According to the U.S. Treasury Departments Financial Crimes Enforcement Network, as of 2013, using bitcoin to purchase well-natured goods and services is not illegal. However, those who mine bitcoins and trade them for traditional currency or operate exchanges on which bitcoins are bought and sold are labeled money transmitters and could be subject to special laws that govern that type of activity. To date, those laws have rarely, if ever, been enforced to crackdown against bitcoin use.
