Is there any regulation governing cryptocurrency?

Yes, there are regulations governing cryptocurrency in many countries, although these vary from country to country. In the United States, for example, the Securities and Exchange Commission (SEC) has published guidance on initial coin offerings and cryptocurrency investments, while the Internal Revenue Service (IRS) requires that transactions involving cryptocurrency be reported in the same way as transactions involving other assets. Other countries have taken a more restrictive approach, banning cryptocurrencies altogether or introducing stringent laws to regulate them.
