I mine currenctly XMR (not so great) but bether then ETN. XMR has some value. ETN only dropped in value.
There are much better alternatives for CPU-mining.
I'd recommend checking for coins using the Argon2d-algorithm like Credits (CRDS), Dynamic (DYN) or Nimiq (NIM). According to my experience I'd say Nimiq is the most profitable "CPU-only coin" currently (just make sure to use the external miner and not the browser-mining).
