Hmm This really might just be the a hot site. I've been seeing ads of it offsite on crypto related sites. This thread has 40 posts in 2 days so the site seems to be gaining traction.
OP, you site has a Nice UI and color scheme btw
If you look at their site stats, it shows the accounts is at 620.24k already. That's actually huge number. But we don't know the number of active players from that number. However, this may be reason why we are seeing their ads outside the forum before they decided to create their thread here. They already captured a lot of players. Won't be surprised if they will not run any promotional campaign here in the forum but would be nice if they do.
