Travel tip: don’t carry just one credit card, even if it’s an international card. Some places might not take your brand. Example: American Express is great but not accepted everywhere. Also have a visa or a Mastercard. 

Seems visa accepted more places. 

And be sure to get one with no Int’l fees or conversion charges.

Whatever your decentralized, borderless, neutral, censorship-resistant open blockchain question is, the answer is YES… to Crypto!

Last I checked every crypto card has crypto conversion fees baked in.  Even those who say they don’t charge take a spread on the crypto conversion.

For cards with no international fee, usually have to go with a paid travel or executive card.  Personally I have found unless you travel often it’s not worth the yearly fee.

That being said I am Canadian and have heard US cards have lower yearly fees so I could be completely wrong.
