user89462: How do crypto credit/debit card provider organise their crypto to fiat exchange process?
I thought that they would manually exchange crypto to fiat on exchanges through a bot. However, this would not be instant, right? Even if they used an exchange that allows "market trading" and a bot doing the exchange, I cannot see how that would be instant.
Any ideas how the card providers solved the problem?
EDIT: Could it be that they buy crypto in bulk, thus there does not happen an exchange at the very moment (probably OTC)?

user91060: there are many card provider services. Wirex is one of the popular bitcoin debit card provider. I found this article with list of best bitcoin debit card providers 
There are exchanges inbuilt within the wallets to convert cryptos into eachonther as well as they support crypto to fiat exchange.
