About Monero:

Monero is the leading cryptocurrency focused on private and censorship-resistant transactions.
The majority of existing cryptocurrencies, including Bitcoin and Ethereum, have transparent blockchains. Transactions can be verified and/or traced by anyone in the world. This means that the sending and receiving addresses of these transactions could potentially be linked to real-world identities.
Monero, on the other hand, uses various privacy-enhancing technologies to ensure the anonymity of its users.
