According to new research from Binance Research, the total volume of illicit crypto funds remaining on-chain has exceeded $75 billion in 2025, marking a 28% increase from 2024 levels. The figure, shared via the firm's official X account, represents the highest annual total since tracking began in 2016. Despite the headline number, illicit transactions account for less than 1% of total on-chain transaction volume, reinforcing that the vast majority of blockchain activity is legitimate.
The report highlights multiple factors driving the rise, including larger individual heists and increasingly sophisticated laundering attempts rather than a broad expansion of criminal activity. However, the infrastructure designed to thwart cash-outs is maturing rapidly. Know Your Transaction (KYT) systems flag suspicious wallets during monitoring, often before funds reach exchanges. Know Your Customer (KYC) procedures then block withdrawal attempts when flagged wallets appear. Additionally, stablecoin issuers like Tether and Circle can freeze funds linked to sanctioned or suspicious addresses, while law enforcement agencies conduct direct seizures from wallets and exchanges.
A critical bottleneck for launderers lies in the limited capacity of cryptocurrency mixers. Binance Research estimates that the largest mixers process roughly $10 million per day, meaning laundering $1 billion would take more than 100 days. While over 80% of illicit funds have been moved from their original wallet addresses, every transaction remains permanently recorded on the blockchain. This transparency means tracking is never truly broken—only delayed. The findings underscore a growing narrative: blockchain’s public ledger is a powerful deterrent rather than a tool for anonymity, as compliance measures and law enforcement coordination continue to improve.
