Even though Google is illuminati trash, I somewhat get their policy. It's probably too difficult to tell what is a scam and what is legit with unregulated ICO's and they don't want the bad PR when some of these shit coins go to 0. True cryptocurrencies like Bitcoin (and Litecoin) don't need advertising. (I'm starting to like the idea of Litecoin as my spending currency, bc I never want to part with Bitcoin, so I wouldn't spend it, but I would spend Litecoin).
