Wow, no one here knows what socialism is at all.  To answer the OP post, bitcoin is a free market based mechanism for exchanging value and is in essense the very opposite of socialism since it eschews state controls and socialism can only be achieved through the state.  Marx was not a socialist but if he were around he would probably describe bitcoin as a progressive petite bourgiouse subversion of global capitalism due to its universal and international acceptance but ultimitaly a distraction to workers struggle for liberation from capital.  But the main benefit of bitcoins is that it makes ideology irrelevant.  But in the market place of ideas socialism and communism failed to achieve its goals (at a massive cost in lives, over 100 million) and has been fundamentally rejected by all human societies even where Communism is at the helm for the simple reason that it goes against human nature and no statist project that goes against human nature will last for long.
