But what do the green lines represent? Sorry, I'm a bit clueless at finance.
The Green Lines are representing the Highs and lows of the BTC value. It HAS NOT gone outside of those lines, and the lines remain a shallow angle.
Ah, okay. I think I understand.
And the jagged orange line?
That's the difficulty, which will most likely drop again. (going on 3 in a row)
Ah, gotcha.
And the lavender one?
That is the actual price per BTC at MtGox, not to be confused with the high and low
Sorry, I'm confused again: can you explain the orange line?

LoL.
Also, fuck Bitcoin, let it die, or help it along. Bitcoin needs to die to give a crypto-currency that isn't designed like total shit to arrive and gain a market.
Bitcoin was a great proof-of-concept. It served it's purpose, not let it pass and the next evolution to arrive.
