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!
There wasn't any bitcoin related ads to being with so google could ban, bitcoin never needed advertisement, however i do get why they banned the other cryptocurrency related ads, ever since these ICOs started becoming popular all that i could see on Youtube on websites and everywhere where there is google ad sense is cryptocurrency related stuff and they have been driving me nuts, even though i am actually interested in those stuff, so imagine how it is going to be for a normal person.
