The recent price increase is nothing compared to the bubble of 2011 or some earlier jumps.

You can clearly see it in a logarithmic chart and even more clearly in this relative momentum chart (green curve):

It was done by setting the price in relation to a long time exponential filter.

(invest reasonably)

there is still allot of room just to beat a recent bubble

the question is Zimbabwe did produce anything except money ?  ;D

I love this chart!

haha bubble talkers are funny they wanna decrease but valu enever decrease for bitcoin :) hold = rich easy concept easy for all people to make money

bitcoin up 1000% 1 year this year 5000% we reach price 1000 $ to the moon!!!!

sure:

Yes, yes. But what does it mean?  :D

So if I read this right you're saying we haven't even started yet.

hehe.

It applies a very simple to implement/calculate long time filter to the price. Filtered data is the orange dotted line in the upper chart. Similar to a "simple moving average", SMA or probably more similar to an "exponential moving average". Data resolution is 17-19 mins so you can calculate the time constant of the filter if you like.
Then it takes the difference between the price and the filtered curve and sets it in relation to the filtered curve.

The idea is to remove the trend and only show short term movement in a normalized way so the situation now can be properly compared to earlier peaks.

the code is quite ugly and part of a larger class (this is some surrounding world to these lines, that also store data)
first part does an "average" between a lot of numbers, like drawing a very smooth line through the data points.
the second part is a bit odd to me, because i don't know with what value "indicatorY" begins. maybe, it subtracts this smoothed value from the chart data and calculates the percentage change (divide + multiplication by 100)

So the diagram states that the price today is not as far off from it's long term average as it was back then? We only saw a 500% increase instead of 3500% given the same time constants?

Yes, its a little hard to understand but compare the top diagram blue line from April-July 2011 and compare that to Jan 2013 onwards.  April-July 2011 shows a much steeper rise.

So bottom line: what's the resulting price projection?

By the looks of it - if we were in a bubble it would be about 600.

I have to admit, made me laugh :)

:D Of course this time everything will be EXACTLY the same as before, only scaled up.   ::)

see quote.
with info here: http://en.wikipedia.org/wiki/Moving_average#Exponential_moving_average
...you can calculate that the filter is similar to an exponential moving average of a factor of 1224 (note that this is quite different from SMA).

This would interest me, too. Just pulled it out of my...

I guess normal stock prices do not fluctuate by such large factors. But with Bitcoin an approach like this seems necessary.

nah it would be around 300. You have to subtract the base value before multiplying.

People are much more afraid of a bubble now than back then, though.

I guess that depends what price they paid for the BTC.

No, it depends on the filter.

we are in rough see now...

Something like this. We've seen 900% growth this year as opposed to 3,800% in the 2011 spike.
