Currently BTC prices have been hovering at 6000, and if the BTC prices fell to $5000, $4000 should be not far off, the market is confirmed in the bear market, want to rise to $20000, you may need a couple of years. 
To tell you the truth?I have been waiting for that to happen since my campaign the Yobit only pays when bitcoin price drops to $5,000 level so the $4,000 is much better for us participants so we can gain our payments
But i know that we had reached the bottom already so what we are waiting now is the pump or recover
