what happens if all bitcoins are mined

[tredel]

If you look at it from a currency standpoint bitcoin is thriving. Currencies took years and decades to develop and become viable options to bartering, and bitcoin has dominated the globe, and still continues to grow.  If it will last, however, we can only see through speculation and retrospect in the future.

The biggest dangers to BitCoin is someone finds something specific to the protocol, hacks BTC Guild (or something similar) that lets them seriously(but subtly) mess with it and it isn't really discovered until too late.
