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.

Here’s what happened: Late Friday night, Milei fired off a tweet lending his support to a cryptocurrency token called $LIBRA. Milei described the coin to his nearly four million followers as a “private project dedicated to encouraging the growth of the Argentine economy,” claiming that it would be “funding small Argentine businesses and ventures.”

Argentinian president Javier Milei is facing calls for impeachment and a possible criminal investigation for his role in the rise and fast collapse of a memecoin.
