Most countries dont see bitcoin as a competitor or a threat but take some security measures regarding how secure could be; for example, United States consider bitcoin not a coin but a commodity according to the IRS but in a report in recent years showed that only a small amount of people declare they have bitcoins and they treated as criminals.
The problem with these countries is that most of them have a monetary policy that guide them and theyre the only authority established by the State to create money.; thats why the United States in a Congress Report suggested to consider them as a commodity (due the price fluctuation) and not a currency.
Lots of people are using bitcoin in order to find some financial help to save their assets. For example, in Venezuela bitcoins demand is big because their currency is dead, its useless to save something with the Venezuelan bolivar and too difficult to find dollars (USD) so they use bitcoin in order to save the money and hope to gain some value. Its affecting in a small scale to the economy and the State is prosecuting those who use bitcoin. No joke. They detained two engineers for mining.
Take a read at the document, there is much more information in there than just the usual Gov is bad, cryptos are this and that... They are clearly recognising the value of the technology and that means real money will be injected.
