Illicit crypto on public blockchains has reached about $75 billion, but that still accounts for less than 1% of all on‑chain transaction volume. The estimate fits what analytics firms have said for years: crypto crime is big in dollars but small compared with the overall market.
According to Binance Research, more than $75 billion in illicit funds sat on‑chain as of 2025, up roughly 28% from 2024. This covers funds tied to scams, hacks, darknet markets, sanctions evasion, and similar criminal activity that analytics firms have flagged. Chainalysis, for instance, says wallets linked to illicit activity received about $154 billion in 2025, when sanctioned entities are included, the highest level yet.
Even so, Binance’s numbers and other reports say this is still a small slice of total crypto use. Chainalysis found that illicit transactions accounted for less than 1% of overall crypto volume, while TRM Labs put the share at about 1.2% in 2025, down from 1.3% in 2024. Researchers caution that these are lower‑bound estimates, since they only include known addresses, but the share has continued to shrink as legitimate activity grows.
Why “only 1%” Still Matters
Binance Research says $75 billion in illicit crypto remains a serious problem, even if it accounts for only a small share of total on‑chain flows. It notes that mixers and other hiding tools have limited daily capacity, so fully laundering $1 billion in stolen funds through major mixers alone could take more than 100 days. That bottleneck, combined with blockchain’s permanent record, gives law enforcement more time to trace and freeze assets and makes it harder for criminals to cash out in fiat without being detected.
Other investigations put things in context by contrasting crypto to traditional finance and indicate that the unlawful volume on key exchanges is in the low billions, well below the trillions that global watchdogs estimate for traditional money laundering every year. But authorities and skeptics say research firms can still miss some transfers, especially when criminals use long chains of intermediaries or loosely regulated platforms.
A key shift is where illicit activity now occurs on‑chain. Chainalysis reports that stablecoins account for roughly 84% of illicit transaction volumes, while Bitcoin’s share has dropped to around 7%. This change reflects the broader rise of stablecoins in both normal trading and in scams, sanctions evasion, and high‑risk offshore activity.
