Sigh.... Please ref https://bitcointalk.org/index.php?topic=2415854.msg24714338#msg24714338TL/DR Summary:
- You CANNOT meaningfully mine bitcoin with your PC or laptop no matter how powerful it is.
- You CANNOT meaningfully mine bitcoin with your tablet or phone no matter how powerful it is.
- Mining apps for your phone or tablet that claim to mine bitcoin are almost certainly scams.
- You CANNOT find software here to mine bitcoin with your PC by itself.
- You MIGHT be able to do one of the above with altcoins, but such discussion goes into the altcoin mining section.
- You CANNOT find or post software here to mine on other peoples' PC without their permission.
It would be a very very pointless enterprise.... Your share rate would be so incredibly low most pools would treat it as a dropped or offline connection  |

150kw is getting into 3-phase territory but still very practical for single phase service. It comes down to cost of the panel (size and amount of copper in it) and if the power company needs to supply you with a different service transformer to feed the building. As Mikey said, go with what is cheaper.
Is drawing 150kw on a single phase an issue for the TDU since it is extremely unbalanced on the transmission lines, right? I assume that "TDU" is your utility supplying power to the building? If so, yes and no. Yes it is a load on only 1-phase of their (usually 3-phase) transmission lines BUT it is their job to monitor the lines and divvy up the loads on them between you and other customers so no it should not really be an issue for them. If you are in North America, depending on what kind of power is needed for other businesses nearby, their '3-phase' may not exactly true 3-phase but rather 3-phase created by using a 'wild leg' as referenced to Neutral. Voltage across all 3 or any 2 lines is the same. Voltage from either L1 or L2 referenced to Neutral is balanced to 1/2 the L1-L2 voltage. For 208 VAC that is 110V for L1 or L2 to Neutral. Voltage on the 3rd or Wild leg referenced to Neutral is much because it is is NOT reference to Neutral. The 3rd leg is supplied only to places needing 3-phase to run motors, refrigeration, and other application requiring it that are powered by all three phases. If that is the case the utility is already supplying single phase power over very heavy lines feeding several other locations nearby. Would they prefer a load split across all 3-phases? Sure, but it should make no difference in what you pay. |

If they all have it by now then why is the virus idle for so long? Why doesn't it screw all miners asap? The answer is right in front of you: If it immediately affected all miners one would notice it and then take immediate action to remove the malware. By waiting a few days/weeks before re-directing your hash the malware is free to spread to other miners. You should apply the SD process on ALL of your Bitmain miners to clean them up. |

When you buy used gear, always flash it back to stock firmware following the sd recovery method. Don't even think about it, do it.
Exactly. Look at it this way - a miner is ran by a small built-in PC that uses flash memory as a drive holding the operating system and miner software. Would you buy a used PC and put it on a network without first wiping the drives and installing fresh copy of the OS? I hope to God your answer is a resounding: "HELL NO -- intentionally or not, who knows what malware has been loaded onto it!" Same logic to wipe all storage and re-install fresh OS & programs applies here. |

Short answer: NO
Accelerator sites are ran by pools with thousands of miners behind them. They work by including requested transactions in new blocks they work on. Given a large enough pool that gives a good chance of your stuck/slow tx to be processed quickly.
A single miner, hell even enough miners to give 10PH, have a very very very low chance of finding a block -- far too low of a chance to be a successful solo operation much less one able to accelerate Tx's.

"Happen to it"?
As I said, what you describe, L1-N-L2 is how power is fed to a house in NA and Ground is tied to the neutral at the incoming power junction. Appliances that use 220v just use L1 & L1 with ground so aside from it working, nothing will 'happen' to it.

That is exactly how power in North America works. Here Neutral is only for making the 110v circuits.

What is the VAT? And VAT tariff? Value Added Tax. The amount of VAT all depends on which non-US country you live in. The USA only has the Trump Tariff. |

Then check what Blokforge.com has in stock. They are in Mesa Arizona (even have walk-in a store there) and primarily carry new gear but have some used gear from time-to-time. I've used them since 2017 for all of my new gear purchases (primarily Avalons) and they are excellent folks to work with. |

They claim this reduces the effectiveness of ASICSs as they can't do massive parallelization. Bullshit. ASIC-based miners are MASSIVELY parallel processing devices. Each chip in a miner can have over 256 cores and each miner can have many hundreds of chips with each core processing 1 hash for every 2 clock cycles. Well over 100 chips per hash board is very common. That is how they achieve from a few TH/s to over 100 TH/s throughput with a modest few hundred MHz clock speed. Yeah there is a limit to how many chips can be effectively fed data per controller that that is not a serious limitation. |

Bad idea to use only 2 power connections to a hash board. You will be overloading the pins and wiring from PSU to the connectors. Even using all connectors there is very little margin between maximum rated current per-pin and actual current the boards draw. Yeah running that way for a very short time *might* work but still a bad idea because depending on the PSU used there may too much voltage drop through the wiring.

Yes, there should be no problem at all, you probably didn't find anything on google because nobody bothered to talk about it because it is so obvious? mind telling me what could go wrong mining behind a CGN?
on cgnat you cant do port forwarding and i thought for mining i needed port forwarding Not when mining using ASIC-based miners. You can assign ports to connect through but port-forwarding is not used. Considering this is a Bitcoin-only area that means ASIC hardware so - no problem. |

Try running cgminer from a different directory as a separate instance just for the BF sticks?

If they were running fine until recently then you picked up a virus/malware from *somewhere* and how to fix still needs to be addressed (by others here).
|
|
|
|

Did you buy the miner (a long time ago) directly from Bitmain and this started recently or did you recently buy the s9 used? If the 1st then malware has infected it. If the 2nd - the miner was sold infected.
Either way IMMEDIATELY isolate it from your network as several of the mining malwares out there will search for more miners on the network to infect... Others here will have to explain how to fix the issue as I no longer run any hardware from Bitmain.

As a side note, whoever decided on calling it PoS no doubt knew that with very few exceptions, most of the altcoins developed for using it would be Pieces of Shi* destined to fail & fall by the wayside. Kudos to them for having a good sense of irony and humor  |

Someone lacking in google-fu?
Just do a search using 'Bitcoin Proof of Work' or 'Bitcoin PoW' and you will get a ton of answers...
As for making money, mining and trading.
Mining is only if you have good rates for electricity and a place to house the very loud and hot miners. Trading is if you do not have that.
