Bumping as it's still happening so I figure some might need to read this - https://bitcointalk.org/index.php?topic=1214476.0Do not use secret question to reset your account password. I would suggest removing it if you have one. It's a pain and possible waiting time to get account back. |

Be carefull with the U3, it has quite a large "zombie" problem... If you find a way around it, or if you're lucky, the hashrate for the cost is great (especially if your power is free)
Actually it really has a pretty good fix at this point. Buy a R1 with Crazy Guy's custom firmware - https://bitcointalk.org/index.php?topic=612390.0I run 3 U3's that I constantly had to deal with zombies now without hardly any effort. It ran for 5 day's without any issues. I am now testing again to see new number but his custom firmware is amazing programming on fixing zombies. BUt can you actually explain me what the zombie problem is? Its first time i heard about it... JUst for security i canceled it until i get some more info about what that is... Thanks The miner stop's mining goes into a state it does nothing. So like a "zombie" it sit's there and does not mine. It is well known with U3's. The R1 with crazy guy's firmware really is a great fix for me at least. It's ran great with 3 U3's. |

I tried countless combinations and found this to be the best:
--bmsc-voltage 0805 --bmsc-freq 1306
Hashrate: 53-60Gh/s
If you are still using --bmsc in your .bat file then you are using the old Bitmain cgminer fork. You should update to the latest 4.9.2 release, it had some changes made just for the U3. You can d/l it from https://github.com/ckolivas/cgminer, check readme.asic for update U3 commands, --au3-volt and --au3-freq The only settings that my U3 will run with <5% HW error is 785volt and 237.5freq, averages like 42GH/s. I'm still using a R1 with crazy guy's custom firmware. It really is like night/day compared to when I was running it on window's dealing with zombies. I go day's first time was 5 day's without any zombies, and before I had to fix multiple times a day. Now I reset after that 5 day's and are seeing how long I go again. It's a lot nicer not waking up to fixing zombies and fixing before bed every night was my ritual with 3 U3's. |

Yuck, that price on an S3+ is horrible. Since you are starting out mining. If you decide to do it, I will sell you a S3+ much cheaper.
Lower prices for hardware always help you get to ROI faster. Use the ROI calculator notlist3d posted and see what is a price you are comfortable paying.
The thing is with BTC going up in price, gear follows. S3's I expect to go up compared to what they were during the BTC at 230 day's. And there is no guarantee BTC will remain high (I hope it keeps going). So good for all of us holding gear, bad for purchasing new gear. Just keep all that in mind when you are purchasing gear. |

200W solar panel = 1x0.8 meters. You need a lot of area to power a few miners, just saying!  Solar are generally a great investment tho, especially if you can sell the excess power back to the grid. It takes about 15 years to ROI a solar install, depending on size, they last about 25 years. Gives you 10 years of passive income/free power, where you can re-invest in more solar! #TheDream That is the thing is it's a LONG term investment on solar. Bitcoin miners are more short term to a point at least compared to solar. And the thing is whall you wait those long years for the solar to ROI you will be behind the ones with cheap electricity. You really just cannot compete against the cheap eletricity. They will ROI many times over whall you are still working on solar to ROI. It just does not work out as much as I wish solar did. |

It all depends with free you have a very good start. I would suggest doing a little research first before jumping in. But also here is where you can calculate ROI - https://bitcoinwisdom.com/bitcoin/calculator . Keep in mind difficulty will effect it over time, you can speculate it, but there is no way to know it for good. |

Bitwisdom:
Bitcoin Difficulty: 62,253,982,450
Estimated Next Difficulty: 64,955,558,706 (+4.34%)
Adjust time: After 257 Blocks, About 1.7 days
Hashrate(?): 458,396,432 GH/s
Coinbase: 378.99
I still think it will be interesting on how much it goes up as Avalons ship out.

Something interesting to ordering if they give everyone the same quote it looks like 50 is the magic number: https://bitcointalk.org/index.php?topic=1171705.msg12931603#msg12931603Unit Cost:
For a group buy of moderate size they can do $1350/unit, raspberry pis included. We may get a small additional discount if we get a buttload of them (50+).
Shipping Cost:
If we get less than 50 units it will cost $50/unit (via UPS, ew),
If we get over 50 units they can ship via air freight. That's ~$20 a unit, and can get lower if we buy more. If we got 100 units (I know, it's a big ask), I've been told it goes down to $10 per unit.

Gridseed has been TOTALLY UNPROFITABLE as a SHA256 miner for a long time now. They were close to that point when first released.
They can be profitable if you have fairly low electric cost as a Litecoin (Scrypt) miner, but they're getting marginal even there unless your electric is well under 8 cents/KWH or so.
The "blades" never were designed for SHA256 mining, they don't have the power capability OR the cooling and WILL FRY FAST if you try.
The "orbs" were designed to dual-mine but the power circuitry was marginal for that.
The "Compaq" stick does not have a European maker but they do have a European reseller.
Are you sure on this? I'm pretty sure it's made in Europe or at least assembled there.- https://bitcointalk.org/index.php?topic=1141518.0The site from thread that sales them is - https://www.bitshopper.de/ they also have a amazon but amazon is higher priced since amazon fees. It's a completely different design for Europe and includes free shipping to some of it and vat included. So price is higher then US version but it is good it's available if your in Europe. Thanks! I am now thinking about buying or the Usb that reaches 23gh/s (8 without overcloking) or the miner that gives a hashrate of 63 gh/s. I donīt pay for electricity and as they cost the same the choice would be clear but; I have read that it sounds at 25 db (dont know how much that is but will try to investigate); for my reasons, i can only have that at my room, and... i like sleeping XD. While an Usb i guess that would do no sound np? THanks for your reply Indeed, a compac stick is soundless. But the PC where you plug in the stick might make a sound Yap, i will plug it into my laptop, which is soundless. Even better is a raspberryPI. If you end up running it 24x7 you will really like the low electricity use of the RPI vs a laptop. It's a little bit more upfront cost but will save you overtime. I highly suggest getting one. |

there are so many threads like this. better u go check first before u posting  best way to earn here is by signature campaign, trading, and gambling. My apologies for making another thread. I'll do my best not to make a duplicate thread again. I'll do a search before I create a thread. With that out of the way, signature campaign! I'm in the same one as yours!  777coin seems really good, so yeah. Trading: I'll try that and see if I can get some more coins to play with:) Gambling: Yes, yes, yes. Gambling is fun, I'll have to say. 777coin makes it fun too :p Anyways, thanks for the advice! I don't recommend gambling. They're got house edge so you will eventually lose, no matter what. Just gamble what are you willing to lose  Gambling can be a good idea for you only if you are really good at it. But if you aren't why not simply provide a service (S/W development, etc.) to earn your BTCs? seems like a good and legit idea to me. I would go for providing service as a way to earn BTCs myself. I don't know if you can consider gambling to be a good idea. Most of the gambling sites are pretty unregulated. And I think the most common is dice. Dice is a game of chance. There are systems... yes. But ultimately your fate is random. And it is pointed twords the house winning. Do not take your hard earned money an gamble it and consider it an investment. If you do it know your doing it for fun. |

All depends on the underclock which I'm hoping we will see anyday. If the Avalon 6 has the underclock like 4.1 you will want these to be able to underclock. But if it's underclock is not like 4.1 then it's not as big of deal. So we should see pretty soon hopefully on underclock. |

I doubt that a V4 contract will achieve 9% ROI - my calcs come in at less than 7%, with some significant potential they won't pay off fully due to the halfing rendering their nominal S7 unprofitable before they pay off in full.
Still compare this to any banking account it is a lot more interest then I ever get in my standard savings account. But granted you don't get if in US FDIC insured and all that. It would be nice if they bump it back to V3 values. But seems like that is a unlikely thing to happen. |

You will need some serious investment that too with free electricity to gain something very high in % on your investments with mining, as next year halving will be taking place, and so rewards will halve though, so making BTC will be much harder than it currently is...
It totally depends mostly upon what price Bitcoin will possess during halving and ahead months...
It does not necessarly take free electricity. But it does take fairly priced electricity. With 230 priced btc many of us were doing ok at mining as long as we use current gear. Jump up to 380ish.... and were doing a whole lot better. Granted it always could change that is the nature of BTC. But I do not see free as necessary, just a really big bonus. |

Looks like BW.com is not putting any more Hash for sale on the 10PH B-Eleven and is in countdown to open B-12 with a further 5PH at 0.5BTC/TH https://www.bw.com/twelveHowever no further updates on the progress on the B-Eleven Miner? Rich Interesting I imagine they are focusing on these cloud hashing for the forseeable future. When they can sell PH's of gear and deliver to them self that is about as good of a sale as it gets. I Imagine B-Eveven miner sales will be secondary to them when they are selling so much cloud mining. So good for cloud miners not so good for home/hobby miners is how I see it. |

The newest batch of S7 looks to be it could be undervolted for better efficient power usage. The A6 needs a controller, worse efficiency and less hash rate...I just don't see how the avalon would be a better choice. Maybe its a bit quieter...but once you're into this league of miners id think you would have a room dedicated to miners and power hookup.
If I can add to the negatives list: 1) Claimed MOQ of 10 from blockc (but the order screen will accept an order of one). 2) No tolerances on the efficiency 3) Blockc is not just the US distributor but the "global master distributor (ex China). On 1 it could be an error. With stating they will only ship ten there is no guarentee they will ship an order of 1 or if they will do a refund of purchase. I keep hoping to see the underclock. I see a picture above anyone got one that had tried any underclocking? Even a hint of what they can do would be much appreciate. |

I also need an S3+ controller board, one of mine is bricked. Im not sure how to recover it, i was going to try and buy a new one from Bitmain but i heard they dont even have S5 controller boards at the moment.
Put in a ticket/email to bitmain. They will give you instructions if you ask for un-bricking a S3 controller. You need a usb to serial cable. I don't have the instructions but they have provided them to other people before. I think they will do the same. |

The best option and most secure is a paper wallet.
You can make one via many websites, eg blockchain.info
Cheers
LondonTrader
If you make the paper wallet from blockchain it kinda defeats the purpose. Blockchain is a hot wallet.... so getting the wallet there for the cold wallet is not the best idea. There are much better way's to get paper wallets. Do not get them from a hot wallet or you still have all the security risks of the hot wallet you got the private key from (in your suggestion this would be blockchain). |

Got rid of the font size... a little to big. A online wallet or hot wallet is something you should keep spending money in, not a ton. This amount veries depending on the individual. Cold storage/harware are MUCH better for storing your actual holdings. Not being online or linked to a computer online is a good thing. |
