I think Bitcoin is fundamentally flawed and it will ultimately collapse. CMV

I have a limited understanding of finance so I could be entirely wrong here.

But I feel like Bitcoin the commodity and Bitcoin the currency create a problem for eachother. As Bitcoin becomes accepted by retailers its value has shot up immensely. But this volatility ultimately makes it more difficult to use as a currency, because the value of bitcoin paid for something today could be much higher in another year or so. So this makes retailers wary of it, perhaps even causing some of them to drop it, which will make the value plummet, give it more of a reputation for being volatile, and cause a snowballing collapse of the currency.

I think bitcoin will ultimately collapse, but not for the reasons you give.

Retailers accepting bitcoin has some effect on it's value, but the much larger effect is the speculation that is driving it's value up. 

People are buying bitcoin, for the most part, because they think that the value is going to go up, and they want to get in cheap, not because they want to buy things with bitcoin. 

That's the chief reason that it makes a bad currency; the fact that few people are actually using it as a currency.
