Crypto exchange and derivatives trading platform BitMEX saw bitcoin flash crash below $9,000 on its USDT spot market late Monday but had no impact on derivatives, according to the firm.
BitMEX is currently investigating “unusual activity” involving large sell orders on its 
BTC
-1.50%
-USDT spot market, the exchange posted on X. “This does not affect any of our derivative markets, nor the index price for our popular XBT derivatives contracts,” it added.
“Someone just dumped 400+ BTC over 2 hours in 10-50 BTC clips on the XBTUSDT pair on Bitmex eating 30%+ slippage. They must’ve lost $4m+ at least,” pseudonymous crypto community member “syq” wrote. “I’m guessing that they’re done (for now?). Total volume so far is just shy of 1,000 BTC over 3.5 hours with a low of $8,900. Now BitMEX have disabled withdrawals,” they added.

In response, BitMEX clarified that it had not disabled withdrawals for all users but just a few accounts relevant to its ongoing investigation.
‘Potential misconduct’
BitMEX later noted that it was investigating “potential misconduct” by traders in its BTC-USDT spot market, again re-iterating the incident had no impact on its derivatives markets amid reports of the flash crash.
“This incident had no impact on our billion-dollar derivatives markets. It did not move mark prices, and no liquidations were triggered by it because our indices are independent and battle-tested,” BitMEX wrote.
Explaining the reason for the price drop, BitMEX said, “We create fair and equal markets for all by not employing internal market makers. The BTC sell orders this morning were simply too big and frequent for independent market makers and other traders to react to. As is standard, our compliance team is investigating the accounts and transactions triggering this price movement.”
Deposits and withdrawals continue to be processed as usual on the trading platform, BitMEX added.
Bitcoin is currently trading for $63,112, according to The Block’s price page.
