Do you really think a small anonymous team is going to be able to hook up with a major debit card provider?  And how are they going to handle instant payments/debits?  This is no small feat from a technical perspective, just look at ETN and Graft as examples.  And their whitepaper is totally lacking in real information.  Who is "Phil Reynolds"?  His last name wasn't even listed on the bitcointalk thread initially IIRC, it was added later.  Is there any way to verify his name?  Why not post a link to his LinkedIn page or something?

If I were going to design a scam coin it would look very similar to this.  So far the market agrees with me.  Just look at the trades and volume on Trade Ogre.  Every day more XPP is dumped than could possibly have been mined and with almost every sale the price drops further.  The bulk of volume has to be coming from the pre-mine.  Of course the team could easily refute this by publishing the view keys.
