It is not crypto related, and I'm noticing that all the alternatives are just for crypto related contents blogs. I'm afraid I have no choice to stay with adsense
I've looked around a bit in the A-Ads platform, although not from the point of view of the publisher but of a potential advertiser. When you create a campaign (you don't have to register, you can simply try it out), they offer traffic explicitly also from non-crypto sites, like entertainment, (non-crypto) finance, adult, "community sites", blogs, Goods and Services, Technology and even Science and Education. The pricing model seems to heavily favour sites which are visited by other visitors than the typical crypto audience, because only one impression per IP counts for the share you get from the rates (see
this thread). So maybe it's worth a try.
Unfortunately, for other reasons (no CPC pricing model is offered, only a variant of CPM with "unique impressions") it's not the platform for my needs so I can't provide experiences, and I've also not used it as a publisher.
