Google has started accepting crypto advertising again and I'm sure the others will follow. Facebook is planning on releasing their own cryptocurrency and I'm sure Google is developing something similar.
Can you link to some proof that FB is developing their own coin please?
I know that coinbase ads are rolling on facebook, so they allow "crypto ads" as well. But it might be harder to get whitelisted there
The rumors of a FB aren't confirmed but there's been some strong hints, most insiders believe one will be coming up.
Also yes, Facebook has a whitelist to allow crypto ads but it's very very difficult to get there and they're very backed up because of the number of people applying to get whitelisted...I heard it took coinbase a few months to get approval.
