Seems to have been a short-term phenominon, probably fueled by that BTCC taking payments directly announcement.
Price has slid quite a bit already since the peak, and seems to have settled into a steady drop mode (I'm guessing it won't go all the way back down to $230 but I wouldn't bet against $250 by year end).
If you already have gear, this was a very nice "help achieve RoI and even some actual profit" situation - but it's not looking like anything more than a short-term bump and NOT enough to make it likely you will achieve RoI on anything currently available if you buy now and you DON'T have very cheap electric.
