ok then, most of you would go the GPU route i guess
what GPU's would you use?
if i could use the GPU mining, if the price were lower, i would recommend use the AMD pro duo, it has more FLOPS per watt. other than that, i would depend how fast of floating point they are. like GTX1080Ti are mainly for gaming, not mining. i would decrease the clock and have more cores if it could majorly decrease the electricity per core.
yeah i concur, the bitcoin network is as secured as it get, no place for casual mining all is in big farm now
The only reason big farms are profitable because they have profitable conditions. You could equally have a small amount of miners, or just one, in good conditions and it would still be profitable.
For example, you live in a place with low electricity costs, you buy an Antminer or Avalon miner and put it in your basement/garage, then boom you're mining and it's profitable. Often it'll still be more profitable than most investments which we forget tend to actually only get ~10-20% per year for people, and this is riskier but it's not so risky that it makes it unreasonable. Cooling systems etc don't necessarily need to be very good or even in place at all unless you're already doing a big operation.
+1 such as the people who use their heating (if any) as a source of electricity. mining farms would often lead you to be far more busy upon maintaining and/or upgrading the software/hardware; despite it could be more profitable than operating a trading company.
