I'm frankly a little disgusted that you think your community would stoop low enough to want to go near any blockchain/crypto garbage site just because theres a free game there. Further disgusted that you think it's okay to just advertise for them uncritically as well.
I'm aware the post was also a test of the waters due to the invitation for comment. So here's my comment: DON'T. Please. It's all snake oil crap and the gaming community at large is against it all. No one is interested in going near that stuff. Get it off the site.
