nothing will happen at the halving, at this point i'm expecting something major later this year or even early 2017
I feel the same and unless there is some big controversy like last year we had the auction, we could expect nothing positive this year as well. 2016 is half over and may be by December, we can expect a rise and fall.
We can't say it blankly. At least a small impact will occur over bitcoin price on halving. After this if the technology permits we could see a gradual increase that might reach a higher value when it reaches near to December.
