With the exception of the Avalon A7 which uses a RPI as its controller, there isn't any Bitcoin miner that is profitable and needs the RPI to control it. The Gridseed is mainly used to mine LTC and it isn't too profitable (maybe a couple pennies if you're lucky). Don't even think about mining BTC with it for profit- when it was released, the miner had below-average efficiency for its time. Now it's just an energy hog and mostly a collectible.
Additionally, if you are talking about Scrypt or other alt coin mining please move this out of Bitcoin mining speculation.
Shall I take it as ,,, THERE IS NO PROFIT WITH BITCOIN MINING  ? If i can make 2 or 4$ a day, with mining as profit, that will be great . How much does your power cost per kwatt? 8 cents a kwatt means you have a chance to profit. Bitcoin miners are very loud. The Avalon 741 is about 800 usd. Add a rasp pi and a psu it is near 1000 it make 8 or 9 a day. Good luck buying it. Can't you save money by flashing the Pi yourself? I recall I saw a guide for doing that by Avalon and it seems that'd save you a lot over how much Avalon charges. For PSUs you can get a decent server psu that can power it under 100 or rarely 80-50, so it'd be closer to 900 if you're lucky. |

Realistically speaking the S7 or any miner of that generation will no longer produce much at all even at the low electrical cost of 4-5c per kw. Difficulty is rising too fast as it is. I'd recommend an S9 at Bitmain prices or some Dash/Litecoin equipment if you are lucky enough to snag one at manufacturer prices.
I hope you are aware of the noise the S9 makes. It's about as loud or more loud than the S7 due to even higher chip density; if that's an issue, the R4 will work.

so all receive item right ? see like no scam hre , i going try buy one .thanks all for review
Seems like that's what's happening. It's good to support the lesser ASIC manufacturers too, even if they perform a little worse as it's always great to have some competition to keep Bitmain on its toes. |

It's all up to whether or not the board can support a PCI or M.2 PCI Interface and whether or not you are willing to program the board to actually run with the GPU as it will most likely not work out of the box. Most devices like this could save energy if they work, but they are also very expensive as most of these boards are development boards- best to just buy a normal motherboard and CPU.

Have you seen the site bitcoin.sipa.be yet, Phil? Seems like a somewhat good indicator of difficulty that has charts somewhat like the ones on Bitcoinwisdom. Not sure how accurate they are, however, and they don't seem to provide any specific values. |

Just keep in mind even though they may not need the common 6pin plugs on most GPUs you still want enough power to run the entire rig- depending on how much power it draws, you should be drawing 50-70% of the total maximum rated power your PSU can handle for maximum efficiency. Yes they can run at their max power, but they aren't at their efficiency peak even if they are rated 80+. In your case the 550 runs at average 50W, so 5 cards + CPU that isn't mining = approx 300 or so watts. 600 would be a good PSU wattage. If you want to cheap out on a refurb 80+ EVGA has a 600w for $20+ free shipping in US rn: https://www.evga.com/products/product.aspx?pn=100-W1-0600-RXAs for coins XMR can be profitable, if your controller CPU is decent it can also hash XMR for some small profit. |

Hello everybody!! I´m new in the mining game, and I want to show my 6 GPUs mining rig´s design, I designed it, I printed it, and I mounted it!! It works fine at 2020 Sol/sec with 6 GTX 1060 6GB.  I designed it in hexagonal pattern to improve the heat dissipation, I hope do you like it!!! Regards... man that is a killer looking rig i really like how you made it look cool and not like most other mining cases I Love this design, very creative. one question though, why aren't the risers powered? If the cards are powered by 6/8 pin plugs and aren't strictly powered by the pcie connector, there shouldn't be a need for the risers to be powered. Seems to be the case here. |

The problem is they don't respond very much to any questions or even order requests, and nobody has really been able to get their hands on a heater unit even though many have inquired. Looks cool and possibly practical, though, hopefully these guys get their production and customer service up to speed soon.

Get yourself a Dehumidifier!
Electronics and damp do not get along and could casue a fire risk!
This. They usually don't cost too much and for a few bucks more you can get a dehumidifier that automatically empties itself. Not much need for anything else in this scenario IMO. |

The gaming card is OOS right now unfortunately. If you browse r/buildapcsales on Reddit and set the bot to message you whenever a post for a 1080ti comes up you can snag very nice prices for GPUs there. IIRC at some California Fry's or Micro Center last week a refurb 1080ti sold for ~600 or 500 |

I have a GTX 1060 myself and it barely makes a profit if I was mining. This might be due to my high electricity costs of about 30 cents/kWh but my recent calculation for my revenue was about 1€ worth of Ether but paying about 60 cents in electricity, so a net profit of about 40 cents a day. Ethereum requires a huge amount of graphics memory, about 3GB and soon more. Therefore cheap cards cannot mine Ethereum reliably as they often lack enough memory. To cite a post from stackexchange ( https://ethereum.stackexchange.com/questions/426/what-is-the-current-dag-size-when-do-we-expect-to-hit-gpu-limits): "The 3GB limit will be hit around mid-April 2018". This means that from April 2018 on you need atleast 4GB video memory on your GPUs to mine Ethereum. As a rough approximation, I'll take a card of 200€ and expect a profit of about 50 cents. This gives me a ROI time of 400 days. It takes me over a whole year running the card 24/7 to barely break even. Factor in the noise and heat, you probably do not want to do this in your own room or appartment. The only chance you have are other altcoins which are not as memory hungry. Mining those early on might give you big rewards when they hit an exchange, but you could also end up with a net loss because the coin does not gather interested folks and fails. This will leave you with a huge electricity bill and little to no value in coins. Unless you have super cheap electricity or super cheap hardware, it just does not make sense to get a dedicated mining rig with such a low budget. Theres still profit to be found in these cards but you just have a very high electrical cost. Most people I know that mine in the US have costs around $.10/kwh and I get around $.07/kwh. I wouldn't mine at anything above $.15/kwh as the profit there is just minimal. You are right about the DAG size, but in your case electrical cost is a much larger factor. |

It's either Bitmain and this risk you described or you pay inflated prices for the miner. There's risk involved, absolutely, but most people like me just take it. There are many new people in the mining scene but it really doesn't take much to know how to care for miners and how to use them.

the squid is amongst us now ... everything smells so fishy, 4800 GS top call, ICO's sucking the suckers out of the lucrative IPO market, coordinated chinese "ban" FUD across all US financial media ... they've grown a new tentacle and it's labelled crypto-control
This was going to happen eventually and we are just now feeling the impact of this new tentacle. The question is how we respond to it and what happens next... |

ICOs had to go either way, and it seems this is how they will go away. Keeping ICOs long term is generally bad for crypto anyways as there's lots of scam ICOs and ones that just never reach their planned goals, it's good that this is happening but it comes at the cost of a worldwide devaluation for crypto. Will we get out of this? Most likely yes.
|

Even if it takes a drop in crypto price for ICOs to finally die off, it's worth it in the long term. Eventually there would've been a big enough scam ICO that would've gotten enough attention to possibly make price go down even more and it would've gotten Bitcoin more negative publicity.

can GTX 1070 mining dash?
NVidia GTX1070 can mine every cryptocurrencies : only AMD GPUs cannot mine some. Lol what is this bullshit? Unless there's some new coin called CUDAcoin that only allows Nvidia gpus to mine on the chain, all AMD GPUs can mine the same algos that Nvidia GPUs can mine on. The only real difference is efficiency and hashpower. The 1070 can mine dash but X11 ASICs far outperform them. Nicehash is your best bet for the most profit as it switches algos for maximum profit with a small fee. |

Monero uses a completely different algorithm than the L3+; the L3+ mines Scrypt. Monero uses CryptoNight and is completely incompatible with Scrypt, hence the numbers are fucked up. The calculator is right for the most part if only you actually had that much CN hashpower.

I hate to be a Debbie Downer but I do not like the risk/reward for btc right now. If we manage to break through $5000 I see a maximum of $5500 to $7000 before a major (meaning painful) correction. I am talking about $2500 to $2800, 50% correction or back to the weekly 20 MA. You know it will come, we just don't know when. I would rather wait for a huge discount to buy. I hope I am wrong, really, but I doubt it.
Cut
It still doesn't hurt to dip your hands into the cookie jar and buy some Bitcoin right now. It's never a good idea to put too much in at one point anyways, and if you only buy a little now and buy the rest later it can't hurt- I also expect we probably won't break $5000 this time around, and we will continue on a temporary downwards trend. |

For a cheaper PSU you can try a DPS800 and a breakout board. Not sure how much they are nowadays but I got mine about half a year ago for $35 and they're built like a tank + quiet. Their peak power is 800 watts 120 and 220+ is 1000 watts, and they are also 80+ rated IIRC.
