I like the idea of Bitcoin. It's fantastic.
Not if you actually understand finance and risk it isn't. Bitcoin is an interesting experiment in some ways but as a practical matter for real world use it's rather clumsy, risky and impractical. It's flawed in so many ways I barely know where to begin. The only thing about it that I really think might eventually prove valuable is the block chain technology which has applications far beyond bitcoin.
But in reality it's still trading more like a commodity than a currency.
Currencies ARE commodities. The term commodity is specifically used for an economic good or service when the demand for it has no qualitative differentiation across a market. A dollar is a dollar no matter where you trade it. Don't feel bad, a lot of people fail to understand this. Currencies in forex markets are traded very much like other commodities. They're just an abstract/intangible sort of commodity rather than bars of gold or barrels of oil. There is some nuance to the market just like every other commodity but they really are commodities all the same.
