No coin in particular... I was trying to find the biggest losers with -99.9% but unfortunately none exist today. But let's say, I wanted to double my bitcoins with OPENANX since it's the #1, what that be okay? I just focus on the percentages. My logic is, since -99.9% is the lowest it can literally go, it could only go up next time so thus massive profits. I'm more of a long-term trader so, I don't mind holding for months.
