The bitcoin price almost doubled in the last 12 months. So it will need some more time to correct the price.
I think the bitcoin price will trade around the 650 dollars level for some time, then it will jump to $900 to 1000.
To see the price of $900 I think we need to wait for a long time as its not easy to reach there very easily as we are still below $700 level so it will definitely take some time to achieve it.
I don't see it happening such a large increase to 800 or even 900 dollar will happen.
