Topic: Difficulty Increase at 131040 - MASSIVE (Read 9909 times)
It seems I won. My address in the signature.
Exchanged rate says; "JUMP!" Difficulty asks; "How high?"
And the system plans to solve 6 a day?
6/hour. I'd suggest to read some FAQs, wiki and basic info articles. It will help to understand bitcoins basic principles.
And the system plans to solve 6 a day?
But every 2 weeks?
Every 2016 Blocks.
But every 2 weeks?
Do they increase the dificulty every 2 weeks?
it could decrease as well.
Do they increase the dificulty every 2 weeks?
When do they reveal the next Difficulty?
Then i will build up my rig or send everything back
predicted: about 834000 in about 50 hours already. Then i will build up my rig or send everything back

Difficulty increase didn't seem to make as large of an impact as I thought?
Anyway, if you guys are worried about it and need a bit more power, Sapphire HD 5830's are on sale for $109 with free shipping on newegg, or the XFX 5830 is on Tigerdirect for $99 after rebate. Pick em up while you can, as xonar said, they're not in production anymore.

5830's are still plentiful and cheap. very cheap. 4 5830's can get 1.2Gh for $440.
Mining is currently constrained by the supply of ATI cards. Browser mining, FPGA's or ATI increasing manufacturing of older products could change this, but right now I am betting about 600,000 at the most.
As much as I like the FPGA/ASIC idea in theory, you are right, this is all GPU, and that won't change until either the BTC price stabilizes for 12mo, or the capital expense for these techs drops to less an order of magnitude above ATI cards, which does not seem likely. Nobody in their right mind would invest tens of thousands of dollars to build low ROI hardware to play in a market this volatile, especially given that it might become illegal in some large markets in 6mo. With GPUs and ROI around 1000%, not so big a risk.
Does anybody have numbers on the number of ATI HD GPUs actually produced? What would be the hashrate and relative difficulty if every one of them was put into service? I would wager that that number is a hard limit at least until a new line of next generation GPUs comes out.
5xxx cards have been out of production for ages. Sapphire recently released some 5850's and 5830's under the 'Xtreme' brand but those sold out within weeks due to low pricing.
6000-series cards are still out in the open as they "just" came out, but costs are pretty prohibitive compared to mhash/s. 6950 and 6990 are the only viable cards tbh.

my official guess, 736914 
i will still use this number, i think its a good guess
Ah, so it's not directly related to hashing power but rather time to completion. Useful info-mation thank you.
So difficulty and hashing power share a proportional relationship, to double the current difficulty you will need to average double the previous rounds average hashrate. That makes me feel better about mining, unless we see some massive influx of people or some new mining tech comes about shouldn't be seeing 1mil for quite a while yet.

It's calculated as new_difficulty=old_difficulty*(time it should take to create (14*24*60*60/(10*60)) blocks) / (time it really took to create (14*24*60*60/(10*60)) blocks), unless new_difficulty > old_difficulty*4 or < old_difficulty/4.

I guess ~600k next round and ~800k the following one.
