No wonder if in some countries, you meet Bitcoin ATM machine. it is a form of Bitcoin service to its customers to make it easier for people to get Bitcoin. for countries that have adapted and certified bitcoin such machines are not strange. Nothing is possible I think there are many people who have an engagement to this system who are very happy to know that there is such a machine. I believe it's legal and legal because the bitcoin system is legal to your country and of course it has permission coming from the government in your country.
