The core business of USDT / USDC is essentially the financial infrastructure of the crypto world. When the crypto world thrives, they thrive; when the crypto world declines, they decline. They can't exist without the crypto world. Stablecoins are a kind of crypto-dollar within the crypto space, not a globally legal currency. The claims by stablecoin companies about 'foreign trade settlement,' 'real-world applications,' and 'the future of payments' are all exaggerations and fantasies.
