So much for the halfing raising price. Small miners quitting. Hate to see the next one.
Price was under $300 in January. I'd say the halving raised the price significantly.
Unless there was some other news that doubled the price in the past 7 months?
No, you're right, the price rise was due to the halvening pump. Now price is coming back down, as always.

Price was $635 at halving. Price now is $655. That is the opposite of down.
Right. And $680 a few minutes before the halvening, but why quibble? Dropping hashrate is dropping, as the fees escalate. As prophesied

The price was $660 most of the day then dropped 3 blocks before the halving.
Of course, the long year trend showed that the price would be $660 the day of the halving (as predicted over 2 years ago).
The formula would be close to this:
P = 13.5t + 12
where t = months since November 2012
Before the halving the rate was closer to:
P = .3t + 1
t being months from February 2010
With the formula after the next halving:
P = 20.25t + 660
t being months from July 2016
Price should be bouncing around $680 mid August (though more likely it will be pulled into the $666 hole until there's big enough breakout).
