Concerns over a possible security breach at cryptocurrency exchange Binance shook digital asset markets. Bitcoin lost more than 4 percent on Friday, falling to $77,994 and dropping below the psychological threshold of $80,000.
Ether, the second-largest cryptocurrency by market capitalization, fell 4.84 percent to $2,247, while Binance's own token, BNB, dropped 7.68 percent to $694.
Several cryptocurrency companies, led by stablecoin issuers Circle and Tether, froze a total of $2.54 billion in funds linked to the suspected incident. Circle CEO Jeremy Allaire said the company had frozen more than $800 million in USDC, while Tether CEO Paolo Ardoino announced that transactions involving more than $1.5 billion in USDT had been halted. According to Binance co-founder Yi He, Ripple also blocked the transfer of $200 million in funds.

Blockchain analytics firm Arkham Intelligence identified approximately $6 billion in digital assets across 55 wallet addresses that may be linked to the incident. The finding indicates that the scale of the breach could be far greater than the amount frozen.
Binance did not explicitly confirm that an attack had occurred. A company spokesperson said, "Our teams are aware of reports concerning a possible security issue and are actively investigating the matter," adding that user funds were safe. Changpeng Zhao, Binance's founder and former CEO, also said customer funds were safe and described the incident as appearing to be a cyberattack.
The crypto sector has been shaken by major attacks in recent years. In 2025, the Bybit exchange suffered an attack involving approximately $1.5 billion, while rival Bitget recently lost more than $350 million in digital assets in a cyber theft.
