It reminds me quite a bit of mp3 files in 1997, when they were just a novelty and record companies didn't know what to make of them. Despite those industries' efforts and help from various world governments, MP3 filesharing, still exists. Likewise, it seems possible that BitCoin exchanges will still happen despite it being illegal. Is there a way to even shutdown BitCoin or would it turn into a pseudo-arms race like filesharing has become?
