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.
Exactly! I think this is you who has to decide when to sell it or you need to buy it. But the trend which is mostly followed by most of the traders and investors is that they buy the Bitcoins when they see prices are going down and mostly dont sell them even if process are keep on increasing high, instead they keep it.
