For anyone looking for recommendation to use this site for advertising, here is my honest review:

It's the most accomplished crypto advertising site I have seen. The dashboard is user friendly and in fact the whole service is very customer friendly.

HOWEVER, this does not deter away from the fact that my budget disappeared without any conversion. I know this as I used them for geo-targeting. All users that signed up were time-wasters and/or maybe opportunists. There is absolutely no quality control on the clicks. Once your budget is on there (and there's a minimum you can deposit), it's too late and you need to go through it.
