Just had a call with a well-connected market-maker operator and board member of a couple of exchanges. He walked me, step by step, through EXACTLY how this crash unfolded. 👇🏻
That wasn’t a “normal dip.” It was a one-minute crash where alts dumped 60–90% and instantly bounced before most people even opened their charts.
To make sense of it, you have to start with: A-book vs B-book. In B-book, the venue/internalizer literally takes the other side of customer trades. If you lose, they win. Those orders never touch the “real” market. (Sadly, almost every CEX does this.) In A-book, the venue routes your order out to external liquidity. If you win, they are protected. Most retail perps flow sits comfortably in B-book, until the risk gets too one-sided. When the crowd piles onto the same side (think high-conviction longs), the venue’s B-book P&L becomes dangerous. That’s when they flip some streams to A-book or, if needed, force a reset: thin the order books, pull bids, accelerate the move, liquidate crowded leverage, and reset risk.
Here’s where the Binance gravity well matters. Like it or not, a huge number of smaller exchanges route their A-book flow into Binance (fee-share B2B, lowest latency, deepest order book). If the big market makers pull quotes and the books go thin, even small sells can fall straight through the floor, cascading liquidations follow, then fast re-quotes appear once MM risk is clear. That’s why this event didn’t look like 2020. Back in the COVID crash you had a multi-week base after the dump: time to react in spot. This time it was a 5–10 minute slap on your face. Latency/credit won and retail lost, as always. The speed of that rebound says a lot, it felt more like a market cleaning than any real macro collapse.
Retail aped too hard on perps and got cooked. CEXs used the chaos to reset B-book risk and refill insurance funds by forcing liquidations (ADL). DEXs look cleaner after this mess, and rumors say some CEXs were longing with client funds. If that’s true… we might see a few blowups soon 👀
But why now? Incentives. Q4 is “up-only marketing season,” and tax timing helps too: plenty of pros would rather realize gains next tax year (sell in Jan) than in Nov/Dec and if you’re still reading this you might be retarded.
