The price recovered quickly, I believe this will be above $ 620 at the end of the year.
I think the bitcoin price will rise faster than that. The $620 could be reach this or next month. End of year price could be $850.
It's hard to say if the price will get back to 620 or to 850 for that matter. At this moment we know that the halving is over + the price is affected by the recent hack of bitfinex.
So at this moment we can expect nothing, unless offcourse there is some good news. Which I am expecting for quite some time now, The currency market is broken and bitcoin should fill the gap where traditional currencies are leaving those gaps.
