Have you checked the documentation page? this shouldn't be hard to set up or else it really needs improvements in terms of the user-friendliness, monitoring tools are usually 1-2 steps of clicking "next" and then entering in IP range to scan for miners and all your miners that have active APIs and could connect will show up.

The pool no longer has a server in Germany, only one in the U.S, however, o_solo_miner has a passthrough located in Germany


108ms is more than good, there is nothing to worry about.

This section is BTC only and thus it's ASIC-related questions only, but the answer is there is no problem with that either.

In what world do they sell S19 pro for 7.5k? well if you can source them for 7.5k you can make a fortune by reselling them without having to go through the trouble of making a boiler whatsoever, the S19 pro spot price in China today is 13.5-13.7k, to get 5 hash boards you need 13.5/3*5 that is 22.5K for hash boards ( ya you end up with an extra PSU and a control board but that's irrelevant to the case in hand).

So 22.5k + 9k for the heater that is 31.5k, I am not arguing it's a lot or is it worth it, I am just commenting on the verse you mentioned about staying poor, a poor guy will not even think about buying your system.


There is no "last" moment, do you believe in unicorns? those and timing the market have so much in common, your product is either profitable or it is not, the math is rather simple.

You take the mining process out of the equation and apply 1st-grade math, according to this website people in France pay about $60 a month to heat their houses in the winter, there are about 4 months in France where heating is needed, so that's $240 a year with the traditional heating system, so you walk up to that person who already has that system and ask them to pay $9000 which is enough money for 37 years.

Clearly, that guy's answer would be a no-no, so your next client should be someone who is interested in mining or making a profit rather than just saving money on bills.

That person would want the boiler to work 24/7 just as his normal miner would, so can this run 24/7 for 4 months? if it does - that person ends up paying the same bill, making the same bitcoin profit but saves $60 a month ( or whatever they pay to heat their house)


For this to work, the mining bill needs to equal to the heating bill, if at one point it isn't, then it won't work, it's like telling the tenant to pay $200 for a $100 bill so you can keep the $100, if the tenant knows his heating bill is $60 and you hit him with a $576 bill (based on 5 S19 pro hash boards that run 24/7 at 20 cents per Khw) they will either sue you or leave the house.

The investor will need to sell some or all of that bitcoin they made to pay for the difference between the $60 and the $576, if they made more profit than that, it's a win, if they made less, they would need to pay that using their own money, your boiler doesn't reside outside of the profit/loss territory, with this real estate investors example you make it sound like it's a free money printer which is not.

The investor will need to buy your boiler and keep the regular boiler, run some sort of a script that controls a relay or a contactor and it interacts with something like whattomine.com's API,  and then run something like.


They will also need to instantly sell the mined bitcoin or just enough to cover the bill, this will work great as long as the mining profit is great until it is not.

So again, really, this isn't for everyone, and your potential clients are very limited, this will make sense to the people who pay premium for heating, it will make little to no sense to those who pay a tiny bit of that $9000 you are asking for, but nonetheless, I admire your vision and the idea does have a lot of room to grow and expand, it just needs to be lower in price and fully automated.

As NFW mentioned, no port-forwarding is needed for mining, you may need that to directly access your miners over the WAN but that is a bad idea in the first place and there are better and more secured methods to access/monitor your gears, where I come from I'd say 80-90% of internet users are behind a NAT, we need to pay almost double the price to get a public IP, I don't know how things are elsewhere but my "educated" guess is that many if not most miners are behind a CGNAT.

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?

You can't possibly do that, you will need a large organization with unlimited funds to achieve that, there are thousands of links that lead to fake firmware everywhere, it's even worse now than when I posted the topic, so all we can do is educate people in this regards.

Personally I only trust the following firmware:

1- Stock (Bitmain)
2- Vnish (AwoesomeMiner and asic.to)
3-Braiin OS
4-Moded firmware made by fellow member thierry4wd

There are probably other legit firmware out there but the vast majority are indeed fake.

The above explanations are really good, but I do understand if confusion still persists. I'll explain it in a different manner, the pool knows if your miner can solve 1*1 it could solve 2*2, so every hash your miner submits is a possible valid solution to the current block the pool is trying to mine.

Since the pool needs to verify that you are actually doing some work and sending valid shares, it needs to validate them, validating every single share will be a waste of resources, so the pool will use what is known as pool difficulty to eliminate all shares below a certain threshold, by doing this it ends up with a lot fewer shares to verify, since the pool has the template it can tell if you were actually working on it or not, of course, based on the results you submit.

When I was explaining this to one of my friends he said if the pool needs to verify all submitted shares it pays for why not mine its own bitcoin? this is because it's a lot easier to verify a hash than to hash it.

if the hash digest is AAAA and you need a hash that starts with one zero, say you will start the nonce from 0 up (isn't how it's really done) so you will need to go
AAAA0
AAAA1
AAAA2
AAAA3
........
........
........
AAAA9 > 08c0e097e4728f628845d6d11fa0ab133725482cbd9f577b9ce994390b273f64   > you can try it manually here > https://emn178.github.io/online-tools/sha256.html

You need 9 hashes to get a hash that starts with a zero, your pool knows the AAAA, so it's kind of like you just tell them "9" gets you a 0, that would be easily verified by the pool, and then they add 1 share to your account so they would pay you for it later.

I quoted you both because you two have the same concern, don't worry about the timestamp at all, NO, you won't lose a block because your clock is half a minute late/early, you can even mine blocks with a timestamp in that past.

If block 100 is mined at 2:00 AM and you manage to solve block 101 with a timestamp of 1:50 AM, it will still be accepted, there are basically two rules for the timestamp of a block, it can't be more than 2 hours into the future based on your node network adjusted time, and it can't be lower than the median time of the last 11 blocks.

As for the online explorers, some might be showing the timestamp on which they received the block based on their own clock, some will show the timestamp that is in the block itself, clocks are never 100% synced so all this variation is completely normal.

I believe ship time is the time it takes for them to prepare the stuff and send it out, after that you should get a tracking number and how fast you receive it will vary on a few things.

I don't know the exact details of your order, I don't work for Zeusbtc nor am I related to them but I am pretty sure they won't be scamming you, it's probably a bad staff management they either forgot to ship you the goods or they did but they forgot to send you the tracking id,  but nonetheless, don't worry.

On a side but related note, I just sent a private message to their support team as well as the company owner himself, they should be contacting you soon.

Antivirus could be useless in this case, according to my experience and based on most stories I heard, the virus comes from second-hand miners, the miner will seem okay when you first test it "the virus is probably made to behave that way" and then eventually you notice the hashrate on your pool drops from time to time, it takes time to know you are infected, some people don't see it until a long period of time has passed.

So this isn't the average virus that screams out loud to bring attention, now how does it spread to other gears isn't something I am fully aware of, but for my farm and farms I manage/built for clients, I noticed the virus didn't show up when we start to use custom firmware and/or new bitmain versions with SSH disabled by default.

Of course, I developed a habit of Sdcarding any second miner I buy before bringing it close to the other gears, you can use a different spare router as the other methods require some knowledge, I also avoid logging into the miner before the Sdcard is done, so from the box to the Sdcard process only then I allow myself to log-in to that miner to flash a new firmware, SSH should be disabled or change the password, also right after you flash the new firmware make sure you change the miner's web password to a new password, not one you use on other miners ( at least until you confirm the miner is 100% clean).

By doing this personally and engorging my clients to so, I have not had a problem with any mining virus ever since.

I would sell it.

The M31s+ makes $23 a day based on your 8 cents per Kwh rate, you have probably paid $8500-9000 to get it, that is a 12 months ROI at best, and then

1- You don't have enough knowledge about mining.
2- We are far into the bull market.
3- Today's profit is far from sustainable.
4- Chips shortage is going to ease.
5- Difficulty will only go up.

You will need a series of fortunate events to actually ROI within 12 months or less, but hey, people say I am pessimistic, some people think bitcoin price will go to infinity and these expensive gears will ROI in no time, they could be right, we can only wait and see, I would love to visit this thread back 12 months from now.

That's great news, although I still don't understand how is that even possible, you mentioned that


by machine, you mean a non-miner machine? if it 'IS' a mining gear than how could it be more powerful than the rest?

It's not like a poor man will go rich running 5 hash boards, also, I'd guess a poor person won't be paying 9000 for a boiler or whatever you want to call it, don't get me wrong, after watching the prototype I don't think it's a stupid idea anymore, but I don't think it's a great one either, also as a client, I couldn't care less how much it cost you to build that boiler and at this cost and without having to do any math I know for certain that buying a normal boiler heater for $2000 and then investing the remaining 7000 in other mining gears or buying bitcoin directly will make a lot more economical sense.

Also from what I understand no hash boards are included, so if someone wants to add 5*19 pro hash boards they would need to pay $9000+ $20,000 to $25,000, this adds up to about $30,000, not sure if anyone spends that much on a water boiler bills, what is even worse, is you can only use it in the winter.

To me this product only suits rich people who own large houses with swimming pools, those people won't really care about the profit coming in from a few hash boards but they might very well enjoy the experience.

Nobody knows how many rich people will be willing to buy your product, you could sell as many as you have never seen coming, but one thing I know for sure is that your attitude needs to change if you really want to have enough clients to sustain your business.

Good luck.

Thanks.


If you can vouch for him and he agrees to be listed, I would certainly love to add him to the list.

I really have no idea, I could be wrong on this one anyways.


You should probably add more keywords such as virus/infected/hack, and you should be able to find posts such as this one


This quote brings some bad news to OP, some virus's versions lock you out of your control board, and this seems to be one of them, let's hope he gets lucky.

The miner won't connect if the address is not owned by NH.


Not that I still use NH but when I did back then you had to use the bitcoin address THEY give you, not just a bitcoin address,  white it's a different addy for everyone and you can even send BTC to it, your mining rewards are not sent to that address but rather are stored in NH database and then you can withdraw them to an "external" address, in fact, you can even use the same nicehash BTC address to mine other coins.

If you google this address instead 3BjMWfED7RJvtBPPikJpweDT6A9xRW952x you will find that many people were infected with a virus that uses this address, I have personally had gears infected with a virus that mines to that NH address, so I know for a fact that mining address made a lot of coins, but if you check on the blockchain it has 0 transactions on it.

2 blocks left, so in 20 mins give or take we shall have a 5.8x% spike, do I bother? not a single bit.


Mining profitability as of today and how it has been for the past couple of months is unrealistic and far from sustainable, if someone feels the heat from a 6% spike then they shouldn't be mining in the first place, I look at the difficulty figures every now and then and think to myself that as long as it doesn't do a 100% increase then I would still make more profit than I did last year.

Will this last forever? absolutely not, we know two things for certain

1- Difficulty will only go up (regardless of how fast)
2- Price can't only go up

This is why I take every chance (including this one) to warn the newcomers that mining isn't all sunshine and rainbows as it seems now, investing 13-15k for a single S19 pro miner is a terrible idea, it isn't going to generate 1k profit every month for the rest of its lifespan, well, it could in theory but there is a higher chance that it gets hit by a lightning strike than you making 1k profit every single month.

What is the average hashrate labeled as (GH/S(avg)) at the topic of the miner status page?



If it's within the normal range of 13.5-14.5th then you don't need to worry about the readings that show at the bottom for each chain individually, and most importantly would be the accepted hashrate at the mining pool, such weird readings usually go away by flashing a firmware, but if they don't really impact the actual hashrate - just ignore them.

That's pretty strange, when you use a new control board, it's like buying a new miner so this problem should have been solved, the only two things left to troubleshoot would be the fan 4 pin wire, it's a 2 pieces wires, the fan isn't directly plugged into the control board, so the wire from the control board to that junction could be faulty, the second thing would be the PSU, while the fans get power directly from the control board, that power still comes from the PSU, there is a chance that the power is dying/dead and can't feed enough power to all 4 fans.
