[Caixin: Overseas U Card advertisements attract users to pay with USDT for ChatGPT, but domestic applications face legal risks] According to Caixin, the overseas bank card 'U Card,' which facilitates payments using the US dollar stablecoin USDT, has been advertising on platforms like Xiaohongshu to attract users to apply. Users can use the U Card to complete payments such as ChatGPT Plus subscription fees, converting on-chain crypto assets into off-chain purchasing power. However, applying for and using the U Card within China faces specific legal risks. Caixin pointed out that since 2023, Binance U Card has exited the European market, and other project teams like OneKey and Infini have also gradually shut down their consumer-facing businesses, indicating that the U Card industry is experiencing systemic challenges.
