Multiple tokens cratered as much as 50% within 30-minutes on crypto exchange Binance on Tuesday, with market watchers wondering if a misconfigured trading bot could have caused the declines.
Act I, the Prophecy (ACT) slumped 50%, DeXe (DEXE) dropped 30% and dForce (DF) fell nearly 20% within minutes after 1100 UTC on Tuesday, data from Binance shows, with no immediate catalyst or explanation behind the sudden fall.
The drop led to $6.28 million worth of longs being liquidated on ACT-tracked futures across exchanges, Coinglass data shows, with a single trader hit with a $3.2 million liquidation.
Around 18:30, multiple altcoins on Binance experienced sharp declines. ACT/USDT dropped over 49% within 30 minutes, DEXE/USDT fell more than 23%, and DF/USDT declined over 16% in the same period. The sudden dips were triggered by large sell orders executed in a short time frame,… pic.twitter.com/tdmPKMfR3l

Meanwhile, HIPPO, BANANA31, TST and LUMIA posted similar declines shortly after 1100 UTC, though not as large as ACT, with dips in some tokens like KAVA getting quickly purchased by fast-fingered traders.
The tokens are not related or in the same sector. Data showed a surge in selling volumes roughly around the same time, with no other tokens on Binance seeing similar spikes in selling volumes.
The stage for volatility was likely set by Binance’s announcement at 10:30 UTC, which introduced changes in leverage requirements and margin tiers for perpetual contracts for several tokens, including ACT/USDT.
The announcement said the new rules will be applicable to existing positions. That likely spurred position adjustments by trading bots, leading to price volatility in perpetuals, which quickly spilled over to spot prices.
The cascade spread over to other exchanges, with these tokens down equivalent amounts on other centralized exchanges as well as on decentralized exchanges.
Early reactions on X ranged from surprise to speculations of a market-making bot possibly causing the declines due to a misconfiguration on how they trade, though CoinDesk could not independently confirm the allegations as of writing time.
“Seems someone has been hacked or banned or idk,” Andrei Grachev, founder at DWF Labs said on X. “Otherwise I cannot explain why too many unrelated assets dumped.”
“Even though the update was on perps, the impact spilled into spot. Traders using cross-margin setups or running arb strategies were likely forced to unwind both sides. Panic from the perp cascade also spread, algos and discretionary players alike started exiting spot just to stay ahead of the move,” pseudonymous observer Game said in an X post.
