How about e-marks...? Sort of the next big thing after D-marks (Deutche Marks, you know, German currency). I don's like "crydets" because it seems like it's not straightforward pronounciation, especially when dealing with other languages; too easy to confuse with "credits," and "cry-debts" ("boo-hoo-hoo, another collection notice!")... we need a word which is less ambiguous than that. "Cryp" like "scrip" is also like "Crip," which is a very very unpleasant connotation and might leave a bad taste in the mouth of Latinos in the US. E-Marks. Clear and straightforward, easy to pronounce and not too many syllables or weird spelling tweax. -gg.
