There hasn't been a country who said that bitcoin is totally "illegal" those who made some regulations are China, Usa and probably the India, but they didnt said that bitcoin is ilegal, a regulation is something completely different. Just remember that China is not killing anyone just because using bitcoins, they are only shutting down some exchanges in their countries, but nothing more.
Bitcoin is legal in most countries all around the world.
Everyone is hoping that bitcoin will legalize all over the world because if it will happen for sure it has a transparent for all. We love to do transction and for that we wanted to be open for all for the sake of everybody. If this will happen probably theie is tax which implies an amount for the country although it is helpful for all.
