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!

On this trip we paid everywhere with a card of Ukrainian bank (Visa), it was very convenient. But it is better to have a cache just in case)
