During [2017 to 2021], Binance processed transactions totalling at least $2.35 billion stemming from hacks, investment frauds and illegal drug sales, Reuters calculated from an examination of court records, statements by law enforcement and blockchain data, compiled for the news agency by two blockchain analysis firms. Two industry experts reviewed the calculation and agreed with the estimate.
Separately, crypto researcher Chainalysis, hired by U.S. government agencies to track illegal flows, concluded in a 2020 report that Binance received criminal funds totalling $770 million in 2019 alone, more than any other crypto exchange.
