I am using easyhash. I dont have a huge miner, but it is definately still more profitable right now than my ETH mining due to the still low difficulty. I was pulling about 70 a month profit from ETH mining, and now I am sitting at 200 a month mining Electroneum.
But Like I said I am long on this, so the profit in my opinion can be much higher than it currently is.
When I pulled the large amount out I had about 5% of the total network hashrate purchased. Was super low difficulty, and super low hashrate. So I pulled out good. Only regret is not dumping more in there. I had 3k usd liquid at the time, but again being too conservative. And now that money is spent elsewhere.
I did not try solo mining, but I know some people solo mining at midnight the night before pulled some full blocks while it was super easy. Those guys made some good money.
