Yeah, and those people made out like a bandit when they rebought at $6 and $100, and if we're ever at $xxxx (I say "if," not "when," because I don't know about you, but I'm not a psychic), the same people bragging about buying at ATH will come out of the woodworks, start shouting the same thing about 100k coins, and then holders should be worried again.
The point is that most traders lose money. The forum is littered with people who sold early and wished they hadn't. There may be a very select few who have sold at near a peak and bought in much lower. It isn't the vast majority of the bearish posters on here who simply wish to buy at a low price. I would say buying at a third of the previous ATH is a decent entry.
