Damn, isn't this just me? I'm totally guilty of the first two points 😂 Dual circulation of funds 😂 - Foreign exchange circulation: racking my brains to spend foreign currency domestically, and then trying every possible way to spend RMB abroad; Card collection: getting a bunch of useless domestic cards, then a bunch of useless foreign cards, then a bunch of useless U cards, ultimately letting money jump back and forth between these useless cards; - Cryptocurrency: loving to spend BTC, loving to spend USDT, scrolling to the bottom to see if CryptoPay or U cards are supported before buying anything; - Payment hassle: WeChat and Alipay are always linked to foreign virtual cards, and PayPal is linked to various mainland debit and credit cards. ㅤ Learning from small telecom operators about SIM, eSIM, and virtual numbers 😂 - SIM card enthusiasts: Obsessed with buying all sorts of strange physical SIM cards, or collecting various useless eSIMs like stamp collectors; - Data paradox: Using eSIMs and SIM cards from various countries while roaming internationally; - Virtual number addiction: Even after being banned from registering by various platforms, still researching various virtual numbers, ultimately paying off the virtual cards they've been using for who knows how long.
