Slouch hat. Vaguely smoking brain feeling: This (so far) does seem to be a legitimate and possibly useful topic of discussion. As "bitcoin" provides a currency with anonymity somewhere between cash and centralised banking systems it has the potential for abuse BUT it is (AFAICS) in no way illegal or wrong in its own right. Just as one would not normally assign moral or legal "values" to "cash", this is (it appears to me) a novel but real means of exchange with value based on the commodities it is used to pay for. I don't expect I will be using it :-) See > http://en.wikipedia.org/wiki/Bitcoin for explanation of system including terms such as "mining".
