US is slowly becoming crypto unfriendly country with its stricter rules and regulations.
It may be true because he indicated later that he wanted this technology to go ahead.
I also don't think the US government will be the only one. The FATF expects member states to implement these standards by June.
I want to add this quote:
“We will not allow digital asset service providers to operate in the shadows and will not tolerate the use of cryptocurrencies in support of illicit activities,”
It seems that the focus will be on exchanges which may be through platforms, individuals, entities and everyone who provides crypto services, and perhaps it will extend to platforms that operate in the exchange of cryptocurrencies "that are not related to cash.
FinCEN will hold any entity that transacts in Bitcoin, Libra, or any other cryptocurrency to its highest standards.”
