Comment Bitcoins weakness (Score 4, Insightful) 351
The problem here is that mining these days requires custom ASICs made to compute the double SHA-256 used by Bitcoin as the proof of work, CPUs and GPUs just don't cut it. ghash.io is the pool attached to the larger manufacturer of them, and as its always more profitable to mine using your ASICs than sell them, you can't just buy a bunch for anywhere near the cost price and mine yourself.
Solving this will require someone to make and sell the mining hardware at near the cost price instead of using it themselves. They may lose a bit of profit but in the long run the network will be better off.
