a chance that you will lose. I still don't think that borrowing money just to invest in anything not just in cryptocurrency because investing has no certainty that you will profit in the end.
