There is a massive problem with people panic selling usually because they bought way more than they could afford and trying to claw back any losses. They will more than likely be the ones sorry when value is returned to all time highs.
If you bought the top, there can be a logical reason to sell at these levels. If your TA/FA analysis suggests that price is to fall further, you sell your position to buy back in lower. this obviosuly doesnt make sense if you bought below 5k as you lose your position.
