If bitcoin will go up to $800 then we could see a new all time high in my opinion. We have to cross and destroy the latest 2016 ATH to be ready for the moon take off.
A lot of new money is flowing into btc and this means only one thing, that the way is up.

If Bitcoin goes up to $800 it will probably continue going up to the 2013 ATH, but there might be a retrace off it back down before it goes any higher. Some predict it will surge straight through the 2013 ATH and continue to $2000 or $3000. Others predict it will go up in steps with retraces in between them, and I think that's what will happen.
