Realized something at a Lisbon bakery this weekend about what my crypto card "balance" actually means

The author had an experience at a Lisbon bakery where their Crypto.com card was declined, making them realize the difference between self-custodial and non-self-custodial crypto cards. They learned that the balance on a non-self-custodial card is just a claim against the platform, not actual custody of funds. The author now views self-custodial cards as having a more subtle benefit.
