I don't know how many mining companies there are, but if there is only one or two companies that take 80%+ of the market, then yeah, that is a monopoly/duopoly. Online - one company (Google) controls most of search, two companies (Google and Apple) control nearly all of mobile OS, one company (Amazon) more than half of cloud market, one company (Facebook) controls much of social, one company (youtube/google) controls most of video market.... etc etc. |
