Banks are not countries. Banks are not states.
Bolivia did not ban bitcoins. Bolivia's banks did.
Nevada, New Mexico, Arizona, etc. are not warning against using bitcoins. Their banks are.
Saying that a country bans bitcoins when their main banks ban them is like saying that a country has banned Whoppers because McDonalds in that country has banned all Whopper sales in their restaurants.
News alert, banks do not transfer bitcoins. Banks do not hold bitcoins in their accounts. Banning their use in their banks is meaningless.
do you understand that those banks in bolivia are state run? which makes them defacto governments?
They stated that they will only use government currencies in their banks. This does not make all other things illegal in Bolivia.
