I think most gov'ts have an issue with individuals or corporations issuing their own money, and I'm sure my country has laws against it which is why they're attacking Libra.  This isn't anything new, either.  There have been laws on the books for many years now.  States in the U.S. used to mint their own currency until the federal gov't put a stop to it and passed laws making it illegal.

Don't know about other countries in S. America but Venezuela at least needs an alternative to the bolivar right now.  Foreign currency might do the trick in the short term, but this is a great opportunity for long term crypto adoption if only businesses would accept it as payment.  That's out of our control unfortunately.

Nevertheless, believe me they're hostile towards it.  All gov'ts are even if they've not yet passed laws restricting cryptocurrency.
