too bad so 3795 x 1.276 = 4842 to a legit usa buyer.
jeesh lets say they come sept 1 vs sept 30
and they do 68th at 3350 watts.
about 80 kwatts a day
at 1 cent power that is 80 cents
at 2 cent power that is 1.60
at 3 cent power that is 2.40
at 4 cent power that is 3.20
at 5 cent power that is 4.00
at 6 cent power that is 4.80
68 x .00002416 = 0.00164288 btc or 17 a day - 4 = 13 a day
4842/13 = 372 days So I am still facing gear that is cost prohibited
but even in china it would be 3900/13 = 300 days at 5 cent and
3900/14.6 = 267 days at 3 cent. this is a hard sell.
5 s9's are 1700 do 70 th or 0.0016912 btc a day or 17.28 usd a day and burn 156 kwatts at 3 cents that is 4.68
so 17.28-4.68 = 12.60 a day
so 1700/12.60 = 135 days. and only 1700 out of pocket vs 3900.
I just don't see the pricing as working.
I have handled all this gear. it all breaks down at about 10% a year.
I hate having so much idle power only 110 of 150 kwatts filled. But companies are holding the line at over priced items.
I will wait till the inno ships it is due to ship by this Saturday. lets see if they ship on time.
Once that unit arrives I will decide what to do next.

DAP is delivery at place, duties/tariff to the buyer. DDP is Delivery duty paid.
Thanks for clearing that up for me. |

Has anyone tried using a splitter on this miner? I feel like it's a horrible idea but figured I would ask first. I got a good deal if I want it for the 54th models of these m21s's but... I run all my miners on pdu's and even at 3240, I don't see how this can be reliable plugged into a pdu pulling that much power. Unless the power cord coming out of the unit split in 2 (Sort of like the bitmain s17's do) and I can plug them into each bank.
I use these https://www.ebay.com/itm/L6-30P-to-C19-Molded-Power-Cord-10ft-220V-250V-30A-Ships-Free/202648792458?direct to the wall plug. so on a 30amp circuit they use 14-16 amps. I still can make it work well since I have 9 circuits to a 225 amp sub panel. And six subpanels 9 x 24 = 216 which would be hard on the sub-panel and can trip it on a 95f day. so I do 2 of these at say 2 x 15 = 30 and 7 x 24 = 168 Thus 168 + 30 = 198 which is easier on a 225 sub panel If we went all m20s I would truly be afraid of a meltdown since I know we run from 217 to 227 volts. |

What is DAP or DDP?
And does the 3938 price include trump tax if shipped to New Jersey USA?
Let me talk to buysolar about it.

I mine 910th btc and 11gh ltc.
about 80kwatts on btc
about 20kwatts on ltc.
I will continue to do it simply because all that gear is paid off.
yeah right and to complement you, unicorns do exist too. Yep I do exist and here is the ltc but there are not many people in my set up  |

I have a very new state of the art ryzen 9 3900x cpu. I use it to mine at nicehash it auto converts all earnings to btc. This pc earns 55 cents a day in btc. So if I had 20 of them I would earn 11 dollars a day or 77 dollars a week. This cpu costs 500 usd. If I worked at a low cost build with it. It could be built for about 850.
the two high-lited in rectangle are a ryzen 9 3900x and a threadripper 1920x they do from 1300 to 2400 hash on nicehash and earn around 85 cents a day they convert all coin to btc so it is under 7 dollars a week add in the gpus it is about 17 usd in btc each week. not counting your power those rigs = $$$ it would take more then 2300 to build them |

Unless bitcoin forks to a gpu algo (lol) or another ethereum hits, 2016-2017 levels of profitability are not coming back. There's also a ton of hardware now waiting on the sidelines to hash. Also eth will go POS (soon   ). Pretty close to my thoughts. Here is another way to look at it. Bitmain was selling s9 for 3000 in dec 2017 when coins were 20000 and diff was 1.4 An s9 made 0.0024 btc a day and that was 48 dollars a day 3000/48 is about 60 day roi. Now an s17 makes 0.0012 btc and that is 12 dollars a day. 3000/12 is about 250 day roi. We are not close to December 2017. Also 1 s9 burns 1300 watts And 1 s17 burns 2225 watts. Once you factor that in it is even worse then my 60 day to 250 day comparison. More like 66 days if power is 8 cents for the s9 in 2017 And 414 days if power is 8 cents for the s17 in 2019 Basically gear is really over priced right now. I’m have 110 kwatts running and 40 kwatts of idle power due to high priced gear. We can go to 350-400 kwatts and we are not adding a transformer due to high priced gear. Basically gear is 2x what it should be. |

Okay more amps not more volts.
So you need an atx or maybe a hp 1200 server psu.
I am dead set against using bricks and rasp pi’s with this gear. But I am simple miner not the designer of this.

Anyone know whats the deal with Nicehash, Ive been always mining to an external address, they don't say
anything about what happens after sept 10, do they just transfer everything over or do I lose everything + the rest of
the bitcoin owed to me when they got hacked? cause I don't have an email attached to my address?
If you load the newest miner you can just put the same address in and I think it will work for you. I have three old addresses owed coins I will test it out. |

It's only profitable to mine if you have free or dirt cheap electricity.
I'm not a miner, but I've certainly read enough about it here and have seen tons of videos on Youtube. My understanding is that even if you have free electricity, it would still take a long-ass time to recoup your investment on the required hardware. That's if you're just starting off right now with no mining equipment. Bitcoin is definitely not profitable for an individual to mine unless all the hardware is paid off and electricity is dirt cheap (Philipma1957 would probably say the same thing). All of this is why I took an interest in proof-of-stake coins, which doesn't require anything other than a desktop computer in order to earn coins. True, it's not real mining but I got into the game extremely late. Wish I'd heard about and taken an interest in bitcoin years ago. I have 4 cent kwh and its boring now. Still profitable but I can't find a reason to expand my mine, I have 100 amp service maxed out at 80 amps and even with cheap electricity nothing is looking great. I wanted to run a 400 amp service but i really can't find a good reason. 90% of my gear is 3 years old expect for a few z11s and so its all paid off, I should sell my gear.
Pardon my ignorance (which I freely admit), but what are you mining? Cheap power is important but we are now in the overpriced gear stage. I have about 910th in Btc I have about 11gh in Ltc My deal is 50/50 coin split. And all the the gear is just about paid off. But I can’t get new gear at a decent price. We could add 40kwatt in gear bringing us to 150kwatts, but prices for new are too high. We could also put in a second transformer and go to 350-400kwatts. |

But what is the extent of the possible bitcoin ban in India? Does it include mining? or simply bringing coins? Have You considered the other asic miners? Given your borderline electricity price you want the most efficient unit, not necessarily the one with the biggest TH/s (in fact always divide watts with TH to get the most efficient one).
If you do this math for this unit it gives 64, which is a tad higher than other units. take a look at the M20 and S17, seek the most efficient miner even if it means running at half hashrate.
Perhaps setting your miner in a different country with cheaper electricity would be more wise.
He is in a tough spot 8 cent power can be a loser at times. He is in a country that has banned some crypto activity. If I was his financial advisor I would tell him to not bring gear into India 🇮🇳. The risks may be too high to be worth while. |

Batch 2 In-Stock units are now available for order, all orders ship within a week!
do batch 2 look different then batch 1? Yes, the case was completely redesigned for Batch 2. Maybe I get one I have two from batch one may as well get one of these. |

because people have 208 volts and at 208 volts you get 3360/208 = 16.15 amps
and people have 220 volts and at 220 volts you get 3360/208 = 15.27 amps.
my main farm does 217 to 227 volts
my 2 m20s are right next to a huge set of 3 fans which blow cooler air directly at the 2 m20s and the 1 m21s
since all three are over amps when we sag to 217 volts. they are all at 15.48 amps.
I have 3 racks of gear each with 5 shelves and about 7-9 units on some.
if every rack was an m20s
rack 1 rack 2 rack 3
fan> 1234567 1234567 1234567 > fan
fan> 1234567 1234567 1234567 > fan
fan> 1234567 1234567 1234567 > fan
fan> 1234567 1234567 1234567 > fan
fan> 1234567 1234567 1234567 > fan
my units would be at risk of wires melting in a pattern such as above.
even if you magically run at 230 volts and never vary you are 3360/230 = 14.608 assuming that the psu never ages (it ages) and no power will be perfectly stable at 230 on and on and on.
it will flux.
so if the psu is perfect
if the volts are perfect
if you keep room cool enough
230 volts should be okay.
frankly I would prefer they set gear to run at 65th and 3100 watts

Got 10 newpac's now, should i change suggested diff / how can i calculate the suggested diff? 128 for each newpac?
Set the bat at a diff of 128 run the sticks for a day. Then set the bat at 256 run the sticks for a day. Then set the bat file at 512 run the sticks for a day. Then set the bat file at 1024 run the sticks for a day. Compare the results. Basically some pools will set the diff for you. Others want high numbers for diff. Most likely a bat set from 128 ,256,512,1024,2048,4096,8192 they all will have close results. Some pools will like higher then that. Nicehash wants a diff set to 1000000 which is a p.i.t.a. For the sticks the the R606 I go from 128 to 8192 and don’t have much difference in any of them. |

There is no problem with lost hardware wallets, but only with lost seed/s in combination with lost hardware wallet. That's not accurate. There was a recently revealed serious flaw in Trezor devices, which means they can be compromised relatively easily by an attacker, and all funds stolen. See here for more information: https://ledger-donjon.github.io/Unfixable-Key-Extraction-Attack-on-Trezor/. Trezor have accepted that this flaw exists, and there is no patch for it. The only way to mitigate against it is to use a long and truly random passphrase, which few users do. A minimum of 37 random characters is needed to replicate the security achieved with a 24 word seed phrase. Although no such vulnerability has been demonstrated on Ledger devices, you shouldn't ever assume they are 100% secure. You should never assume that any security set up is 100% secure. It may take several weeks and some very expensive high tech equipment, but coins or seeds are potentially extractable from any hardware device. If you lose your hardware wallet, you should your coins to a new wallet as soon as practical. "Printing your keys to paper" also has many potential vectors of attack, and it is far easier to mess up doing this than it is using a hardware wallet. If you want to use paper wallets, that's fine, but make sure you understand how to create them safely and securely first. Nice info. Basically long passwords do fix it. The biggest problem is still true for every mechanical wallet some thug holds a pistol to your head and says open it or else. So basically if you have three of them one with under a coin. One with 2 to 3 coins. And a third one in an emi faraday box in a safety deposit that has the serious coins. |

I think you are worrying for nothing. Most of those tainted coins are some Chinese drug lords and I am pretty sure they wouldn't bother buying any mining gear. If they really wanted some mining gear for some odd reason, I think they would just buy some new ASICs or GPUs instead of something second hand.
Also say they wanted to sell some of their BTC privately doing a person to person meet. Some new adopter decides to buy some bitcoin from them and they are sent the tainted coins. Those coins then would get tainted and might get flagged by some exchange however most people aren't going to check prior to a person to person crypto meet where the coins are coming from. Its not illegal doing a person to person meet unless its for a large transaction. So the buyer did nothing illegal here.
This is no different than someone selling a car to a drug dealer and that cash was original used as a drug money. The buyer has no idea the person was a drug dealer and no way to tell where the funds came out. Will the police come and take the cash away from the seller? Probably not.
I check the listed addresses and I have decided that buying and selling coins directly to a major exchange would be safe to do. |

I have been reading articles that when Etherium 2.0 is released in 2020 you will not be able to mine Etherium with GPU miners. Is this a definite thing or is it still just up in the air?
If we will no longer be able to mine Etherium does this officially make GPU miners irrelevant? Or is it still worth building them for @ home solutions to mine other coins and possibly new coins that could be profitable?
I currently have an 8 RX580 rig that can't really mine anything profitable except for Etherium. (not sure if this rig will be useless in 2020 or not).
I am looking to build another rig with 8 GTX 1070ti cards that will give me more flexibility to mine other algorithms.
Would it be foolish to buy 8 brand new GTX 1070ti cards at $479.99 a pop and build a $5000 rig with the future of GPU mining and where it stands? Even if I buy used the rig will cost about $3800. Just trying to see what peoples thoughts are on this. I am willing to gamble, but don't want to gamble if there is no chance GPU mining will be relevant within the next 2-3 years and we already know this.
If someone can give me an idea of what I am gambling on by continuing to expand my GPU miners in 2019 that would be great.
No it is not official. 2-3 years in crypto is really long. The correct answer to your question is maybe. |

Raven is switching algos in a month, this will become useless, if it even exists.
Please link that switching info. To op so far every fpga sale attempted on this forum has been a bust. No one has done well with pruchase of fpga's. Fpga sellers have been too slow to market and they most often don't offer the best algos. |

Were you opening multiple tabs then going to merit them? Easy to get confused and open the wrong one, especially if you only accidentally clicked the merit link while scrolling. You would have to take note of the receivers name, and I know I rarely double check I have the right person... never really though to.
I did always find it a little odd that the post you are meriting doesn't appear as a preview or quote somewhere on the page. It could even be a feature you could toggle for those that don't want it.
Ah the ipad mini 5 can do weird shit. I simply don't understand how it happened. It is annoying that he got some merits when he should be tagged |
