Former British Prime Minister Michael Saylor's view that "Bitcoin is a Ponzi scheme" has sparked controversy: Saylor emphasizes that BTC is decentralized and has no issuer.

PANews reported on March 14th that former British Prime Minister Boris Johnson posted on the X platform, stating that he has long suspected Bitcoin is a "huge Ponzi scheme," and that recent reports of investment losses have further fueled his concern that this assessment might be correct. In response, Michael Saylor, founder and CEO of Bitcoin treasury company Strategy, disagreed, pointing out that Ponzi schemes typically require a centralized operator to promise returns and use funds from later investors to pay earlier investors. He argued that Bitcoin, however, has no issuer or promoter, and offers no guaranteed returns; it is simply an open, decentralized monetary network driven by code and market demand.
