I didn't really know what a Dolphin Card was, so I had to look it up:
The Dolphin Card is a privacy-preserving VISA® card that lets you spend your Bitcoin directly from AQUA. It’s primarily designed for online, in-app and over-the-phone purchases, but it can also be used in-store where merchants allow manual entry of card details.You fund the card by depositing BTC, L-BTC or USDt in your AQUA wallet to top up your balance. After two network confirmations, the amount you top up is converted into USD, ready to spend.Once you’ve added funds, the Dolphin Card works just like any other VISA® credit card. You can use it for one-time purchases or set it as a default payment method for recurring charges like subscriptions and delivery apps.
