Initially we where doing this only for ourselves. We have since decided to build additional centers as a business.
Our prices include electricity, internet and remote access.
Just to be clear, this is not an idea, we actually are on our second mining center which is almost all sold up as well.
So based on the above reply the 299 dollars include everything , internet access and remote connection through remote desktop or teamviewer and also electricity cost. Right now a computer with 8 graphic cards makes about 12 dollars daily so is about 360 dollars or 60 dollars monthly profit. I believe that you let users 100% control of how they want to get paid, in bitcoin ,ethereum or the altcoin of their choice.
So far so good but I still do not see what is your profit by doing so , that is why I am still skeptical. Honestly I don't believe nowadays someone does this for passion, nowadays I am convinced 100% of the people I know do it for money.
