The whole unit change seems so disruptive and difficult to coordinate now -- do we really want to have to deal with another one later when there are way more people to try to coordinate? I really think we should look to the endgame and figure out where we want to be.
I'd propose moving to uB (micro-bitcoin = 1e-6) as the standard unit now and forever. For now, it can be referred to as uB or uBTC, but over time, once it's ubiquitous, it should just be called a bitcoin. Because the smallest unit is the satoshi (1e-8), this means uB-denominated prices would get 2 decimal places maximum, which is the most that any consumer wants to deal with anyway.
I'm against using micro-bitcoin now so we can switch to bitcoin later (when? - not a good idea: confusing!).
The idea about defining the standard as 1e-6 isn't that bad. I think the two decimals for regular consumers might be a good idea.
BTW that could also be called hSatoshi (hecto Satoshi) according to SI-standards.
At the same time, I'd propose inverting the exchange rate, so instead of quoting uB/USD = .00013, it would be quoted as USD/uB = 7692. This is exactly the same way Yen are quoted relative to USD (USDJPY = 100.66), and is also the same way other private virtual currencies such as WoW gold are quoted.
And again our beloved American(s) are unaware that they are not alone on the planet and that their customs are not
necessarily the global standard!
Every "big" economy uses their currency as the base currency and all others as counter currencies.
It might be standard in the US to quote the Euro as USDEUR or USD/EUR
but in Europe all currencies are counter currencies to the EUR => EURUSD, EURGBP, EURCHF, etc.
I assume that China and Japan act the same way.
Since BTC is a global, nation-less currency (and the biggest of all crypto-currencies for that matter) the only logical step is to quote
BTCXXX (including BTCUSD). What is more, the base currency is usually regarded as dominant / of more value.
