I still don't understand trading with leverage that well and have or won't do it - still think it's funny that this happened when Mex went offline. No way it is a coincidence right?
Apparently there was a 4k BTC market buy the second bitmex went down, based on my 30 seconds of research on reddit
In this instance, they got liquidated becaue the pricing mechanism for how bitmex calculates contract value (bitmex xbt and futures are derivatives) is based on cash exchanges (50% gdax/bitstamp) so if the price moves up and your margin runs out, you get liquidated. A small % of every liquidation goes towards Bitmex's insurance fund which guarantees that every trade is fully collaterized 1:1 for long/short. The insurance fund stands at 11,5k btc. It's literally gone down only once because some guy found a way to game the system for how bitmex liquidates people.
It was not a coincidence, just a guy who decided he wanted to **** some people in the ass while bitmex was down. Happens all the time.

Looks like all that Tether from last night got out to good use...
Per WSJ:
No one wants to audit them or any crypto based exchange because of the brand and political risks involved with putting their name down on any official document. That's why the Freeh "audit" is what it is, he logged in, saw the balance in the banking accounts and logged out.
