[Tex/LaTex] Bitcoin symbol in LaTeX

Question

How do I write the Bitcoin symbol in LaTeX?

• Abusing Unicode, "B⃦" can be used in normal text files. I'm not a fan of writing non-ASCII in LaTeX, as you can run into all sorts of encoding issues.
• There does not seem to be a package defining it.
• I could use TikZ to roll my own version, but then that would probably not scale well (telling from past attempts at similar things).

So: what do you think would be the best way of writing the Bitcoin currency symbol in LaTeX?

For comparison, here's the Bitcoin wiki entry for the symbol.

Answer 1

Three examples, from here:

\def\bitcoinA{%
  \leavevmode
  \vtop{\offinterlineskip %\bfseries
    \setbox0=\hbox{B}%
    \setbox2=\hbox to\wd0{\hfil\hskip-.03em
    \vrule height .3ex width .15ex\hskip .08em
    \vrule height .3ex width .15ex\hfil}
    \vbox{\copy2\box0}\box2}}

and

\def\bitcoinB{\leavevmode
  {\setbox0=\hbox{\textsf{B}}%
    \dimen0\ht0 \advance\dimen0 0.2ex
    \ooalign{\hfil \box0\hfil\cr
      \hfil\vrule height \dimen0 depth.2ex\hfil\cr
    }%
  }%
}

and

\def\bitcoinC{\leavevmode\rlap{\hskip.5pt-}B}
