With momentum really starting to build behind using 'bits' as the primary unit for Bitcoin (as pointed out elsewhere, two decimals fits much better into legacy finance systems) I've been pondering symbols.
I was trying to tie in greek letter mu (µ) as the SI unit for a millionth, but nothing seemed to work.
Above all else, I wanted it to have an explicit relationship to the dominant Bitcoin symbol (and pursue the optimal route, of coming up with something unique rather than just cludge-repurposing some existing unicode char.
Please comment, remix, argue, encourage, discourage, as you feel appropriate below.
1. "b" - for bit
2. Related with bitcoin ("B" and "b")
3. Related in right way ("B" for bigger unit and "b" for smaller one).
What's not so good is the graphical view of the symbol:
1. There is no standard ASCII symbol for it.
2. The vertical bars have different width. IMO, if they were the same width it would be more laconic, more harmonic and easier to draw.
