During a commencement speech at Ohio State University, Christopher Pan admitted to using the psychedelic drug ayahuasca while writing his speech, sparking controversy.

Pan faced backlash for promoting cryptocurrency, specifically bitcoin, which resulted in boos from the audience.

The speech included a demonstration with OSU President Ted Carter and a giveaway of custom message bracelets, despite the criticisms.

President Carter's involvement with TeraWulf, a Bitcoin mining company, as chair of its audit committee, raised questions about university presidents participating in cryptocurrency businesses.

TeraWulf claims to use sustainable energy sources for Bitcoin mining, countering environmental concerns with its zero-carbon nuclear and hydropower practices.

Pan is engaging with critics on social media to address the backlash from his speech and has expressed a willingness to learn from the experience.

Despite standing by his speech, Pan admits he would consider a more traditional approach in retrospect.

Ohio State University has not yet commented, and Pan is preparing a letter to students and parents to further address the incident.
