all depends on your energy consumption. i mine for free because electricity is included in my rent. very profitable right now. hoping they don't find out.

there are tons of ways to produce cheaper power. i have a friend who uses a mini hydro dam in a river to power and cool his miners. also wind power or solar would be cheaper in the long run if you can get over initial costs. i also cloud mine with 3 different companies. passive income is the way to go in 2018. hope that helps
