In a blog post on March 23, BitMEX addressed what it says were “a number of questions” from traders since the event occurred eleven days ago.
BitMEX: insurance fund functioned as normal
At the time, BitMEX appeared to suffer from what various sources have called a cascading margin call, forcing out traders and sustaining the price of Bitcoin plummeting in the process. The exchange then went offline for around half an hour, after which the price recovered.
Explaining its role, the blog post states that the fund’s primary purpose has always remained the same: to prevent auto-deleveraging (ADL) of successful traders’ positions to prevent the bankruptcy of positions that get liquidated.
“It is important for the Fund to be large enough to absorb intraday shocks, to avoid ADL on the platform,” it summarizes.
Fund’s size raises questions
Not everyone was convinced. Responding to the post, Twitter-based trader lowstrife argued that questions remained about BitMEX’s modus operandi.
“The main question I raise here is why the insurance fund, when the worst-case scenario almost happened, was barely used,” he commented.
“Which raises questions of why it's so large, and it's overall efficacy. Here we arrive at the limits of my knowledge and opinion.”
