Here's what Google said:
https://support.google.com/adwordspolicy/answer/7648803My first comment is that there's never been any
BTC advertisement. Who would pay for it? The
BTC's foundation? This board's webmaster? As there's no corporation, nor an individual owning
BTC, there can't be any kind of advertising. The only ads I've ever seen were for lousy ICOs, shitcoins, trading and exchanges websites where you can make a deposit but not a withdrawal, trading consultants who screw you with the promise to show you how not to get screwed, and super safe crypto-wallets where your private keys are automatically sent to a smart angel in East Russia. Google wants to ban all that? I say thanks Google!
I agree that these advertisement bans are for ICO related programs, Bitcoin popularity started as a word of the mouth and the inception of these scams ICO started to cast negative feedbacks on the cryptocurrency community, there should be a regulation on this ICO in the future.
