MONERO should be on the list.
Monero is a secure, private and untraceable currency. This open-source cryptocurrency was launched in April 2014 and soon spiked great interest among the cryptography community and enthusiasts. The development of this cryptocurrency is completely donation-based and community-driven. Monero has been launched with a strong focus on decentralization and scalability, and it enables complete privacy by using a special technique called ring signatures.
With this technique, there appears a group of cryptographic signatures including at least one real participant, but since they all appear valid, the real one cannot be isolated. Because of exceptional security mechanisms like this, monero has developed something of an unsavory reputation; it has been linked to criminal operations around the world. Nonetheless, whether it is used for good or ill, theres no denying that monero has introduced important technological advances to the cryptocurrency space.
