Monero is the most significant privacy-focused cryptocurrency on the market. It was created in 2014. The main feature of Monero is mixing of transactions in the blockchain. Third parties can't see amounts of money sent in transactions and addresses participating in operations, so all payments are untraceable. The developers are keeping it ASIC-resistant. It saves this network from centralization and gives an opportunity for GPU owners to earn something from mining Monero.
