First, it was Facebook who banned it.
Now, Google joins in the fray. Wonder who will be next?
What exactly is their concerns? Are they worried that they couldn't jump onto the crypto bandwagon? Thus losing market share?
Nobody else, or at least it wont matter because Google and Facebook are taking the lion share of internet ads. I think that this ban will have little-to-non impact over crypto currencies, because ICO's are not relying on traffic for FB & Google anyway.
