Bitcoin price will again go down to 600-650$ by june-july end.By august it will be definitely in range of 600-650$
Bitcoin value will again start dropping down after reaching 1.2k$ or max 1.3k$ or else will start taking fall soon.
As per reports in a month or two bitcoin will again start falling down from 1000 slowly and steadily and will reach 600 in 6 months and will again start rising after september end/october.
I suppose that this speculation has just only made by you, well I agree that bitcoin price will drop as we can see in the previous months but I don't think that the price will eventually fall back in to the $600 value in some remaining months of this year . As long as we are still on the good price and there haven't been any huge fall i won't believe that it will occur .
