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)?
