When that something is volatile, engineered to be so, you don't have a viable exchange currency. Duh.

Bitcoin is not volatile, the current human valuation of it is.
1 BTC is always 1 BTC.
How we value it - that changes, and valuing it with a manipulatable currency system is what's creating the noise.
You'll realize it's a standard, tied to energy/physics unit of account - and is the most stable a money can be.
