But it is
extremely unprofitable.e.g. I have been mining XMR on a few dozen cores for a few weeks and I have only made about $20 in total (and don't even get me started on the unprofitability of BTC mining).
You will be paying more for the VPS than the amount you make, so you are essentially mining at a loss.
Pretty much all CPU mining is done at a loss anyway, the best it can do is limit hosting bills by utilizing idle compute power.
I'm guessing your CPU power is a Xeon processor? Why don't you start mining verus and Epic cash instead? These are the two most profitable altcoins to mine on CPU right now, way better than mining Monero
Are you doing it or done already ?
