Regardless of whether or not you think it's overhyped, it's a really really cool experiment in economics and cryptography.
I mean you have the combination of an open source community, libertarians, and a shitload of money. The outcome is pretty obvious.
Very debatable and yet to be proven in any real way. Lots of things have "potential" but bitcoin seems to consistently fail at actually doing anything. Doubtful it will ever solve any problems outside its current scope of use.
For security "nerds", which hn is full of, it's a veritable holy grail of technological security.
Stands to reason that the majority of issues Bitcoin has appears to be human, not technological. Since the technology works so well, bad actors appear to be targeting human vectors of attack- create controversy where there is none, drive wedges between key players, sow dissent among community (a day doesn't go by that r/bitcoin doesn't complain about vote manipulation).
Bitcoin's biggest security threat lies in it's governance, especially if there are subversive elements in its community. BTC leadership has to get their house in order.
