To linearize things (make them 'straight' for analysis) that have points below and above 1, you add 1 to your log (i.e. log x+1).

No you dont!

You might have accidentally done log(x+1)
because log(x) +1 would not matter, it would only shift the entire graph up on the y axis while your log(x+1) totally distorts it.

not when it's logged. try it with numbers above and below 1.

I'm afraid I'm seeing prof7bit's side of things here.

Don't take my word for it, go grab your GCSE (or whatever) maths book.

y=exp(x)

x=log(y)

Yes, you should grab yourselfs a maths book and read it before you start posting nonsense plots of made up nonsense series agan. Good idea. Do it.

and then sell your bitcoins.

Produce a chart to show us. then sell all your bitcoins....
I have posted one. There are even more at bitcoincharts.com and many other places. All of them plot prices as they are and dont add arbitrary dollar amounts to the price before plotting them.

edit: just realised I misread you - Log (x+1) is what I did, log (x+1) was what I meant to do.
Why?

It linearizes it like I said, which is one of the main reasons for logging charts.

It noes not "linearize" it, it distorts it until it fits what you want to see.

Reality (this is what happened):
(a) The price increased 900% from 0.01 to 0.1
(b) The price increased 900% from 10 to 100

if you add your 1 to distort price movements then it would seem like it
(a) increased 10% from 1.01 to 1.10
(b) increased 900% from 11 to 101

So the gains during early period (a) are played down heavily while the gains at later period (b) remain as big as they were. This is neither a linear chart nor a log chart, its something completely meaningless (adding this $1 to all prices does not model any underlying concept or effect from reality, the $1 does not make any sense at all!) You applying dirty tricks to distort reality, to bend the curve until it matches your line, there is no reason to add the arbitrary amount of $1 to all prices before logging, you are manipulating other people with your made-up nonsense charts!

edit: can I take that back, I don't want to see your chart.

You might have accidentally done log(x+1)
because log(x) +1 would not matter, it would only shift the entire graph up on the y axis while your log(x+1) totally distorts it.

You could produce even more funny meaningless curves by using log(x+42) or log(x+23) or whatever arbitrary constant you add to the price before logging.

Actually, you could, and it still wouldn't make a difference when you reverse the transformation for prediction.

By the way, best not to keep editing posts when things have moved on.

No. Add parenthesis just to be sure. Your graph is wrong, the one at bitcoincharts is correct.

oh boy


yeah, it's not linear. You'd have to fit a curve to that, which would predict the price would be about...ooooohhhh, say... 30ish.

Have to agree with sarc on this one. Whether you use log n or log (n+1) for graphing, as long as you use it consistently it won't matter for the purpose this graph is used for: drawing a straight line to represent an exponential growth function. Depending on the log value you chose, that line (of best fit) will rise more or less sharply, but the actual *function* it depicts stays the same, since the line (of best fit) is based on the data plotted on the same log value.

Hey guys
Would you mind 'snipping' your posts ... no problem with chit chat - as you say, there is nothing going on, but my scroll finger is getting tired  Tongue
Glad you settled you differences  Smiley

EDIT: I see a new dispute has arisen ... have fun   Grin

Yes, sorry, completely forgot about that :/

why do I feel like that will be your conclusion whatever I say? What does bitcoinchart predict?

I have to say that after the April, 10th crash I placed big bids around $30. Without much analysis, I strongly believed that the post-crash bottom was going to be around $30, which is the 2011 bubble top.

For that to happen I was expecting a 2011 situation in terms of negative news coverage, "this is a ponzi" screaming, etc.

After we rebounded at $50 with two consecutives all time highs in terms of daily volume, I changed my mind. I realized there are many differences compared to 2011. After the last bubble, people thought Bitcoin was dead. News coverage was extremely negative. There were posts on these forums saying Bitcoin was a huge ponzi, with Satoshi as its very own Maddoff.

Things are very different now. I really believe we won't go below $50 unless there are some very bad news. Thus, even if $25-$30 coins didn't seem crazy to me after April, 10th, I now believe it's only a wet dream of those willing to increase their BTC stash - regardless of what TA says.
