Ok, so I've tried it.

For those who are interested:

-download and install The Bitcoin Company app (use a burner email). The app is not foss, I assume. You get some sats (1000 sats) as a welcome greeting.

- buy Visa virtual international gift prepaid card using lightning (maximum is 700 US$). I got few sats as a reward.

It generates Visa prepaid card and challenge token which you'll need in later step to display Visa card number, expiry date, cvv code.

There's a warning saying that you need to disable VPN before viewing your card (I DIDN'T switch off my VPN and it worked anyways).

In the next step you'll enter challenge token and afterwards your visa number, expiry date and cvv is shown

- now use separate phone which is NOT LINKED to your identity to add visa card to Google/apple Pay wallet

- then I went to the local store and paid with google pay, it worked😉

Besides visa prepaid card you can buy Amazon gift cards and many more (for Amazon, coincard, foundation devices etc.)

Not sure how the business model of The Bitcoin Company works and who is the yield.

Cons:

-visa card is denominated in US$, so if you use it in Europe, you're charged 2 % conversion fee 😠
