John McAfee said that it is not the responsibility of cryptocurrency firms to help prevent crypto use in crime. McAfee delivered his remarks in an interview with Washington D.C.-based news agency The Hill on Nov. 11.McAfee argued that authorities should not require cryptocurrency companies and trading platforms to help them control digital currency use in illicit activities.

Despite McAfee's assertions that cryptocurrency firms are not responsible for tracking suspicious behavior associated with digital currencies, other industry players are taking a more active role. Recently, blockchain analytics firm Chainalysis launched alerts for suspicious transactions across 15 major cryptocurrencies. The tool is meant to help cryptocurrency exchanges and other financial institutions mitigate their regulatory and reputational risks.

According to a Chainalysis report released this spring, 64% of ransomware attack cash-out strategies involved the laundering of funds via cryptocurrency exchanges, 12% involved mixing services and 6% involved peer-to-peer networks, while others used merchant services providers or dark web marketplaces. In late August, Chainalysis revealed that stolen funds represented only 8.1% of all funds sent to cryptocurrency mixers.
