I read the white paper (if you can call it that) for another DAG coin which shall remain nameless, but it appears to me to be a "centralized" coin since it will be relying on "reputable" witnesses. Does this one have anything like that?
http://www.tangleblog.com/2017/01/03/byteball-vs-iota-token/IOTA and the other DAG that you read about essentially only share one commonality: they both use a DAG protocol. The similarities pretty much end there. That's not to comment on the utility of each.
