When your home bank card continues getting denied, what is the simplest way to pay for hotels or Uber overseas?

I frequently experience this when traveling. The transaction is rejected, the card is flagged, and the bank must be contacted from a different time zone. truly draining.

began storing cryptocurrency as a backup just for this purpose. discovered a crypto platform, which offers travel and mobility gift cards that can be purchased using cryptocurrency and sent instantaneously to Hotels.com, Uber, and airline platforms.

Thus, in the event that my card is blocked, I can obtain a Bitcoin or Ethereum gift card and complete the reservation without having to deal with the bank.

Does anyone else use this as a backup plan when traveling? I want to know if this is a frequent workaround or if there are better choices.
