I remember those coins that said to be gold-backed up but never made it so special and popular. So when I hear a project that basically boasts of they are backed up by gold or some assets, I won't believe quickly unless proven and stably operating.
Exactly. I've seen a number of "gold backed" coins. I think that one was for real, but all the rest were fakes.
Basically that's also why I am wary/super-cautious about stable coins, I tend to put them in the same basket with these gold-backed coins.
