WELL, to answer your question in the most honest way, and considering the fact that you are already down 50%, the simple answer is, without trying to sugarcoat it is : HELL NO! lolz weeeeeeeee ...whenever you let your investment go DOWN 50% or more..its simply stupid. But not as stupid as some others who AVERAGE DOWN and buy more and more until BK pops in or it wipes you out completely.
The most i lose is 2% on any trader. Can't make $ by investing unfortunately. Learn to trade. The rewards i take based on VWAP trend ....but usually when it gets a lift of 5% and higher i will adjust my stop loss at exactly where i bought from and sell only on VWAP indicators, partially as its going up. Repeat the process over and over and that is how you make $, same goes when shorting only reverse what i said. #
