Buy and hold, or risk selling at the bottom and losing your position. After this dip stabilizes, we are going $2000.
This is true and i think the one who get panic on dumps gonna loss big and will blame bitcoin volatility for their loss 
Dumps are actually opportunity to buy cheap bitcoins
I guess the traders who got panic in recent fall down will start booking profits when bitcoin again tests $1000 or $1100 levels. But, with that rally bitcoin may reach $!500 or $2000 also. This way, selling at bottom may happen in rally too.
