Did the March 12 BitMEX Outage Save Crypto? Why Bybit Took Over

The March 12, 2020 BitMEX outage remains one of the most debated moments in crypto trading history, with long-time users still arguing over whether the exchange going dark during the worst of the crash accidentally slowed the sell-off. A first-person retrospective revisits that day and the slower shift that followed, as Bybit gradually displaced BitMEX as the venue active derivatives traders preferred.

The account comes from a self-described long-time BitMEX user in a memoir published on Substack, which frames the March 12 event as both infuriating to live through and historically consequential for the market.

Did the March 12 BitMEX outage actually save crypto?

The outage landed in the middle of the “Black Thursday” crash, when leveraged Bitcoin derivatives were being force-liquidated at speed and BitMEX was the dominant venue for that trading. With so much price discovery concentrated on one platform, its trading engine going offline meant the most active liquidation market briefly stopped functioning.

BitMEX itself attributed the disruption to a hardware and infrastructure problem compounded by attacks, saying its systems were hit by a DDoS attack around that period rather than a simple capacity failure. The exchange later described the sequence of incidents in a follow-up post on how it responded to the attacks.

The “did it save crypto” argument rests on a simple observation: while BitMEX was down, forced selling on its book could not continue. Supporters of that view hold that the pause interrupted a cascade at the moment it was most violent.

The counterargument is that stress does not disappear when one venue goes dark; it moves. Selling pressure that could not be expressed on BitMEX had reason to shift to other books, meaning the outage may have changed where the crash played out rather than preventing further downside.

From the user’s own seat, the memoir presents both feelings at once: the outage was maddening for anyone holding open positions, yet it became the kind of event traders still reference years later. A balanced read is that the outage altered the crash’s dynamics without any clear proof it lowered the ultimate bottom.

Why Bybit took over after the era BitMEX defined

Before its decline, BitMEX helped establish the culture of high-leverage perpetual swaps that came to define crypto derivatives trading, according to the same first-person retrospective. That legacy is why the March 12 episode carried so much weight in the first place.

The handoff to Bybit, as the account tells it, came down to product feel and execution confidence rather than a single dramatic event. Active traders migrated toward the venue where the experience and reliability felt better for the next cycle of leveraged trading.

Reliability and trust matter more in derivatives than almost anywhere else in crypto, a theme that continues today as the industry contends with mounting security and platform-risk concerns. For traders who lived through the outage, confidence in a venue staying online under stress was not an abstraction.

The retrospective frames Bybit’s rise less as a competitor beating BitMEX on marketing and more as a market handoff: the platform that had defined an era ceded leadership to the one traders increasingly chose to route their flow through.

The memoir stops short of a tidy verdict on whether the outage “saved” anything, and so should any honest reading of it. What the account documents clearly is one operator’s outsized influence over a historic crash and the slower loss of that influence in the years after.
