Gold hasn't changed much either, but it still has value. I'm a strong believer that bitcoin's value is based on the community that surrounds it, and as long as we promote it and use it for honest purposes, bitcoin's value will rise.

It's a good thing that Bitcoin doesn't change if it's secure. But even if there were a major security flaw found in Bitcoin, the miners could vote to update the protocol. (Someone correct me if I'm wrong, that's just what I'm putting together)
