Yes ofcourse it can rise up to $800 this year. My predictions may be a little low compared to other, but I would be pretty satisfied with a rise up to $800-1200 this year.
I am sure this will happen around halving, and not months after halving. Why? Simply because it's around halving everyone want to jump on the train. No one awnts to jump on the train when it have passed many stations.
Lets just hope we see the moon for bitcoin price soon.
I don't think $800 can be achieved in this year, as price rise is slow, its taking too long even to reach $500 so I think we need to wait long to see that price.
Why do you think it will take more than this year to reach that amount? You know that the miners must be profitable right? And they wont be profitable when their production fall in half. So in order to be profitable, they must manipulate the market, and yes, when big miners or investors go hand in hand, they can easily manipulate the market. Just look at the chineese exchange..
I think we must wait until halving reach so we can predict graph trend for bitcoin value whenever it will be raise or not.
About $ 800 , I think it's quite high value so it's impossible to reach on this year but going higher than current value !
