You know what op, I personally don't think paper money will completely disappear any time in the near future. It is true that electronic transactions have become more and more common over the last few decades and I see no reason why this trend will not continue. We may even get to the point where paper money transactions become incredibly rare. I mean, for some, they already are! we now consider paper money actually acting as the backing to our electronic currency, or the other way around? This get me confused a lot. But the thing is it is just like the way the gold standard once backed paper money. But that's just what i think. My own opinion
