Gloating is kind of uncool, mkay.
Seriously though. Those who feel the need to rub it in, don't come complaining during the next flash crash (hint: they always come at some point) when the equivalent kind of ridicule is targeted at you while you stare at the screen in disbelief while watching the USD value of your account taking a big hit.
This isn't gloating. It's ridiculing someone for their extreme whining and entitlement mentality. "Bitcoin didn't make me rich in six months. So you all suck and the world is against me! /emo"
Most of us have lost money at one time or another, but we don't go rattling off like a butt-hurt twelve year old about it.
