Monero is the most widely recommended cryptocurrency for Tor users. Every Monero transaction is private by default - ring signatures hide the sender, stealth addresses hide the receiver, and RingCT hides the transaction amount. There is no transparent mode; privacy is mandatory for all transactions on the network.
Monero has native Tor support in its wallet and daemon software. Configure the SOCKS5 proxy to route through Tor, and your Monero activity is invisible to network observers. Several Monero remote nodes run as Tor hidden services, allowing you to sync your wallet without revealing your IP even if you do not run a full node.
Monero is accepted by most privacy-focused services, including AnubizHost, VPN providers, and domain registrars. Its liquidity is high enough for practical use, with availability on most non-KYC exchanges and peer-to-peer trading platforms like Haveno.
