I'm not on Twitter, so sorry. I think the best way to explain it is within the context of global markets. Cryptocurrency has all sorts of uses, because international trade and rapid market transactions require more fluid currency flow. It may seem like banks can handle it, but cryptocurency is a much more convenient option. There are also new "assets" being valued with technological innovation that challenge traditional methods of estimating dollar value. Cryptocurencies are here to stay.
