you forget to mention IOTA and Gbyte (byteball).
But wait a little bit, is this for real? IOTA used DAG which can create a zero fees transaction and instant transaction consider it eliminates the miners and replace it with the server. that looks so weird and you must create a comparison between any platform that working in the same field. Blockchain and DAG are different stories
Iota has zero fees, but afaik it is still depending on the coordinators and doesn't reward users who run full nodes, while x42 rewards users in the form of staking rewards and also for hosting dApps.
iota aims for IoT messaging and payments.
Gbyte(byteball) is not feeless?
Well is a good comparison, but if more and more developer will find a way like Nano did with captchas for distribution then maybe more people will be interested on a new coin. And there yes are already some coins like Nano and x42, IOTA and Gbyte.
Thank you,there is a bitcointalk airdrop going on for x42 ,i agree it will take some time for the platform to become more mature and encourage developers to build on it.
