Worldcoin, initiated by Sam Altman, is now available in the United States. This innovative project offers free cryptocurrency to individuals who participate by providing iris scans. The initiative aims to create a biometrically connected network of users.

This development marks a significant step in the intersection of biometric identification and cryptocurrency, potentially setting a new trend for similar initiatives. The rollout in the United States represents a strategic move, leveraging the country's robust tech landscape to further Worldcoin's goals.
