The regulations for cryptocurrencies vary depending on the country. In the United States, for example, the Securities and Exchange Commission (SEC) requires that certain cryptocurrencies be treated as securities and registered with the SEC. Other countries have different regulations in place, including requiring certain types of tokens and coins to be registered or licensed with their respective financial regulators. Additionally, most countries require certain know-your-customer (KYC) and anti-money laundering (AML) provisions in order to prevent criminals from using cryptocurrencies for illicit activities.
