On Bistamp is just above 2500$,but on Bitfinex&Poloniex is around 2460$,all exchanges are in red now.It is hard to say what is reason for this declining of price,only thing which is certain when it comes to BTC that at some point we can expect a correction in price.These days that difference can be pretty big,like this one and that one week or two ago when we see 1000$ price drop i just few days.
I would say that always someone take profit,whales never sleep
