Former UK Prime Minister Boris Johnson has controversially labeled Bitcoin a “giant Ponzi scheme.” Johnson argues its value relies solely on new investors, a claim frequently debunked by experts.

Johnson cited a personal anecdote of a £500 Bitcoin investment losing £20,000, attributing the loss to fees and confusion. However, such scams are not unique to crypto and occur in traditional markets due to bad actors, not asset structure.

Johnson also questioned Bitcoin's intrinsic value, comparing it to physical assets. Experts counter that Bitcoin's value stems from its scarcity (limited to 21 million coins), decentralized design, and global transferability without intermediaries.

Economists state Bitcoin does not meet the definition of a Ponzi scheme, which requires a central operator promising returns and paying early investors with new funds. Bitcoin is open-source, decentralized, and has no issuer or guaranteed returns. Its price is dictated by supply and demand.

Studies by organizations like the World Bank and the Swiss Federal Council have concluded Bitcoin cannot be classified as a Ponzi scheme. Johnson's arguments fail to recognize Bitcoin's operational mechanics and its sustained growth for over fifteen years.
