I'm mining Electroneum with a hashrate of 3.6 kH/s and my estimated profits are around 300 ETN per day. In reality, I receive around 150-180 per day. When I mined Ethereum the estimated profit was pretty close to the one I received, but with Electroneum things look a bit different.
Been using:
Easyhash.io
Hashparty.io
Electromine.fr
All of them were pretty unstable with payouts (using Hashparty.io right now and I have 62 ETN pending from the morning)

.
If I may ask, then how many ETN coins do you mine daily and what pool are you using?
