Right! Facebook is forbidden to advertise bitcoin and what is related to bitcoin. That affects bitcoin. But I do not think too much. If bitcoin builds trust and safety for players. They will find themselves bitcoin. No need to go through facebook.
But it can not be denied that advertising on Facebook is very profitable, although it is not the only way. Many projects are fake and scam so many Facebook users who complain, it's natural. The impact is quite large related to public confidence, so the allegation that the dangerous cryptocurrency is getting bigger. All we have to do is stay calm, as you say, it will end soon and the market will rise again.
