Topic: History of difficulty? (Read 4059 times)
If you want to be perfect in this field, then you have to try charts. It is helpful in increasing the knowledge about your related field.
It's basically linear until June, then exponential, a straight line on a log chart, thereafter. As long as the number and quality of fabs cranking out ASICs keeps going up, it stays exponential. When that tops out (in late November, at my guess) the increase becomes linear again, or approximately so -- some factors of maturing delivery channels may offer compounding growth for a while, but at a low rate. The interesting question, then, becomes: What will the slope and intercept of that line be? I have no data to estimate KnC or HashFast delivery volumes in Q4. I do have a Cointerra January order numbered #888, which puts that unit roughly in the middle of the 3rd petahash delivered by Cointerra. If KnC and HashFast deliver at a similar rate, scaled by their chip speeds, I'm thinking in terms of a difficulty around 1,200mm in January.

Damn, I was really looking forward to mining.
It always can get more worse...
13-07-2010 93.11%
16-07-2010 300.04%
Or sometimes it can get better...
15-08-2011 -4.40%
30-08-2011 -1.55%
13-09-2011 -1.26%
27-09-2011 -3.76%
14-10-2011 -13.09%
31-10-2011 -18.03%
14-11-2011 -0.91%
29-11-2011 -8.54%
You'll never now...
It still doesn't stop me from mining!
Good stuff Steven, thank you!

It was actually just a bit worse in April -- but certainly now near the lowest levels seen.

I think mining is dead meat:

Those charts are awesome!

No need to worry, this next increase looks to only be 1.5 million from the current 1.3 million. Yeah, it's bad, but not a another double... thank goodness.
Thank You!

The dates are my rough calculations from eyeballing the graph:

The percentages are increases in dificulty from the previous difficulty number.

try here for a chart
http://bitcoin.sipa.be/
or this query on the block explorer site will give you the raw data (you can save it as a .csv and then open in a spreadsheet app)

I have searched this site and the web in general for some numerical history of difficulty to no avail.
I have a small test rig that over the course of a week has generated 50% less BTC/day at the end of the first week.
Does that mean that difficulty is increasing by a factor of 2 everry week? If so I have no interest in mining gear.
According to my rough calculations anything over 5%/week increase in difficulty makes mining unprofitable.
Does anyone know where I can find numerical values for difficulty increases over the last 3-6 months? Or a chart?
Thanks!
