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.
You know even last year, bitcoin doesn't have any legality in many countries, but prices can go up thousands of percent to $ 19k, so the requirements to recover or pump are not just legality, there are many other aspects that affect price changes such as speculation, news, adoption, etc
