Cutcoin is one of the projects that offers the best in terms privacy and annonymity. In terms of privacy all transactions are made private by default and in terms of annonymity, all transactions are untraceable from the amount of transaction to the balance in the wallet and lots more.
They achieved this through the adoption of a special form of proof of stake consensus algorithm that causes all transactional operations to be encapsulated and make it confidential.
The project also offers a staking pool where users can earn their token (Cut) as reward.
Projects like this is very good for confidentiality but it can also be misused by money launderers and internet fraudsters.
