yeah, the card is a cool feature but must have some limitation, kyc process and stuff, anyway I wouldn't switch to some new exchange from my old proven ones
If the card is actually the only one cool feature that makes it stand out than other exchange then it might be a problem tbh. as you said the card is cool feature but in the past many crypto card provider just got bankrupt when the issuer of the card gone. Not to mention that any most of the popular exchange right now already has this crypto card feature ready to go and is reliable. New exchange should work on their reputation ,trust and reliability first honestly.
