@SoF, that's not even remotely relevant to the discussion, then, since it has nothing to do with branding, but with differing state regulations on gasoline where some refiners and manufacturers are more inclined to cater to certain markets with particular regulations.
Think you are correct I meant in terms of a liquid exchange the fungibility of gasoline should not matter rather bureaucratic regulations can make the same product become slightly different to address superficial concerns, perhaps that was a bad example in that case I mean the difference between shell gasoline husky gasoline Amoco gasoline Texaco when you go to a gas station.
What I was trying to illustrate was that bitcoin could be branded differently if different companies advertised different things about them, or do you not see any brand value attached towards it. I read label as brand.
That said I think I misread your response
I read your post as a marketing question not as people will buy BTC over XBT if your point was the name is different but they are the same thing then I agree with you, if the question was if different firms were selling escrowing or holding bitcoin and individuals had a choice then I think some premiums may be given to certain firms and organizations over others.
This is observable with the difference in rates among different exchanges although probably to a fairly insignificant level as other factors such as liquidity fees and ease of transferring assets come into play.
The most valuable factor of course being the Security aka the X as we saw with Mtgox the bitcoins are only as valuable as the amount remaining.
In other words I think branding is important in this case, if not naming.
Personally XBT or BTC I prefer BTC since it's the more familiar name and the one that's been in use for years.
