Seems that you are really new here in crypto. By any means you are not the very first project to have the gold backing. Did you know about Xaurum? They are one of those who are gold-backed projects. And so many others. But most of them were scammers and dead already. But claiming to be the first, I think is not right. Do your research first.
Perhaps you didn't read their white paper and/or understood it. I invested in their flash ico yesterday where they offered a small percentage of the total amount for sale early, and I made sure i understood it thoroughly before putting my money into it. They're the first to assign a gold value to each coin AND give you the option to trade X amount of auric coins for actual gold anytime after launch. After yesterdays sale, by my rough calculations of the gold price they already have somewhere close to $1M in gold accounts now against the coin issuance and the main ico is still to come. Yes ive seen others with so-called gold backing but Auric is quite different, imo anyway.
