This isn't going to happen. There won't be an ATH run up until after the halving, if ever. Sorry moon kids. 
Come one man!
Nobody knows what will happen.
Therefore your negativity makes no sense.
Or are doing this on purpose because you hope the opposite will happen?
You know like some kind of superstition.
You're right, nobody knows for sure, but my opinion is that we won't be seeing a new ATH until after the halving, if ever.
I have been following Bitcoin since late 2011 and was a miner through the first halving, and that's the experience I have in forming my opinion. I'd like to be wrong, but I'd bet a BTC or two that I'm not.
