Can I get your latest theory on how China caused this price rise please?

Hard to tell...

The rise from 200 to 250 over the last 10 days may have been just a recovery from the crash of 2015-01-13 (like the recovery after the 2014-10-04 crash). The rise today seems to be due to the Coinbase news, apparently led by Bitfinex.

So far the price got back to the trend it followed for most of Nov-Dec 2014. Let's see what it will do next.

By the way, I still don't know what caused the mini-bubble that started on 2014-05-20. It may have been driven by the West, for all I know. But that demand may have evaporated between August and October.

All money from that sales was take out of exchange? I don't think so Wink

make you a deal, expand as a summation series and give me a closed form expression for the 3rd term (coefficient for x^3) and I'll reveal all ...

It can be written as

f(x) = A \prod_{m=1}^\oo (1 - \frac{4z^2}{(4m-1)^2})

where z = x/\pi - 1/2, and

A = \prod_{m=1}^\oo \frac{(4m-1)^2}{4m(4m-2)}

That is an even function of z. Therefore, the the coefficient of (x-\pi/2)^3 in the Taylor series around \pi/2 is zero.

Is that close enough? Grin

Jorge: thanks for this, it really is an interesting approach. It shifts the curve by pi/2, and normalises (by A) creating a normalised even function.

You might be interested to know the following:

A = f(pi/2) = ([Gamma(1/4)]^2)/(2.pi.sqrt(pi)) = [3.3.7.7.11.11.15.15.....]/[2.4.6.8.10.12.14.16] ; where Gamma() is the gamma function

and

f(-pi/2) = (4.sqrt(pi))/([Gamma(1/4)]^2) = [1.5.5.9.9.13.13.....]/[2.4.6.8.10.12.14.....]

and

f(pi/2).f(-pi/2) = [1.3.3.5.5.7.7.9.9.11.11.15.15....]/[2.2.4.4.6.6.8.8.10.10.12.12.14.14.16....] = 2/pi

Apparently a lot of people are thinking that next week will be very bullish and want to front-run.

China has been an anchor chain on Finex and Stamp throughout the rally.
