#BigTechStablecoin explains the concept of stablecoins issued by large technology companies. A stablecoin is a cryptocurrency whose value is linked to a stable asset, such as the dollar. When a BigTech company — like Meta (formerly Facebook) with its failed Diem project — launches a stablecoin, it combines financial stability with the massive reach of its platforms. These initiatives aim to facilitate instant and low-cost global payments, but they face regulatory challenges, privacy concerns, and economic control. BigTech stablecoins could transform finance, but they also pose risks related to monopolies and mass surveillance.
