Monero
Secure, Private Digital Currency
...With Monero you are your own bank, you control your funds and can spend safely. No one else can see your balances, track your transfers or any other transactions unless you allow them to.
Monero uses ring signatures, ring confidential transactions, and stealth addresses making it absolutely private and untraceable. No transactions can ever be linked to a particular user or real-world identity. And because it is private by default, it is fungible or mutually interchangeable, and cannot be blacklisted due to their association with previous transactions.
