che scheda video possiedi? puo' darsi non supporti CUDA o OPENCL come gia' ti ho detto.

OPEN CL Supporta schede ATI dalla serie 4XXX in su, se hai nvidia mi pare dalla 8800 gt in su. ti da errore hardware se non hai questi requisiti minimi.

Yes and no, oscillators are good when the market trade sideways or not much trendy. When there is a strong trend it can become misleading to trust an oscillator like the RSI.

Honestly i prefer an upside breakout
this is an hourly chart, last 2 days

Why? At some point things have to change:) the old generation is tied to the gold, bitcoins are for us and future generations.

It works well nice job slush, i've noticed that sometime the data feed is lagged but it could be my internet connection.

Sure, maybe try to replicate my results to see if they are the same.

Here it's more clear, weekly chart since the beginning, done with sierrachart. Impressive 3 weeks expansion with more then 500k btc that changed hands.

Maybe long term investors.

I dont know:) probably it's a self referential system with a mutual interaction beetween these 2 aspects (speed and price) ; speed influence prices that then influence network speed and so on trying to find an equilibrium, in the meanwhile they oscillate.

This might help:

I found, playing with statistica 7 by statsoft, a nice relation using instead of difficulty the network speed in terahash/sec to price btc/usd ratio.
The formula is:
btc/usd ratio=-.4621+exp(-.56571+(1.50987)*networkspeed)
where networkspeed it's intended in terahash/sec.
Example; actual speed it's 1.385 (from http://bitcoinwatch.com/)

so

fair price = -.4621+exp(-.56571+(1.50987)*1.385) = 4.13 $/BTC
the tolerance of the exponential fitness it's around +/- 1 btc

EDIT: btc/usd ratio=-.25882+exp(-.80633+(1.65207)*networkspeed) this formula is better and use last 150 days or "bitcoin GPU-era"
if network speed will drop to 1 TH we will have 2.07 $/BTC as fair price.


this is the regression fit chart
observe vs regression

Six consecutive weeks of rising prices, i bet on the bull manipulator:)
Of course a sudden drop in price might incites further selling, after all this market it's thin and pretty hard to predict for now but i'm more bullish then bearish. Consider that sellers can monopolize the trading in a stock for a brief period of time, creating a sudden drop in price but then value buyers will step in once the price falls to a point deemed "too low", and bid the shares back up, i think we are seeing right now lots of long term investors attracted by the bitcoin opportunity and others ready to step in once a fast drop materialize.
I'm not much worried.

Buy 50% now , if it will correct a bit buy the remaining 50% of the 100% amount of usd you wanna invest in btc.

This is my version of the channel

sorry for the average quality but it's still clear. the channel at dec 2011 will range from 5$ to 20$ i drew 3 horizontal lines at 5,10,20$

it's a psu issue, i've had the same problem with my old 500 watt psu, now with an OCZ 900watt 90% efficiency it's all perfect and no more BSOD.

Yes you're right, i'm checking using the last few data points of difficulty increase.
this is what i obtain


around 1,7 mln difficulty for november, 6 months from now. i used the "gpu" historical data.
To match this new value, i've to use 18% instead of 8.6% as "Expected average change in difficulty" in the spreadsheet.

I considered a target price of 20 for jan 2012, with 6% you have it, 20$/BTC for jan it's expected if prices will continue to rise with an exponential growth. The growth isnt linear, i simulated a cycle with 4 weeks of big expansion and 8 weeks with price retracement as we seen in the last months, i think that the most probable target it's 18-20 for jan 2012.

8.6% it's calculated forecasting an exponential increase of difficulty using historical values as a starting point, we will probably hit 1,400,000 difficulty for jan 2012 with this pace.
Indeed 6% for usd/btc weekly growth factor it's a conservative value, if a real boom kick in then 10% isnt impossible thus 70$/btc for jan 2012:) instead of 20.
cheers

with those 2 numbers you will see that it's more profitable to mine and hold. with my 5870 i've a 12 month profit of 27000$ (mining) against 17300$ (investing)
