Why would I use Vircurex for trading dollars I hear you ask? Well, you can flog quickly devaluing LTC for a better rate than into BTC right now, hold your dollars, and wait for BTC to correct. Or whatever, do what you want. I don't know what will happen, know that there's some generous offers here right now
