Only a few cryptocurrencies are oriented solely towards the privacy and anonymity of its users. The most prominent ones like Monero, ZCash, and PIVX are promise full online anonymity for their users.
A similar ban was suggested in Japan earlier this year. Anonymous cryptocurrencies are used for payments throughout Dark Web shops.
