Ever since Infini shut down its U card business, I've been applying for any good U card I come across. 😭 Because I don't have overseas ID, I haven't been able to try the EtherFi cash back feature recommended by my group members. Currently, the two cards I'm using the most are the Bybit card and the Solayer card. The former offers a 2%-10% cash back bonus depending on your account level, but its use cases within mainland China are quite limited. So far, I've only been able to use it for GPT renewals and Apple Pay outside of mainland China. The latter offers the advantage of covering everyday small purchases, such as food delivery and taxi rides, and automatically earns Emerald Points with your purchases. However, it occasionally doesn't work when subscribing to Twitter or other platforms, and the biggest drawback is the 1% processing fee for top-ups.
