I don't see the Coin card as a MS gold mine. Sure your name will be on the Coin card, but I've never had a problem using gift cards to load money onto BlueBird. I'm thinking others are using gift cards to buy money orders and stuff and that's where you're worried about not having your name on the card?
When someone says "unloading gift cards to Coin" you're not unloading ANY money to the Coin card like you would with BlueBird. The Coin card is simply just combining all your cards in to 1 magnetic strip card. I'm sure we're all aware of this, but just wanted to clarify.
Lastly, the Coin card can only hold up to 8 cards at a time. Each card you add you have to take a picture of it, and then you have to verify a charge on the card. To me this sounds like it might be too cumbersome if you're trying to do gift card after gift card. How do I know you have to verify a charge each time you add a card? I watched it in the videos that have been getting released to pre-order customers only.
