Monero (XMR) is a privacy-focused cryptocurrency that is similar to other cryptocurrencies like Bitcoin (BTC) and Ethereum (ETH). However, Monero uses unique features to provide greater privacy for its users. For example, Monero uses ring signatures and confidential transactions to obscure the sender, receiver, and amount of each transaction. There are a few other cryptocurrencies that also focus on privacy. These include Zcash (ZEC), Dash (DASH), and PIVX (PIVX). Like Monero, these cryptocurrencies use features like confidential transactions and/or ring signatures to provide greater privacy for their users.
