I recognise Bitcoin as a step to decentralisation in general. BTC as a phenomenon means that demand for an unregulated and anonymous (well, bitcoin is not totally anonymous, still) currency is huge and sooner or later we'll see that countries' borders mean nothing.
That step to decentralization is one step that has truly changed everything and even though it may be pseudo anonymous, which still does not change the fact that it really is disrupting a whole lot of things for the better. So far so good, it is obvious that the fact that we can do a borderless transaction without a third party is one of the things that is making so many real believers of bitcoin to get into this train except for just some few greedy people who want to make quick bucks overnight.
