What are the differences between the following stablecoins, USDT, $USDC , and FDUSD?

USDT, USDC, and FDUSD are stablecoins linked to the dollar, but with key differences. USDT (from Tether) is the most used and has high liquidity, although it has received criticism for its lack of transparency. USDC (from Circle) is more regulated, fully backed by reserves and audited, which generates greater trust among institutions. FDUSD (from First Digital Group) is newer, backed by cash and Treasury bonds, and has gained usage on platforms like Binance. All aim to maintain a 1:1 stability with the dollar, but they vary in transparency, regulation, and level of adoption, which influences their reliability and usage.
