Assuming that OP was simply buying bitcoin (and nothing else...i.e. not automatically selling on an exchange on the backend or something...), then this could be a big shot to Bitcoin.
Unlike other recent headlines (around i.e. Mt. Gox, etc.), it seems like the question here is whether or not bitcoin constitutes "stored value" under VA law[1]. If so, this would render anyone who buys and sells bitcoin a Money Transmitter Business.
That said, I doubt FinCEN would consider Bitcoin "stored value" based on their definition [2] and recent "guidelines".
Stored value laws were created for things like prepaid cards (I believe...[3]), which were cracked down on because of their role in money laundering.
