BOLIVIA
the central bank of bolivia,el banco central de bolivia said in a statement:
"it is illegal to use any currency that is not issued and controlled by a goverment or an authorized entity."
Well this is the government decision nothing can do with that lets respect the government decision and besides the government has a true power to ban bitcoin in every country, I think the government don't know how to put regulation on bitcoin and its hard to identify who are the users of it so its hard to implement to put tax on it and the there are many scammers who used bitcoin for their scheme so I think that is the right decision for their country.
