Peter Schiff, a longtime Bitcoin critic and gold advocate, recently labeled Bitcoin a “sh*tcoin” while arguing it has underperformed gold, silver, and major U.S. stock indexes over the past five years.

The remark came amid a heated exchange with MicroStrategy’s Michael Saylor, who highlighted strong Bitcoin-related gains.

Schiff escalated by publicly challenging Saylor to a formal debate on Bitcoin’s merits, inviting a moderator and claiming it would expose the cryptocurrency as a volatile bubble destined to crash to zero.

This latest flare-up underscores the enduring rivalry between Bitcoin maximalists and traditional asset proponents like Schiff, who has predicted Bitcoin’s demise multiple times since 2011.$BTC
