Even 'ubit' would be a million times better.
How many marketing firms do you think would tell you that "ubit" is a better brand than "bit" for a unit of currency?
In order to gain adoption, a "startup currency" relies in large part on its brand. see: every shitcoin. If bitcoin had been called humbuggers or some random shitty name, nobody would use it. And since we clearly will be using units much smaller than 1 bitcoin for every day purchases, that smaller unit needs a good brand.
