You will see the real driving force at the end of this story.
End of the story states that...
Pyramid Schemes
So where is money comes from? A latest topic on 8btc may tell the truth:
The thread claims that the MMM are the key forces for driving the price up
So, do u mean, Bitcoin has reached 900 USD because of MMM?
Latest surge in litecoin price where litecoin went up to $8 was because of some pyramid scheme in China, I wouldn't be surprised if something similar is helping bitcoin price right now.
