Just because it's cool and we can call it electronic cash? What's the point? Why would you bother building it? Why would anyone bother using it?

Ah, to make money off it of course! Advertize it, and people will use it. Maybe. For a time. And when it wears off, you launch another one. Sure, it's pointless technically, but so are many gimmicks that are commercially viable, if only for a limited time. And maybe the LEAs are actually even pushing it as a way to easily catch clueless criminals :) -- Vincent Penquerc'h
