Oh, the bad news is, they would only allow regulated/verified exchanges to use their add platform. Meaning - You want to advertise your crypto platform through google? Get your shit verified.
how is it a bad news?
have you forgotten what has been advertised on google before they banned it? let me help your memory: lots of scams including ICO scams, shitcoins, scam websites, malware stealing your private keys, shady businesses doing illegal activities,...
if you have a legit business ("crypto platform") you wouldn't mind verifying it properly. it is only scammers who will be screwed.
