Dear friends , please consider this innovation, maybe someone will help it!
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.
