• Michael Burry, Paul Krugman, Mark Cuban, Jim Chanos, and others have shared their views.

Bitcoin, ethereum, and other cryptocurrencies have plunged in value in recent weeks, sparking a flurry of comments from critics, proponents, and other market watchers.

Michael Burry has underlined bitcoin's volatility, while Paul Krugman and Jim Chanos have seized on the crypto crash as evidence the industry is built on hype and speculation, and best seen as a hotbed of fraud, corruption, and predatory behavior.

Meanwhile, Suze Orman has warned crypto fans to be careful buying the dip, and Tom Siebel has predicted that plunging coin prices and soaring living costs could drive crypto workers back into traditional jobs.
