Cryptonote is very promising and any fairly launched coins using cryptonote are worth having.
Not just any fairly launched coin using Cryptonote. A Cryptonote coin without a tail emission is very vulnerable to becoming insecure when the block subsidy runs out or becomes very small. Cryptonote scales the blocksize by imposing a penalty that is dependent on the block subsidy. Make the block subsidy zero or insignificant and there is no penalty. This creates an effective infinite blocksize. My take is that Bytecoin will provide an early warning of this precisely because of the pre-mine / ninja-mine. Instead of the classic "canary in the coal mine", one can think here of the "canary in the pre-mine / ninja-mine".
There is a reason why Monero has a tail emission.
Edit: On the related issue in Bitcoin the "small blocksize crowd" in Bitcoin also make a very valid point because of the above issue, since Bitcoin, without a tail emission, needs to create a fee market, likely by restricting the blocksize, in order to ensure the long term viability of Bitcoin.
XDN is a CryptoNote and has a min block reward = 150 XDN. Will keep it static and will try to never reach max.coin value because will implement rules like "1/2 fee burning and recycle".
