Mnuchin said that the Treasury was increasingly concerned about cryptographic money laundering and Libra

• US focuses on "growing concern" over misuse of crypto
• Seriously worries about misuse of Facebook's Balance
• Treasury has very clearly explained to Facebook and Bitcoin users that they should implement the same anti-money laundering protections as traditional financial service providers.
• Bitcoin is a national security problem
• Our problem number 1 is that we do not want bad actors using cryptocurrency
• On Libra: "I'm not comfortable today"
• "I do not know why Bitcoin is negotiating where it does"

Looks like Mnuchin is not a big crypto fan. There was some fear that he would knock the hammer down, but that sounds more like a warning.

Bitcoin fell from $ 10,500 to $ 10,300 after the announcement of the press conference.
