I wouldn't use it.
It would be centralized, not truestless, transactions could be reversed and it could not be used worldwide, so what's the point?
You might as well just use FIAT then, there are no benefits for using crypto debit cards if you already have a bank account and a card. It would essentially be just an overcomplicated crypto>FIAT trading platform for users who intentionally give up all the major benefits of crypto.
Cool. Some people have told us that they want to use those cards to quickly liquidate crypto into fiat (even if it comes with a slightly higher fee) since it sometimes takes days or weeks to get fiat out from an exchange. Does that make any sense to you?
You don't take his word as right info. There are very few people takes the crypto card as centralized and more trust than bank cards that is not true at all in my perception. Most of the people want to avoid the fees between the multiple transaction.
Then as you said, it helps to liquidate the BTC to fiat. No need to bear the deposit or something on exchange wallet. General use of card on local places we need more BTC ATM on the concern city and region.
