There are some CPU and GPU which is profitable but your electricity need to be dirt cheap...
Dirt cheap as in free. CPU and GPU mining is for the nostalgic or college kids that have the university paying for electricity. The mining industry has matured beyond CPUs and GPU.
I'm afraid you're right - its kind of scary isn't it? Wasn't one of the key concepts of all crytpo-currency that everyone 'owns' it and was able to mine it? That way there are 'millions' of peers rather then a few big 'monopolies' that 'controlling' the currency. Everyday it seems like there are fewer and fewer (bitcoin) miners and most other currencies are following suit... Is a crypto-world safe with only a few dozen 'big' miners? I've been pondering it for quite awhile...
The decentralisation was one of the main objectives of crypto coins.
But now its already centralised, in some months it will become a completely centralised one.
But it will remain decentralize for algo that is anti-asic. Hopefully darkcoin would have asic so quick...
X11 doesn't have ASIC soon but FPGA already raped X11 to the finest.
Can you link me to those FPGA thread handling X11?
