been watching Ludena Protocol. Its one of the best coins ive seen so far with an existing product (3 million users in Korea currently), just launched p2p gaming, and will be listing on a big exchange soon
Ludena is a good coin but the token is not yet launched or traded and we can't expect if that was good coin to invest because we will need to see the performance that will be made by ludena token after it will be traded on exchange site.
the project does look good. even in organizing campaigns they also pay their participants with ETH coins. although it's not big I think it's good enough to attract participants with payment of coins that are traded. not many projects are brave and can do marketing like that.
