Most of the users make a combination against the nature, using Bitcoin together with banks and centralized exchanges, having no knowledge about its libertarian and crypto-anarchic grounds.

Two websites are good to get resources and learn about bitcoin. The second website is not built by or own by Satoshi Nakamoto.
