$ZEC $DASH $XMR
Private (anonymous) cryptocurrencies are digital currencies that hide transaction details (sender, receiver, amount) on the blockchain to ensure user privacy, unlike Bitcoin, where transactions are visible but linked to addresses rather than identities; popular examples include Monero (XMR) (uses Ring Signatures), Zcash (ZEC) (with zk-SNARKs), and Dash (DASH) (with the PrivateSend option). They provide better privacy but may raise questions among regulators and on exchanges.
