It's pretty amazing that the price is this high. It seems like it must be a short term pump, but you never know.
Nothing lasts that long. Currently the price is being driven by panic buyers that are basically too late, but they still think they can walk out with massive profits. I think for now, the peak will be $1000 or slightly above that, but after that we'll be subject to a correction that will push the price back towards the $800 levels. And to be honest, $800 seems to be a very fair price according to me.
If history is any indication, we are probably seeing a breakout to $5000+...comeback to $1500, rinse and repeat....
The market is already retreating. A 5x increase in price would take Bitcoin's market capitalization to $75+Bn.
Not impossible, but very tough.
