Legislation to protect UK consumers from misleading cryptoasset promotions is set to come into force later this year.
The new legal rules will also apply to companies based overseas, according to a tweet from HM Treasury.
A draft of the Financial Services and Markets Act amendment, published this week, will enable the Financial Conduct Authority to regulate crypto firms under existing promotions law.
Companies that are registered with the FCA will be able to approve their own ads for a limited period of time.
The Financial Services and Markets Act is set to be debated in Parliament.
