Has anyone elese noticed the estimated reward for the current round is dropping like your mining has stopped? Estimated reward is now down to 0.00004556 BTC

Normally I get 0.00030000 BTC or somewhere in that region. the last 2 or 3 rounds show a slightly lower reward than normal but I neglected that as natural fluctuation but only just noticed my estimated reward for this round is dropping by the minute the same as it does when I stop mining, yet all my workers still show last hsare as 0 minutes ago and I can't find any problems with their speed etc

Edit - It seems to be going back up now, anyone know why this might have happened?

I run minepeon on my pi and recently got the adafruit control and display board with a little lcd display and a few buttons. I am just wondering if there is anything I can install to get this running straight away as I don't really have any experience with this kind of thing, i'm a windows user really and don't have very much experience with linux to try and get it working myself! any online guides maybe to help me?

not sure how useful my input is to you but here you are anyway:

I am currently trying out the site cex.io which seems pretty good at first glance, much cheaper than buying physical hardware and you can of course re-invest your mined coins back into more GH/s. I only started with it last night with a small amount of bitcoin from my other pool and so far so good, I think i will invest a little more now everything seems to be as described.

I also sell mining contracts on ebay which is going quite well. I'm not one for ripping people off but people seem to buy my contracts for a couple of pounds for just a few hours on my 5GH/s rig. 90% of people who buy it are new to mining and just want to see how it works and the other 10% I think are people who havn't done the maths on whether my services will turn a profit or not but hey ho. I have noticed the price of competitor services on ebay drop like a stone recently though and as soon as someone is cheaper everyone goes to them instead so i am constantly checking the prices of others and lowering my own but still easily making more in contracts than I am from mining my own BTC.

Anyone wanting to get into mining I would say should buy a small amount of BTC and invest it in cloud mining and keep reinvesting the mined coins into more power, that way worst case scenario is you loose your initial investment if everything crashes which should be an affordable amount. Paying out for hardware like I did before doing any calculations which is unlikely to see a ROI anytime soon is for people like me who buy things on a whim

I had the same problem with my redfury when I got that, I got it working by using the program "Zadig" to force it to use the winusb driver as windows automatically assigned a driver from online which was the wrong one and bfgminer wouldnt find it.

perfect, exactly what i needed thankyou!!!

it's a fresh install from sourceforge that I have done (0.2.4.1) which I believe is the current version and comes with an out dated version of bfgminer.... i think

I am been successfully mining for a few weeks now in windows with bfgminer 3.8.1 but am abit of a noob when it comes to any kind of linux. I have a redfury and a nanofury which minepeon doesn't find so I assume i need the latest version of bfgminer?

If so how do i go about updating?

thanks for the advice I will take it on board. I have now completed a transaction for £10 just as a tester and all went smoothly.

I think I will keep hold of them for a little while but I could do with recovering a fraction of my hardware costs so I will aim to mine around 0.5 bitcoin and then decide from there depending on how the market looks at the time

Appologies if this is a repeated post but I have searched and found some info but I am looking for more.

Basically I am a small time miner and just mine as a hobby. I will probably never see a return on my bitfurys unless the price skyrockets but we shall see. I am currently mining about 0.01 bitcoins every couple of days and at current exchange rate only about £20 worth but I am curious as to the best way of exchanging these for sterling.

I have checked out sites such as local bitcoins which doesn't bring anything up in my area even when I try searching the whole of the UK so I guess I'm doing something wrong

I have made an account on bitbargin but to allow me to sell they want to charge me 0.1 BTC which isn't worth it as it will take me a month just to save to pay the fee...

Whenever I google, the site plus500.co.uk comes up but I havn't read anything on forums about people using it.

Anyone else in a similar situation?


EDIT: I have now signed up to localbitcoins and it is much clearer now as I have found they have an integrated wallet etc, is it a completely safe site to use? Any way to get scammed on there?

for any prospective googler having similar problems, it looks like I am having some kind of driver issue. I noticed that if I go into the device manager to the USB section windows had stopped two of my drivers for some reason. I will report back if i get it running stable!

All I am running through the hub is the nanofury, a block erupter and a mini usb fan so I can't see that being over 1.5A?

It's also strange that my nanofury is the only one that has a problem with it and my block erupter runs fine?

thankyou for the reply,

I have a fan cooling the chips and they get warm to touch but by no means hot. I think I may have solved this problem (touch wood) by decreasing to 53 and also the "pencil mod" which i read would help stabilise the frequency (I used to get alot of the frequency drop over 50% detected message). However since then - no issues!

However, as you can see for some reason when using


I get MMQ show up as dead - I dont know what MMQ is, I assume it is my CPU or GPU as I have OpenCL installed on both but don't use either for mining. Whenever I put


into the .bat file (after my password but before -S all) bfgminer just crashes immediately after it trys to open. By crashes, I mean the window pops up and immediately vanishes. I tried going in through the bfgminer menu (M -> + -> select device) but as soon as I set focus to the "MMQ0" in the list bfgminer closes every time. Does anyone know what MMQ could be or how I can stop it showing up?

edit: i spoke too soon i have my fist problem back though it didn't do it for a few hours that time so i will play more with the numbers

Can anyone help me? i'm at my wits end

My nanofury works perfectly through the laptop USB port but when plugged into my usb hub (plugable 4 amp power supply) it runs for 5-10 minutes then just gives this over and over. Normally straight into the laptop I use this and it runs fine with a usb fan on it, i just get the odd frequency drop line popping up.


I have dropped it down to


Through my usb hub and still getting the problems what would cause this?

This is the problem i am getting. I have just tried the pencil mod to see if it helps, but why would it work fine though the laptop then only give the problem when plugged into the hub?

https://scontent-a-lhr.xx.fbcdn.net/hphotos-ash3/1479239_10202154809285512_151581123_n.jpg

could this be some kind of driver issue or something?

when on the usb port it will run no issues at 2.7gh/s but even turning it right down to 2gh/s on the hub doesn't help?

I have a nanofury NF1 and have been running it quite successfully through my laptop for a few weeks. I also have one of the 335MH/s block erupters too so thought i would try them with a USB hub. I have a cheap 10 port powered hub I thought I would try and sure enough the nanofury didn't like this (not ample power supply once the fan and block erupter were added). So I bought a Plugable USB3 7 port hub which has a 4 amp power supply.

It seems to run fine for about 10 minutes through this hub but then does the same as my cheap hub and just starts giving errors. BFGminer just repeatedly flashes something like "NFY-old-buf - giving up after 4 tries" or something like that but I can't remember the exact phrase.

Heat is not an issue as there is a fan blowing over the setup and the ASICS don't even get warm. any suggestions?

Thanks, so my difficulty is 2? Does that sound about right for about 2.9 GH?

Can anyone answer me this?

On BFG miner at the end of each accepted share it says "Diff 11/2" or "Diff 2/2" etc, the second number is always two but the first number changes every time. I guess it is something to do with the difficulty but not sure what?

so what's the difference between the round length and a block? I assumed that the round was just as long as it took to find a block?

ok thanks, any ideas on price and hashing speed of the new usb chips?
