There are numerous cryptocurrencies that have the main goal of providing a high level of encryption, privacy features, full anonymity, and being truly untraceable. However, one of the most popular and the largest cryptocurrencies that can do this is Monero (XMR), which has technology developed that can help anonymize users. Monero transactions are much more difficult to trace due to the fact that they utilize ring signatures as well as stealth addresses, methods that help hide the identities of both the sender as well as the receiver.  Furthermore, Ring Confidential Transactions, or RingCT, aid in the process of concealing the transaction amount, which leads to a much higher level of privacy as well. Other secure and privacy-oriented cryptocurrencies include Zcash (ZEC), Dash (DASH), Horizen (ZEN), and Verge (XVG).
