During the gold rush it wasn't all miners that profited the most. People selling hatches, jeans and brothel owners profited greater.
Same thing when the internet started. It wasn't the online retail stores that profited. It was the web designers, flash animators and coders
What field will blow up as the not so obvious market when bitcoin hits mainstream? Just an interesting thing to ponder as the parallels are so obvious. I for one will educate myself, and probably start mining just to learn about it.
