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.
Totally it will not die, the life of crytocurrency is not from any social media it is from the team strategies and investors but we can't deny the fact that after all of this, still it will decrease the possibility of reaching the potential investors.
