So as you might have already heard, Facebook has taken a step against crypto ads asking people to participate in ICOs etc.
it is perfectly understandable that Facebook banned these advertisements, specially the ones involving ICOs because they are illegal at heart and the way of raising funds through an initial coin offering has never been a legal method. not to mention all the scams that are happening through these!
Is this bitcoin value fall an affect of this ban by FB?
no it has nothing to do with that. nobody cares when a platform like FB changes their advertising rules!
the recent drop was purely market manipulation and FUD.
