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!
Google should not ban bitcoins because if they do then there will be no more cryptocurrency who's going to be advertised on different sites since their google adsense is the best way to advertise cryptocurrency on different sites all over the web.
