When I topped up my crypto debit card for the first time, I was a little nervous too, but it turned out to be simple. Basically, you log into your account, find the card section, and choose the “top up” option. Then just select the crypto you want to use and the amount. It gives you an address or a QR code to send your funds. The whole process takes a few minutes, and you’ll get a notification once it lands on your card. If you want more details or screenshots, there’s a clear guide at
