From the Bitcoin and Markets podcast:
Marshal Long is at it again. He is a legendary scammer in bitcoin and altcoins. He's been caught in so many lies, it's incredible that he has any credibility left to scam people. In this article, in the first couple of paragraphs he exposes this as another scam.
Here's more on Long from Bitcointalk https://bitcointalk.org/index.php?topic=1303147.0;all
Also noteworthy is that Long apparently did business with Garza during the GAW scandal.
