Interesting thoughts, I believe that over time the paper money will become obsolete. The convenience of electronic payment systems brings great market opportunities ahead.
It is a pity that paper moneyight become obsolete with time buy it has its own conciniency. Electronic currencies depend on technology which can fail at one time. Imagine a situation where there is total lack of internet even for just 5 minutes. I bet trillions will be lost over the world.
What do you mean by trillions lost? No money will be lost even if there is a total blackout, not just some internet connection severed. A few monies may not get earned, indeed, but certainly not in the range of trillions unless there is no more electricity for good (just like in the Revolution movie series). Beside that, digital currencies started off decades before Internet...
The technology behind electronic funds transfer (wire transfer) had been developed in the late 1950s - early 1960s
