What government regulations apply to cryptocurrency?

The answer to this question varies depending on the country in which the cryptocurrency is being used, as regulations vary from country to country. Generally speaking, most countries have some form of regulation on cryptocurrency, including restrictions on who can own and trade it, taxes, and anti-money laundering measures. Some countries, such as Japan and Switzerland, have imposed very stringent regulations on cryptocurrency use. Other countries, such as the United States, have yet to implement any comprehensive regulation on cryptocurrency.
