Facebook has been very vocal about its stand on fake news. They even released a statement that they will have a thorough filtering towards this. In my own point of view, Facebook is not against bitcoin. It may have a possibility of blocking advertisements about bitcoin but it doesn’t mean that they’re against it. They are only preventing possible scams about the said cryptocurrencies. It’s also helpful that way since we can be protected from future problems of these scams.
Facebook with its all ad platforms (FB, Messenger, Audience, Instagram) is the most profitable way to advertise your product on the internet. It has reach to millions of users, and it costs a little. Of course, by banning crypto projects on this platform it leads to stagnation for some of them. You can not say that they are not against crypto. Yes, they do!
At least they could impliment some sort of admin moderation! But they don't!
In addition to this, they are trying to moderate the market before the goverment. It is not only looking funny but also comfirms that they are against crypto.
