that is right. bitcoin does not needs aproval because it is only built online without anyone controlling it. though some countries are strict when it come to new technology that they are not really familliar with. the government of a certain country can still set a rule or a law because they do still control their country. other reason is that they are anti bitcoin because they cant totally put a tax or any other charges thru it. they are arfaid because if more people can recognized bitcoin , sooner or later all people will now use it and the fiat will be totally forgotten . which means they cannot earn an incentives no more.
