The US Senate banking committee wrote a letter to facebook questioning about the nature and legality of it's cryptocurrency project code named Libra.
https://www.banking.senate.gov/imo/media/doc/5.9.19%20Facebook%20Letter.pdfThey essentially asked whether it would enable users to have privacy and would make it harder for the government to monitor every personal and financial moves of people in the US and around the world.
Hahaha, some people are now getting scared, I have a very good feeling that in few years to come, the government will seize to exist, because the only way the government can control the people is to control the finance, and once we get to a level where everyone could control their own finances without the need of the government, then the government will become obsolete, this is why they are so scared and will do anything possible to avoid mass adoption of crypto, but I don't think Crypto is something any government of the world could fight even if they come together as one.
