To be honest, Cryptocoins don't really need facebook ads to work anyway. People will hear about it one way or another, and the fact that Facebook even needs to ban them, means that their popularity is greater than ever.
They don't want people hoping into the space before they offer their own: A) P2P Wallet B) Exchange C) Coin/Token
Get ready guys , Fb will create their own cryptocurrency in coming days .
The show is just beginning , we are blessed to posses cryptos .
