Facebook bans all crypto-currency ads

It's understandable but a lost cause. The actual inclusion of ads in general are pretty legitimate since if you own the most product, then you'll be able to afford the ads unlike those who are trying scam or claim false statistics of their "business" through these ads.

It's a simple understanding of business and human nature, and like PenilePunisher stated above, this really is like a gold rush, except this is at everyone's fingertips.
