Interesting article. The comparison of bitcoin as the Kleenex of crypto currencies is keen and will probably hold true that better technologies will catch on, but I am old enough to remember the period of ancient history known as the 80s. And this is getting really getting deep into the field of archeology, but there used to be two versions of video cassette (beta and VHS). Beta was much better technology, but VHS was the Kleenex version and Beta just died off. Yes, I know VHS died out too, but it did have its day in the sun.
