1. Social media is how I discovered blockchains like Steemit! It's sad Facebook is trying to put a death grip on advertising cryptocurrency and blockchain but there's more than one way to skin a cat.

2. I believe it effects it positively and negatively. Positively because Facebook is banning advertisement on Crypto. If you ban something and people find out what it is, they'll be more interested in learning more. Negatively because the FB platform allows posts on crypto only when people in the mainstream are involved in it.
