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!
It is true that Google has not banned bitcoin advertisements. They are concerned about the shady alt coins only as allowing those ads can hamper their image. They also do not want their uses to fall for these scammy offers.
However, a new person or someone with less knowledge about crypto will not be able to understand this. When they listen then news that crypto advertisements are being banned, they will think that bitcoins ads are also getting banned.
