#BigTechStablecoin crypto projects involve tech giants creating or backing stable digital currencies, typically pegged to fiat like the USD. These stablecoins aim to enable fast, low-cost global transactions across platforms such as social media or e-commerce. Examples include Meta's Diem and PayPal's PYUSD. While promising for financial inclusion and innovation, they raise concerns over data privacy, regulatory oversight, and the concentration of economic power in Big Tech hands.
