Coins using coinjoin protocol for anonymity will fail because coinjoin isnt anonymous at all. Darkcoin is using coinjoin. Monero had problems with bloating the blockchain, dont know is it solved or are they also coinjoin based? Razorcoin isnt really a competiter ? What about XC I know they failed at their first try also on their second ? Crypt and voot are just scam coins . Cloakcoin is already anonymous but only using exchanges, now the big thing is coming POSA a innovative way for private transactions after that decentralized market.
