It's so easy in hindsight, and foresight is difficult when you're blinded by the crazy gains. Even in Gox's dying moments, people were shorting like crazy, trading Gox coins for Good coins etc, hedging on the hope that one day they may get them back.
I remember that phase well. The idea of profit was blinding people to the obvious outcome. One poster here wired in $55,000 a few days before it completely went up in smoke. There's managed risk and then there's just deranged vulturedom.
You'd have to be pretty heavily blinkered to not be aware of what was going down. That's not a hindsight thing. I wasn't interested in touching Gox when it was still number one.
