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.
Government should give breathing space to facebook and also other blockchain start up, the only aspect i feel government is needed is regulatory area to protect all players.
