Many suggest setting your difficulty to your hashrate in GH divided by 1.4.

Follow my link in the previous post for info on earnings and worker difficulty. Average earnings unaffected. Variance affected - read organofcorti's analysis to learn how (you find it if you follow the link above).

Bitcoin difficulty is currently 510,929,738. Lately this keeps going up and reducing your earnings. This site visualizes the countdown until next difficulty adjustment: http://bitcoinclock.com/. It doesn't help to switch to a smaller pool. It doesn't help to switch to a bigger pool. When more mining hardware goes online the difficulty will go up at the next adjustment and then your earnings will drop. This may seem harsh, but this is one of the mechanisms that keeps bitcoins from being spammed the way "Helicopter Ben" is spamming US Dollars right now.

What you are talking about is individual worker difficulty. That is something else. If you get a proof of work at difficulty 8 then that counts the same as 8 proofs of work at difficulty 1. Worker difficulty does not affect your average earnings, but higher worker difficulty does give a little more variance. You can learn more about worker difficulty here: https://bitcointalk.org/index.php?topic=27062.msg3142713#msg3142713

Yes, with higher hashrate you earn more. The document I linked to doesn't say that earnings are even. And whether something is fair largely depends on your point of view.

It's important to note the difference between:

Daily average earnings: what you get per day when averaged over many days
Daily variance: how much your actual daily earnings deviate from the average from day to day due to the lottery-like nature of mining

Your average earnings are affected by your hashrate and the current bitcoin difficulty. That's why a simple bitcoin mining calculator only needs to ask for these two numbers. Take this one for instance: http://www.alloscomp.com/bitcoin/calculator - although it also asks for the BTC/USD exchange rate so it can show earnings in USD. Of course this is a little simplified, it doesn't take into account extra income from transaction fees and merged mining, or expenses like pool fees.

The pool hashrate affects how close your actual earnings will be to the average calculated above. The larger share of the global hashrate that the pool has the more the good and bad luck swings will be evened out. Time of course also evens it out. The longer you mine the more the luck swings disappear into the average.

The pool hashrate affects your variance. Your average earnings are not affected.

Welcome to Bitminter! You decide if you want the use the perks. That's entirely up to you.

Bitminter used to be based on only donations and most miners didn't donate at all. I was basically paying to run the pool. Now you can choose anything between 1% and 3%. And if you pay more than the minimum then you get some perks as a thank you for supporting the pool.


Sorry, manual payouts are still on the TODO list.


There's a delay of 10 shifts from the time you do some work until that work is fully paid. Currently that's taking about 10 hours. So after 24 hours a lot of the work is still not fully paid. There is also variance to consider - some days are better than others. Comparing the luck of two pools isn't really all that useful, because today's luck has zero influence on tomorrow's luck. Since BTC Guild added the same PPLNS we have, just with a different shift size, the reward system should be pretty familiar to you. There's more info here though, if you're interested: https://bitcointalk.org/index.php?topic=27062.msg2769824#msg2769824

Fra skatteetaten:

subseaguru has taken over the lead. An even smaller miner, with just 17 GH/s.

What are the odds?

We need some more hash power.

The Bitminter hashrate is falling behind the BTC/USD exchange rate.

The blocks are just rolling in this morning.

bitmeme's first place was beginning to look secure - that hash had been sitting first for some time. But from out of nowhere comes KPR120, a miner with 30 GH/s hashrate, taking over the lead.

Is it the revenge of the small miners? Can a Butterfly Labs Little Single beat piles of the fastest ASIC devices in the world? Is mining just one big lottery? What's happening!?!?

Strangely my fury device runs perfectly on both my windows 7 and os x maverick machines. Haven't tried on Linux yet.

I'm not sure what the problem is.

Take it easy, this is supposed to be the civilized part of the forum.

Good to have a discussion on hubs. I wish those selling USB mining sticks would inform the buyers better about how to run multiple sticks. I'm getting a ton of support requests. I'm asking some of them to ask their questions here because I have no hands-on experience with the issue myself.

By the way, I can't reply to those who mistype their email address or use an anti-spam service that require me to type in things I don't know. If you didn't get a reply then try again and make sure you avoid those two issues.

I think they are the same, just different color. The one I got is just regular grey metal for the heatsink and green circuit board.

That's very odd. If you hit engine start twice, does it start hashing again? Or do you have to shut down the client and restart it?


Thank you kindly, sir.

Pool hopping seems to be mostly dead now. It was based on switching pool when you could tell in advance that payouts were going to be low in your current pool. It worked very well with pools using the proportional reward model, and somewhat less effectively with Slush's score based model. The point is that you can tell in advance with those reward models when low payouts are coming.

With PPLNS you can't tell in advance what future payouts will be. Trying to pool hop based on payouts from the past does not work. Thinking past luck influences future luck is called gambler's fallacy. It does not work.

Wow, you resurrected a 2 year old thread.

Your hashrate doesn't matter for choosing a pool or reward method.

I would recommend Bitminter. It rocks.

OS X Maverick. I just put the red fury in the USB port and everything just worked.

Apple seems to block Java in Safari by default these days. You can use another browser, try to get Safari to accept Java, or start from the command line. From command line, open a Terminal window and type:



Yeah, that's normal for these devices. Apparently for every job it reports one bad nonce even when it is working OK. I'll see if I can stop counting those in the next beta version. That should make the error count more accurate. It will still be high though.

What if you only have one of the non-working ones plugged in? It's still not working?

Maybe they are not getting enough power. Some laptops don't have good power on USB ports.

Did you try unplugging them, then plugging them back in the USB ports and probing all ports again?

Did you install the bf1.inf ?

On Windows 7 I had to do that. On Mac OS X I didn't install anything, it worked out of the box.

There's a blue fury support thread here: https://bitcointalk.org/index.php?topic=319419.0 with installation instructions.

If you are using Bitminter client on Win 7, you'll need to download the bfgminerwin.zip file and install the bf1.inf from there. You don't need the rest of the files if you're not using bfgminer.
