if they THEMSELVES cause panics and selloffs, don't they massively profit on exchanges when the price bounces back up?
what can be done to counter something like this? simply have more exchanges?
As you can already see in some of the threads, an exchange has no incentive to do this, because trust in the exchange would be damaged beyond repair. No trust in an exchange means no trading there - so no fees, and they are done. I'm not sure what happened other than large size - but I'd like to know where that came from.
Perhaps the exchange owners will post, who knows...
