Too many hidden users lately
Well being crypto you can't really be surprised people are keeping their username's hidden. Honestly why become a target by showing your whale status. There are so many flaws these days with certain security measures such as Windows exploits, 2FA SMS scams, public dox-ing, etc that people rather keep themselves anonymous.
I think if someone maybe used a unique username to Primedice then they could show off their stats however that still poses a threat because their PD account could get compromised and become a target. I got great security and keep everything on cold storage but I still become paranoid from time to time about my BTC holdings. And keeping your BTC on an exchange or casino is even more risky.
Plus, it is a thing that the casino offers so there is no reason why we shouldn't use it neither, as long as its offered anyone can take up on it.
Another thing would probably be "do not list me anywhere" type of thing that would mean you would not be hidden if you don't want to (could still be hidden too if you want) but also not get listed on high roller things and competitions and so forth which would make the security a bit more.
