I do happen to agree with that. People just make themselves happy with the thought of them spending their coins through whatever debit card, but in reality it's just them settling transactions with fiat. I however have to point out that if you have Bitcoin as only source of income, these cards will allow you to basically shop anywhere in the world without the need to convert any of the coins you have yourself. In that regard, it does serve a purpose. The only downside is that you depend on a third party, and that's not exactly a thought I am very happy with.
Other than that, the video included in this article made me almost fall asleep. Could they not pick someone who's more energetic to get the conversation running in a more interesting way? Damn.
