I try not to have "beliefs" in regards to Bitcoin but more "hopes" and "worries", given that all things could change and it becomes a human nature / society reaction problem more than technical. And putting beliefs in humans as a whole will always let you down and is unpredictable.

That said, the thing I try to fight to avoid the most is government clamp downs and control. The "and then they fight you" threat is absolutely real.

I guess if there's one "belief" I have is that I do not believe Bitcoin fixes everything.
