TLDR: Telegram paid $18.5 million and returned the proceeds of its coin offering back to investors as part of a settlement with the U.S. Securities and Exchange Commission. The agency sued the firm last year for raising $1.7 billion through an initial coin offering to fund the development of its blockchain project, known as the Telegram Open Network. The settlement comes as U.S. cryptocurrency firms continue to seek regulatory certainty for the industry, including clear guidelines for digital coin offerings.
