Personally, with the team behind it, and the general principle behind it being for it to be a "used daily" coin. It should have been called simply "Credits" (yes I know there is a "CreditCoin"). But 50,000 Sci-fi movies can't be wrong. "instant" name recognition... Sci-fi fans around the globe would buy, and use it just for the name...hahaha
Or, you could use the name credits for anything lower than 1,000 Digibytes and Digi's for anything above. Sounds correct too, as Digi sounds like a higher number in relation to credits which sound somewhat singular in pronunciation. Credits would be more a known word for small items like groceries, entertainment, cosmetics, clothing etc...while Digis would be reserved for higher priced items like Houses, Cars, Boats, Computers etc..
What are all your thoughts?
