Kraken down when you just have open short position around the bottom. Reminds me of 6 months ago when a flash crash happened where a lot of people lost everything due to account liquidation.
If this happens again, I'm going to join the law suit as well. You better have disabled all trading and positions. Totally unacceptable.
Any half decent exchange would halt all trading until they are able to provide a decent service. They just say: "Our TOS clearly states that you hold all risk using our service. We never promised anything is actually going to work."
