Who cares if bitcoin is declared legal or not in your country? I'm not using bitcoins because my government said it's OK I'm using it because I can make my own decisions with my own money.
More likely, who cares if bitcoin is declared or not in each of everyones country, we can use it as long as we are not violating any rules of the law and we are not harming any one.
Actually, having and using this doesn't give any criminal liabilities to us that make us afraid to have it in our wallet. Declaration of bitcoin legalization is totally a long way process, it takes time to have a final decision from the authorities. Once it become legalized, probably it is possible taxes will be imposed to the bitcoin holders. But in terms of controlling bitcoin-absolutely they can't make it.
