If you still have the idea of selling or buying bitcoin in 07/09/2017, then I recommend patience. As a matter of fact, bitcoin price is still growing, so why not be patient even more? If you are in need of money or have financial problems, then you should sell your bitcoin. Don't live a life without money when you already know that money is within your hands.
I will suggest the same to bitcoin holders. We all know that there are maximum chances of bitcoins touching 5k dollars and even going beyond in November, so why to waste bitcoins right now when little patience can make you richer. I would cash out some of my bitcoins in December to enjoy the sweetest fruit ever of my patience.
