Yes, there are regulations governing cryptocurrency depending on the country, region and/or industry. For example, the United States has the Financial Crimes Enforcement Network, or FinCEN, which is responsible for enforcing anti-money laundering (AML) regulations for cryptocurrencies. Additionally, some countries have issued regulations to govern Initial Coin Offerings (ICOs), a form of fundraising using cryptocurrencies. Regulations may also be imposed by industry self-regulation, such as the Crypto Rating Council, which aims to provide uniform ratings for cryptocurrencies.
