No offense, but that BLITZ logo doesn't look like anything an adult would take seriously at all. It makes Monopoly money look mature and dignified. Cool, yes. The same way Optimus Prime is cool. Not as a currency.

IF you want to go goofy, you go Roto/DOGE route and play it to the hilt. Something that's been marketed like ZEIT has so far probably shouldn't take that route.
