Bitcoin Halving : 3 Hours And Counting

Just 3 hours from now the Bitcoin Halving is started to happen. Everyone is watching the time eagerly.

The Bitcoin Price Index (BPI) were playing at USD650 mark only. Maybe because everyone has taken a step to stay out of the market.

What will happen next is anyone guess. No one is absolutely sure.

Can Bitcoin Goes To USD$ 1000?

What is the better pricing for Bitcoin? Which exchange rate is more suitable?  Can it goes below than USD$ 400?

Who can correctly guess it prior to second Bitcoin Halving?

Any ideas?
