is it only me or does the whole system of bitcoin mining favor those that have the ressources to buy alot of hash-power? the harder mining gets, the more miners are being sidelined because their mining efforts are not paying off anymore, leaving only the people that have invested massive amounts for multi-g-hasrates.. isnt that sorta like buildung a monopoly or a classic case of the rich become richer?
The main factor is whether or not "economies of scale" apply. Although I have not seen any hard evidence, I think it is probably a smaller factor, since a single mining rig is cheap in my country and mining pools are common. Plus, small-time miners have more frequent access to free electricity.
