Bill Self, the basketball player's former college coach, narrates the latest commercial from the virtual currency exchange.

Mr. Self says in the ad that they kept going even when their path didn't make sense to everyone else.

The ad doesn't say that the market is in the middle of a crisis. People beware.

Hollywood celebrities and top athletes have been enthusiastic about the asset over the past year. Virtual currency was portrayed as a world with its own hip culture and philosophy, one that was more inclusive than traditional finance and that involved the chance to make loads of money.

The Super Bowl was nicknamed the "Crypto Bowl" because of the amount of ads that featured the industry, several of them starring boldface names.

After hundreds of billions of dollars disappeared in a sell-off this month, those famous boosters are under fire for helping vulnerable fans to invest without emphasizing the risks. The market forcryptocurrencies is volatile and rife with scam.

Giovanni Compiani, an assistant professor of marketing at the University of Chicago, has found that younger, lower-income investors tend to be overly optimistic about the future of cryptocurrencies.

So far, the celebrity boosters have been silent about their feelings about the promotions.

The company did not want Mr. Embiid to discuss his partnership with them. In a widely seen ad last year, Matt Damon compared the development of virtual money to the development of aviation and spaceflight, but he did not respond to requests to weigh in. No response from the basketball star, who was featured in the company's Super Bowl commercial.

The Oscar winner did not respond to a request for comment after declaring on her website that CRYPTO is here to stay. Gwyneth Paltrow, who won an Oscar last year, lent her name to a contest.

Paris Hilton, who has nearly 17 million followers on the social networking site, didn't respond to a request for comment. Although Mr. Brady and Mr. Rodgers still have laser eyes, they did not join several other famous crypto pushers. A representative for Naomi Osaka, the tennis star who became an ambassador for the FTX exchange this year, wrote in an email that she sadly is overseas and not available.

In FTX's Super Bowl commercial, Larry David derided the wheel and the light bulb before rejecting them. The ad urged viewers to not be like Larry.

The director of the Super Bowl spot said in an email that he and Mr. David didn't have a comment on the market collapse.

I don't think we have anything to add as we don't know how it works.

A famous person's endorsement may be memorable, but the actor John Houseman's spots for the Smith Barney investment firm decades ago are Madison Avenue legend.

They get offered money to promote something that has promise, and they are celebrities.

According to estimates from the advertising analytics platform Pathmatics, the average cost of digital advertising for the month of March was $109,000 a day. In May, that dropped to $24,669 a day.

Spending at FTX, one of the companies that most aggressively used celebrity promoters, has fallen to 14,700 a day this month from $26,400 a day in March, according to Pathmatics.

In an interview with The New York Times before the Super Bowl, the president of FTX's U.S. arm said that they had created an arms race. Mr. David, Mr. Brady and his wife Gisele, the golfer Albane Valenzuela, the basketball player Stephen Curry and the baseball player Shohei Ohtani are some of the famous FTX brand ambassadors.

He said that racing to grab all of the remaining properties and athletes is not their top priority.

The company is likely to spend a lot more on marketing, but is now focusing on reaching different demographic groups, such as digital campaigns and Google ads, he said.

He said that they are thinking of doing things a little bit differently than in the past.
