What's the end goal? Where do you see bitcoin ending up? Replacing current currency? Being an additional currency along side the USD, GBP, JPY, and 20 other digital currencies etc? What is the role of bitcoin in the future?
I believe that most modern countries will adopt a blockchain based currency using the technology of bitcoin, however that will be inflationary and central bank controlled. I don't think you'll see bitcoin replacing current currency, but you never know if there's an application that will make bitcoin something that everyone needs.
To use digital music as a comparison, I feel as though we're in the "mp3 stage" of the development process, sitting in front of your computer listening to digital music. It still isn't very easy to get your hands on bitcoin without a sense of adventure. We still haven't seen the Napster, ITunes or IPod of bitcoin. Bitcoin is still waiting for the applications and devices that make it universal. If and when that happens, who knows the impact it could have?
