I can't access the document, is it still online?

Personally, I think the unit "Bitcent" is underrated. It's true that it is equivalent to a quite high value of currently around $300 USD. But it is still a number not too far from many everyday purchases (rent, clothing, weekly buys in the grocery, up to small cars all are things between 0.1 and 100 Bitcents). And the term "cent" is established in many currencies, people will immediately know what's meant (1/100 of the main unit). It could be used this way up to the 100-200K, maybe also 300-500K (then the smaller items would be priced 0.01 to 0.1, but this is still a manageable number) price range for BTC/USD. And for everything below we can use satoshis.
