Which of the following do you prefer?
A slight update of Bitcoin’s original B symbol – keeping two lines above & below the B; no serifs; B is vertically straight, not tilted.
A more modernized update of Bitcoin’s original B symbol – a single line above & below the B; clean lines; no serifs.
A completely new B symbol – based upon suggestion of bitcoinsymbol.org . Uses a variation of Unicode character U+0243 (in different typeface) – so can already be used by any Unicode text editor.
Uses the Unicode character B symbol from Logo C – but italicises all lettering to communicate forward movement.
