Walmart Inc said on Monday that a handout regarding the retailer’s partnership with cryptocurrency litecoin was fake.

A spokesperson for the corporate told Reuters that the discharge “was not real”. Litecoin didn’t immediately answer Reuters request for comment.

The fake statement said Walmart would allow its customers to form payments with litecoin at its online stores, sending litecoin prices up the maximum amount as 27.4%. It quickly gave up most of these gains and was last trading up about 5%.
