The former British Prime Minister's view that "Bitcoin is a Ponzi scheme" has sparked controversy, while Michael Saylor emphasizes that BTC is decentralized and has no issuer

Former British Prime Minister Boris Johnson posted on the X platform expressing his long-standing suspicion that Bitcoin is a "massive Ponzi scheme," and stated that recent cases of investment losses he has heard about have made him more concerned that this judgment may be correct.

In response, Michael Saylor, founder and CEO of Bitcoin treasury company Strategy, disagreed with this viewpoint. He pointed out that Ponzi schemes typically require a centralized operator to promise returns and pay early investors with the funds from later investors, whereas Bitcoin has no issuer or promoter, and there are no guaranteed returns; it is merely an open decentralized currency network driven by code and market demand.
