I don't hate it. It is the most obvious choice and popular consensus seems to have dictated that something resembling a 'B' with currency slashes be the symbol.
Are we discussing an abstract symbol (glyph) or logo? If it is decided (against my lone protests) the abstract symbol is a B with two slashes, then I think your logo is lovely. It has clean lines, no cramping, I agree you accomplished your goals. But are you also suggesting a modification to the abstraction? That other logos imply three vertical lines whereas you propose only two (something like a 3 with || rather than a B with ||). These seems a question of penmanship or font rather than glyph. Am I mistaken (I'm willing to bow to your typographic superiority on this one)?
I don't think it needs to emphasized any more than it is already apparent. It acts as a good story as to why character looks the way it does and what idea it grew from. A lot of people don't notice the arrow in the Fedex logo as obvious as it is. My vertical lines are set at a diagonal like most # signs but I'm not against them being styled as true verticals as some typefaces might dictate that they need to be.
I am not much concerned with the logo. I appreciate the need for a logo and am happy to see consensus come up with one without me. If B with slashes is final, then your logo is as fine as any I've seen. But in common writing we will use ASCII. I don't expect a Unicode addition in this decade, nor do I think using an arcane greek, diacritic, or any other clever appropriation from the basic multilingual plane will help bitcoin's adoption. When it becomes as common as gold, I hope the glyph question will have already been answered by a billion humans. In the meantime, I think it will be more important to handle SI prefixes: millebtc, microbtc, nanobtc, and hopefully picobtc. I don't expect pico฿ gaining much traction, ever.
