Facebook has only banned the paid advertising of cryptocurrency. Which is fine as I get sick of seeing them when I do occasionally jump on Facebook. You or anyone else can post or share crypto stuff on your timeline so bounties etc will not be effected.
So as long as you don't make a paid ad for cryptocurrency nothing changes.
The greatest ban of these ICOs and crypto advertisement will affect the market, but just a little bit. By the way, it is also prohibited to share this information in Instagram. Folks will use Telegram and YouTube channels more now.
