For every site redirection from google adsense you paying money to google.

You also have a lot of business competitors on crypto exchange market.

There is a black competition trick which idea is to hire a few tenths of asian people which will registering on your site thousands times per months by CLICKING ONLY ADSENSE LINK. So that you pay to google a lot money for fake clients. E.g. for nothing. This also force you to stop promoting your exchange on google at all and you can lost real potential clients because of that.

Its just black SEO competition.

I am experienced web developer and can help you with protection from it. I have previously developed protection scripts from such type of fake customers attacks and adsense link abuse. It will costs but less then you loosing with adsense.
