I'm not sure if google to ban crypto marketing, because if so it seems google will lose revenue and be a loss because all activities related to ICO and crypto currency is dominated and supported and allowed by google. many places digoogle about the development of ICO and crypto let alone advertising about crypto marketing, because google is one of a good connector and puller to increase the number of investors, google media best ICO, therefore will loss if google out of the contribution, everything is related.
