Just hold, don't scare 
when bitcoin price are falling we should hold our bitcoin and also we should not scared on holding because when bitcoin price dump there is a possibility that will increase soon so that if bitcoin price falling we should hold until bitcoin price gets high or increase the possible attitude that we have on this kind of situation is we should have patience. There is nothing to do specifically during a market fall. Only thing that should be done is waiting patiently if you have loss.
The market will turn back with a stronger mode, recovering your loss.
