I won't say "wow" because this project is not the only crypto project backed by gold (I mean I've come across several times). I suggest that you innovate by offering some advantages that other projects don't have, that way this project will attract a lot of investors' attention. apart from all that i am quite interested in crypto projects backed by gold.
You've heard of others that failed or something like PAX gold. If they weren't scams, I wouldn't make GRC. And the only indicator of how trustworthy is this project will be time. There is no need for utility or innovation. Gold stand the time and never failed unlike any other currency. So, we will see you on the other side.
