I believe the chance of making it big in crypto is high as it is already backed by solid company, which is Facebook.
So no doubt, they can initiate their developments even without holding ICO, IEO or any crowdfunding campaign for that matter.
But we still need further information on how this coin will have an impact in the crypto industry or what difference would it give to the community...

Well, we still can't say where it is heading until we see them rocking and operating already. I've read also that it's likely Mark Zuckerberg will be teaming up with the Winklevoss twins.
