Hello !
What it is wrong with your graph?
You have predicted for the July 2014, a Bitcoin price of $4,900 or at least $1,000 ..
Here we are now in July, and in fact the BTC price still bouncing around the $600
July is not over yet.
You ain't seen nothing yet.
Bbbbbaby you just ain't seen nothing yet!
At this price of $600, you can't do to much with a BTC. Even if you purchase an ASIC, you will never get ROI..
IMHO ~ $600 it is not a good price for the top coin of this world.
Why would you buy a mining machine - buy more bitcoin instead. You will get more coins for your fiat buying at market, and get a better return if the price goes up.
That graph above is not fact, its a prediction based on prior patterns , predictions don't have to be right, patterns do not have to repeat. Have some patience.
