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.

If that is really the case, then it may have such a profoubnd and negative effect on the cryptocurrency market, most especially, in the ICO market where one of the campaigns is promotion through social media. However, I do not exactly think thay facebook is aiming to ban such activities; I think that they are just limiting unwanted and trash contents filling their system, after all, the promotions brought about by the ICOs are still traffic they can exploit.
