Facebook announced that it will now allow cryptocurrency advertisements. But they place a strict compliance on ads that are allowed
The company says it will allow ads and related content from pre-approved advisers, but will still not allow ads promoting binary options and initial coin offerings.
It mentioned that it has to apply first before they can be allowed to advertise. And they have strict limitation on the applications in order to avoid facebook from being used by scam projects.
I hope this is true, here's the link to the report.

It's like showing that crypto has a big influence on other industries.
