There are lots of speculations about the potential price of BTC after the decrease in the last few days. In my opinion Bitcoin is still bullish and it's waiting for a big rally to come. I think for now Bitcoin is still testing the 600/590 level. (If it breaks we will go down to around 560 USD.)
My opinion is that the reactance is to strong to go down any lower for a week or more. After a few weeks we will be back around 600. Than the price wil go slowly upwards and if the price reaches 680 USD, Bitcoin it will go up to start a new big rally.
