I never use such card, simply did not have the need for it, and I have few local exchanges in my country where I can very easy buy / sell crypto without too much complication (no KYC). As others pointed out it is all about how card providers set rules of the game, and it is also how those who regulate them are setting rules.

I would like to see (as many others), more merchants who will accept crypto, even if they use intermediaries like BitPay. But in that case users of cryptocurrency would be less dependent on card providers like Visa / Masterdcard to convert crypto in fiat.

I know that Wirex is most used recenty, is someone using this card maybe? https://paycent.com/
