The text says "at over 38 million merchants worldwide" which seems to imply that it isn't limited to the US in the sense in which you want to change the title.

The card works both in the US and at merchants that accept Visa abroad!

but is only available to US residents, of whom less than half own a passport, so the worldwide merchant aspect is applicable to the subset of the US population that hold bitcoin and a passport.

> but is only available to US residents

Who live in one of 24 states. New Yorkers need not apply.

Even smaller, I commend their ability to offer new services but it should make it clear that this is a very limited offer.

> Anywhere in US

Only in less than half of the US states (they use the number "24" prominently, which is still less than half, but include DC and PR, and CA is limited to 1000 users, so 21 is a more realistic number).

I've taken money out using Shift in China, South Korea, and Japan before they introduced exchange rate fees. It works anywhere VISA is accepted.
