Ok, now I understand the problem. People were not able to close their losing positions because of illiquidity, where a stop loss could not be executed. So basically they were exposed to unlimited loss. This kind of sh*t can happen to any currency and none of us are safe no matter how we protect ourselves.
I think countries with central banks doing this kind of stuff should be invaded by the rest of the world
Stop your whining, you're the "other side" as you said before so you have nothing to worry about. These sorts of moves are good, just like the flash crash as they show you the ultimate risk out there, currencies were attracting too many people that shouldn't be near trading anyway.
