Bitcoin price goes up, many people are in a panic sell your coins.
just look at the overall market http://coinmarketcap.com/currencies/views/filter-non-mineable/

But simple calculations show that the price of Bitcoin will hardly be able to stay at the level of $ 1,000.
for example every hour produces 75 Bitcoins.
Ie in the one day, mining in 1800 coins.
Now Multiply this price by $ 1,000.
Received on maintenance of the course at around $ 1,000 will need a daily inflow of 1.8 million $, for  buy these coins.
This is a rather high figure.
So I think that this panic selling coins at a given time is a 100% loss.
