I think if we use such a card it is very good, and it is very useful for us all, and I myself am very happy to use the card because it can help for future success.
The problem is not in the use because we all know this is going to break barrier between the traditional banking and the cryptobank but the problem lies on the providers of this card. they are not interested in given out cards to unregulated cryptobank because of the issue of scam and money laundery which many have said cryptocurrency promote. when you listen to many peoples comment here on the thread you will realized nobody have said it emphatically that they are making use of the card despite the fact many ICO goal are centered around debit card provision. AMON, MONACO, kurecoin and many other ICO are still targeting this project
