The best USB miner is the compac. But USB minerss are mainly for learning or lotto mining, you will not make ROI in most cases.
This is true but you can make your USB mining RIG run for less money if you I wise. I use an old Ultraportable HP mini 210 with a 7inch screen. It has a small PSU of ~30w (laptop PSUs are usually anything from 45w to 65w). I pulled the hard drive out (so no HDD spinning around anymore which can save 10watts) and put Windows 7 starter on a 15GB USB Thumb drive. The whole OS is less than 10GB in size. I use this to run my stick miners and a U3 for lotto mining. Set it up so to not shut down when you close the lid and run it shut to kill the screen (just open it now and again to see it's good). The 30w PSU never even gets warm. I have an old pentium 4 style ATX where the 12v runs the U3 and the 5v runs me a HUB with a couple of Bifury twin chips in it. I get ~70gh for around less than 70watts at he wall all in (inc. mini laptop with lid shut). Some people use linux on a USB as their OS for the same reason. I couldn't get my head round linux even though i made me a USB drive with it on as there is a good readme file in cgminer-9.4.2-windows all about how to do it if you fancy a go. Its called "linux-usb-cgminer.txt" worth a read. It would be interesting to know how others have got on with it all. There are guides to setting up USB miners on linux. Also A raspberry pi will cost you like $30, a decent hub would be somewhere in the $20-$30 range. I am not sure if a pi zero for $5 could do the same work, but it could be possible. Overall at like 20-30W depending on your setup. |

 Had approx 900TH for 18 hours and best I saw was .. 8656858836.6964016 Looks like > 1 PHs is the min now, for at least 2 days .. outta my price-risk-range - but I wonder if using port 3334 messed me in any way. The Germans, with not that much more hash than I had have 655117758757 .. 2 whole digits more .. sux Ports shouldn't have given any problems. But nowadays it makes more sense to get in with a group to reduce your risk. Unless you can risk 10 BTC and not mind losing it. Aye .. learned my lesson. We should all get together (25 people), on an ongoing basis. Each person puts in 0.5 every week, for a total of 12.5 BTC .. get 2.5 PHs for 20 hours. If we hit everyone doubles up. Or 0.25 x 25 for a total of 6.25 = 1PH for 24 hours .. call it CKDay .. limited risk, for a potential quadruple-up. Maybe CK can do the escrow for us.  ezeminer already has a mining group just like that going, we had our first 24hr run completed yesterday with 150TH and got a 7B share, not the 144B that's currently needed, you should join in  I mean it isn't much. I have it at 0.05 per person for a buy-in, but hopefully the group can gain more blocks, popularity and investors to have people interested in the larger rentals  If you're interested: https://bitcointalk.org/index.php?topic=1345538.0 |

You have been added. Best of luck to everyone participating |

Nice keychain! But on first impression it looks like "superman" rather than bitcoin. Maybe consider to change the color theme?to (Orange-yellow...etc)? Either way, I want one  Maybe Orange-White like the bitcoincore logo. Orange Background, White BTC |

Added both of you guys, also added a start time for February 23rd (in case 10 people don't fill spots fast enough). It looks like that will be a couple days after the difficulty adjustment. For the most part rig prices look to be higher around the difficulty adjustments. |

Ezeminer are you starting a new run
I will be. I reset the list. I'm in, same deposit address or are you changing it for the second run? Same address. Also updated to have a changelog for my changes and resets. |

So the rental is over. Our bestshare: 7,144,260,711 Just multiply by 20 and we are good |

I fired up my S1 threw it at the pool, although I gotta disconnect it in the morning, the hotel doesn't allow it, calls it a fire hazard  Well if the miner does hit a block, it would be on fire. It couldn't comprehend that it beat astronomical odds  Also an Update, we have 5 hours left.  |

What happened to the rental ? Hashrate has dropped down to 50TH... was it a disconnection from the stratum server ? Maybe try using port 3334 for the US Server, also are they DE Rigs or US Rigs ?
How long is left as well ?
The rental was beat out in price for a little bit of time, thus decreasing the hash for a little. I'm renting on the westhash side to mine at ck's solo pool. Roughly 6 to 7 hours is left on rentals, I'll have to check when I get home. |

Hey ezeminer nice job throwing this together. I was wondering if you might consider opening smaller pools? I know that alot of ppl get weekly signature payments(i know because i employ them ) but those guys may be interested in say a 20 person pool at .025 per person. Just an idea of course but you may find a few guys It could be an idea for the future, it is just that 0.5 BTC on rentals realistically gets you roughly 2% chance of getting a block. The more people that join, the harder it gets to manage. But i will consider it. |

Can you explain me how will it work? I mean suppose I am investing 0.05 BTC here. So what are the chances of getting ROI and in how many days will it reach ROI? And what percentage of shares will be distributed to each investor after a block is solved? Also how about using that address 1FuL4PkG4MWGEh6JzUzu25CK67LVMyPbYX externally as worker by me on ck pool with my miners? What will be the subsidy then? This is more gambling, but it requires people to invest to pool money together to rent mining rigs. We then point the mining rigs at http://solo.ckpool.org/So say 10 people invest 0.05 each, we rent some rigs and find a block. The block will be divided equally among each person that has a share. If we get a block, then you ROI. If we do not get a block there is no return. This is like buying a lottery ticket, you may win, and you may not win. Edit: Updated the OP, trying to work on creating a cleaner format for users. |

Our order is looking good currently, luckily the bigger orders have calmed down. We have 0.355 left, hopefully we can do it  |
|
|

Bitcoin Network difficulty has gone up from 120G to 144G, Hopefully our group gets very, very, very lucky.
indeed Reason why I held over the start time a bit, we would be paying .0045 instead of .0038 |

You guys see the huge spike on Bitcoinwisdom?
Also looks like we finished again at +21%, probably 50% of the day was on the old diff however.
It has been hovering at 20-21% all day, so this might be another scary adjustment. I don't see under 10% happening this change. Miners are biting a bullet right now, and it isn't getting any easier  |

Yes. People are buying at 0.0039 and 0.0040, I'm just waiting it out a little because there are two orders above us for a combined 2.6ph. If the group wants to bump up the price it is possible, just slightly less mining time. If prices go down then I could drop the price a little to try and get more mining time. Cool, I understand thanks for the update. No problem. Looking at the numbers, if you add 0.0001 to the prices, you lose about a half hour with our funds and our current hashrate. |

So what are the approximate chances of finding a block if I mine solo? Depends on hashrate and duration of mining. But it also depends on current difficulty. |
