Facebook is banning all ads that promote cryptocurrencies, including bitcoin, in an effort to prevent people from advertising what the company is calling "financial products and services frequently associated with misleading or deceptive promotional practices."

That means no advertiser — even those that operate legal, legitimate businesses — will be able to promote things like bitcoin and other cryptocurrencies, initial coin offerings — ICOs for short — or binary options, according to a Facebook blog post.

That also means that "crypto-genius" James Altucher, whose ads have appeared all over the internet and have become a meme of sorts for the entire crypto industry, won't be able to advertise on Facebook.

Ads that violate the company's new policy will be banned on Facebook's core app, but also in other places where Facebook sells ads, including Instagram and its ad network, Audience Network, which places ads on third-party apps.
