You know what I would like to have for a X-mas present a Bitcoin Mining that just use solor power. Than with that I wish that it can mine 0.5 bitcoin a month. That would be a nice gift for me. 500 dollars is also a good gift.
I think if we reach 500 dollars it will go down, better for me because I can buy more.
Well, if a such a technology is release, im guessing that such profit wouldn't last long, because the big miner players would automatically start stacking up on those new machines, raising the difficulty, and leaving the solo miner at the starting point again. Unfortunately i dont see a clear way to decentralize mining.
