I think/hope that was just a joke.  Conspiracy theories aren't always crazy, as conspiracies do exist (I'm not talking chemtrails...but people conspiring to do something without others knowing about it).  However, if Paycoin is built to be appealing to banks, I don't expect that it goes much deeper than exactly that...being built to show banks that cryptocurrency can be developed in a way that they can exploit.  It may have a banker (or a small group of bankers) already involved, but who knows for sure.

The potential consequences is what worries me about this idea, along with at least some connection between Josh Garza and a high level investment banker.

In my opinion, that logo looks like a stylized, metallic H  

Edit:  Or, maybe a stylized, metallic H on a gold and silver "Captain America"-style shield.  I have to say, I actually like that logo more than the Paycoin logo.
