Could you tell me the reasons why you believe that the market can recover after reducing to 4000$. I dont know why. Because it depends so much on the acceptance of big countries in the world such as America, China, Japan, EU,... If they still keep the bad view for crypto currency, I dont believe the market can recover.
This is relatively simple, the market is going to recover because the technology is not static, the technology is still improving and when bitcoin finally activates the lightning network then people are going to go crazy over it because that would mean that we will be able to use bitcoin as a currency once again.
