Privacy coin with transactions that are actually untraceable rather than just harder to trace like with most other “privacy” coins. First to implement Zerocoin protocol and driving force behind its development. Their white papers aren’t fluffy marketing pamphlets but actual academic papers. They will also be the first to implement “egalitarian computing” algorithm MTP that makes it close to impossible to centralize mining. Amazingly helpful and peaceful, no-FUD community and disarmingly honest and down-to-earth community and comms manager. No hype! Drawbacks are the not-so-user-friendly wallet, no light wallet and no hardware wallet integration but I understand it is being worked on so I can give 5 stars straight away.
