In a letter to the US Department of Justice (US DOJ) and the Department of Homeland Security, Warren linked cryptocurrencies to child sexual abuse.

Lawmakers cited a February FinCEN trends analysis of 2020 and 2021 transactions and a Chainalysis report from January, noting that cryptocurrencies have become “the payment method of choice for perpetrators of child sexual abuse and exploitation.” “Existing anti-money laundering regulations and law enforcement methods struggle to effectively detect and prevent these crimes, and we are committed to ensuring that Congress and the Administration do their part to address these challenges.”
