Binance Research reports that illicit cryptocurrency transactions account for less than 1% of total on-chain transaction volume. As of 2025, over $75 billion in illicit funds remain on-chain, marking a 28% increase from 2024. Despite this, the capacity of major mixers is limited, with laundering $1 billion potentially taking over 100 days. The report also highlights that more than 80% of these illicit funds have been transferred to downstream addresses. However, blockchain technology continues to enable the tracing of these fund flows, maintaining transparency in tracking illicit activities.
