#BigTechStablecoin is a stablecoin issued by a major technology company such as Meta, Google, Apple, or Amazon. Unlike traditional stablecoins (e.g., USDC), they rely on massive user bases and Big Tech infrastructure. An example is Meta's Libra (Diem) project, which was shut down due to regulatory pressure. Such coins promise fast and cheap payments directly within applications, but raise concerns: centralization, data control, financial influence over states. Although there are currently no direct launches, interest remains—especially with the growth of Web3 and digital currencies. This is potentially a new stage in the evolution of digital money.
