Thanx.
Of course, we know about cointraffic.io -- and now we began to advertise there.
CPM = 5 euro, CTR ~0,3% (it's the best our result) -- so one click costs ~1,6 euro
It's not quite cheap. And traffic is too cold for convertion...
Cointraffic -- is the best ad system in cryptomarket, but Google Ads should be better.
You are paying too much. Using influencers we usually see below $1USD (0.88 euro) CPC. Also, when you advertise via influencers its much more personal than a banner ad on a news site.
