Just happened to need a card for subscribing to AI. If it’s recognized as a US card, subscribing to AI works well—after all, most of our Claude MAX 20X accounts are probably already locked by now. The OKX card is like rain after a drought. Whether it offers cashback or not doesn’t really matter, since the main purpose is to use it for subscriptions. Having a US card and address is still super handy. From my years of experience in this game, for something like Claude, the strategy is to register on mobile and use it for a few days, then subscribe to the basic version on the web for a few more days, and only then upgrade to the 20X MAX version. This way, it’s less likely to get locked. You can join the OKX CARD waitlist here: https://www.(okx.com)/zh-hans/pay
