Argentine President Javier Milei is facing a corruption probe into his promotion of a meme coin, which is a highly speculative form of cryptocurrency that’s seen a recent surge in popularity after President Donald Trump and his wife launched tokens of their own.

An estimated 86% of crypto traders that took positions in a memecoin endorsed by Argentine President Javier Milei on Friday ended up losing money, according to research firm Nansen.

The budding scandal in Argentina has been dubbed locally as “cryptogate” and has links to a diverse cast of characters, including a high-profile U.S. influencer, a crypto developer who uses the pseudonym “Meow,” and a 28-year-old American entrepreneur who said he helped launch first lady Melania Trump’s meme coin last month.
