Any curve can be represented as a sum of sinusoidal curves, i.e. a Fourier series.

Not quite. Any periodic curve can be represented as a sum of sinusoidal curves. The trick is in knowing the periodicity of $=f(t). protip: that f() ain't periodic.

Nope.
An infinite fourier series can match any continuous differentiable function.

An infinite series of a non-deterministic function is unrealizable.

Unless you know the function a priori, you cannot derive a convolution thereof. If you know the function a priori, there is no need to convolve it in order to profit. The entire concept of obtaining a Fourier series of $=f(t) is therefore nonsensical.

Obviously we don't know what the price curve is going to be in the future. That's not the point. The point is that if the price starts at f(t_0) = X and ends at the same price f(t_1) = X, and in between it has lots of ups and downs, then this method will increase the end-value of your total holdings (expressed in BTC or in $). It doesn't matter what f(t) does in between. You don't have to know ahead of time what f(t) is going to do. The demonstration of this statement makes use of the fact that f(t) = the sum of lots of sine waves, for any f(t). This is true even if we don't know ahead of time what exactly f(t) is.

There is a simple way to do a sanity check to determine if what is proposed is nonsensical.

1) Find a price level X where the curve hits at 2 points, t_0 and t_1. Solve for f(t_0) = X and f(t_1) = X.

2) Find another price level Y where the curve also hits at 2 points, t_2 and t3. Solve for f(t_2) = Y and f(t_3) = Y.

Use the 2 solutions to extrapolate 2 curves into the future. If the curves are wildly different then all this would be a waste of time.

i've been away for months dealing with, you know, life. but i've kept an eye on the price.

seems like a steady climb this time, not any sort of real sudden climb. maybe we'll hold it this time.

[keithers]

It's crazy how that if BTC were any other "traditional" investment, it would be front page news of any news outlet because of its rapid appreciation. I guess we'll need to wait for another hack or some sort of FUD for BTC to be the main headline again

[rjclarke2000]

Looks like under 1000 is coming. What is everyone else seeing over the next few hours?

[K~Ehleyr]

Looks like we're having another little correction before the next flight upwards. Looking good as far as I can see, consolidating as we go along!

[Lauda]

Who is leading this 'dump'? It would be nice to see 1000$ hold.

[rjclarke2000]

Hello 3 digits my old friend....

[HI-TEC99]

Who is leading this 'dump'? It would be nice to see 1000$ hold.

Bearstamp has overtaken bitfinex in volume (according to bitcoinity) now a dump's started. But coinmarketcap contradicts that by showing bitfinex has twice the 24 hour volume of bearstamp.

China can't be leading it because its volume dropped since it went to sleep.

[Ted E. Bare]

LOL Who sold at the bottom? 

[Ted E. Bare]

We know that you are out there.

[petahashminer]

Europe exchanges trying to pull over Chinese huobi and okcoin, but Chinese are simply saying f.ck off.

This is the short brief of last 20 minutes.

[Ted E. Bare]

China too strong.

aug 7th 2016 price $593....dec 19 price $793, a gain of $200 in 131 days, average gain of $1.51 a day over that timespan.

dec 19 2016 price $793....   jan 2nd 2017 price $1030 gain of $237 in 14 days, average gain of  $16.92 a day over that timespan

just sayin....

[rjclarke2000]

There are never any surprises when a correction happens, just a slight bit of disappointment here.

Correction is healthy

[soullyG]

Bullish as fuck right now

[spooderman]

every gesture towards a reversal is failing at the moment.

my only question right now regards how much longer china can remain tolerant of people using bitcoin to get around the capital controls.

the most important factor in this would be how much clout and wealth the people engaging in this have.

bitcoin was designed for the unbanked masses not the chinese middle class (specifically anyway).

of course both are in accordance with the values of the old school bicoiners among us, but it's worth considering i think.

i don't believe 'normal' chinese people are anywhere near bitcoin, just as no 'normal' westerners are either. it's still the province of enthusiasts, visionaries and weirdos regardless of what country they're in.

we'd already be firmly in the tens of thousands if regularish folks had taken it to their hearts. and yeah, the chinese government would squash the exchanges. they have nothing much to gain from bitcoin spreading.

if they're willing to shut down their stock markets then they're sure as shit gonna shut down a few obscure bitcoin exchanges too. i'd prefer if it happened sooner rather than later.
