If we talk about anonymity in cryptocurrencies we have to mention Monero. It was created at the beginning of 2014 and until recently it was considered the most private cryptocurrency of all.
Contrary to the great majority of cryptocurrencies this one does not use the blockchain as a protocol. Its creators opted for CryptoNote, a cryptographic protocol that reveals neither the sender nor the receiver nor the actual transferred amount, so we can consider that it has zero traceability.
The XMR, as Monero is known, is minable and, as with other cryptos, the total number of maximum tokens in circulation is infinite.
