Teething problems, nothing more.
I expect this roller-coaster ride on value to continue for a couple more years. Except for those of us here, the whole concept of an electronic currency is a frightening, new, futuristic concept. That means that governments will continue to struggle with it for some time.
Expect changes in the IRS decisions and evolution of how all states address the topic.
As for predictions, $200-300 is my guess.
To ride this coaster, you've got to have a 5-10 year outlook. Eventually, prices will stabilize and BTC will evolve from what is now clearly a "commodity" into the currency it was intended to be.
. . . Then again, I could be full of BS.
