Wow an old timer, I see you joined back in early 2012. Back then BTC was $5 a coin. Yes you heard that right guys, $5 a coin.
However lots have changed in the mining world. Basically gone are the days of mining with your laptop and earning 0.10 BTC/day with your i3 processors. You need top of the line processors these days to barely make anything.
People got GPUs , ASICs, FGPA and they are barely beating their power bill. Give you an example, with an Rx 470 8GB, the most common GPU on the market, with an average power cost of $0.10/kwh you make $0/day. The $0.36 profits all goes towards electricity. With CPUs its similar result, same with ASICs.
Werd...
I shut down my A9 Zmasters for a bit until ZEC breaks $50/per coin as the electric bills got onerous, and I have .07 p/kwh in my location. Right now I would be profiting .90 per rig per day. When I first got the A9's I was at $50-$60 a day per rig and was sooooo happy. I'll never see those numbers again but I'll take what I can get.
