This may affect the new incoming coin marketing process, but we still have other ways to tell people about cryptocurrency. Facebook may see the negative side of ICO, I can feel facebook sentiment because not all or most of ICO is shady and only focus in making profit. They may think that they are used by the shade, the sad thing is that there is an ICO that is worth the investment and holds many promises in the future. Hope they will change their minds and turn things around for the benefit of the entire ecosystem of cryptocurrentcy.
Facebook is one of our ways to promote bitcoin. It's is way easier to tell people about cryptocurrency since most of the people has a facebook. It's a big loss for cryptos now that facebook banned bitcoin and ICOs. It's a big loss for those investors and believers of bitcoin.
Anyway, there's still other ways to promote crypto in social media. And I am also hoping that the founder of facebook and the entire team will change their minds about cryptocurrency and see the positive side of it.
