These people are keeping BTC low. There are 32k btc sold by people who do not have BTC at all.
For those who don't know the 'short-sale', that is an option that the exchange gives you, to sell something (btc) even tho' you dont have any, and buy later to close the trade.
You sold at 7k, buy later at 6k, you made 1k usd. Trade closed.
If BTC goes up after your short-sale at 7k, you will have to buy at 7.5 or 8k or higher, to close the trade. You lost money here.
