Facebook and Instagram bans Cryptocurrencies ads. I think they are nothing to cryptocurrencies. Facebook users are not great market. It is only few percent of ICO market. I think cryptocurrencies will not die because of them.
Facebook and Instagram doesnt have any connection to our market,they are just promotional platforms for these ICOs,we do not need them to survive,cryptocurrency market will surely become more relevant to most of the people in the future,youtube will be more open for the promotions of these ICOs,thus to what i have read facebook prohibited paid advertisement of these ICOs but it doesnt mean that they will ban all the account that shares or promote ICOs using their own profiles.
