Bitcoin price rose by 25% in a week ,why ?

[twiifm]

Is there any solid (or even pseudo-solid) research about the fundamentals that impact the price of bitcoin?

I am curious from a Finance/Economics perspective about the long-term drivers. I would imagine that in the long term, the cost of energy and the price of bitcoin mining hardware would play a big role.

It would also be interesting to know if there is any correlation between bitcoin price and various global stock indices, currencies, and commodities.

Any thoughts?

Increasing demand and rising mining difficulty resulted in this increment.

assume everyone here answering you does not really know, because anyone who does know why, is banking on it and using it, and the masses NOT knowing, is why it keeps happening, lol

My guess is the recent positive news, such as apple, ebay, etc.
