How does a card crypto exchange work?
Could you elaborate on the operational mechanism of a card crypto exchange? I'm curious to understand how users can buy and sell cryptocurrencies using their debit or credit cards. Does the exchange facilitate direct transactions between buyers and sellers, or does it serve as an intermediary? Are there any additional fees involved when using a card to transact? Additionally, what security measures are taken to ensure the safety of user funds and transactions? Your insights would be greatly appreciated.
