I have very limited knowledge in this field, but I am certain your guys don't need "formal training" if they are good at what they do already, wndsnb is now professional in hash board repair, I don't recall he took any courses, but he indeed is very talented in his field and was able to quickly learn how to deal with all that mess.

I got nothing against "special training" to speed things up, but I don't think that kind of training is available anywhere outside of China and maybe Russia, to send 2-3 guys it will cost a few tens of thousands of dollars, since you have the tools (judging by your current business) you can just buy a 1-2 working miners, and a few dead hash boards and get your guys to self-learn, the resources online are somehow limited, but they are there nonetheless.

Your earnings in BTC will depend on a few factors, the short term earnings will be greatly affected by the pool luck factor and the transaction fees, the long term earnings will be affected by the same factors + difficulty, and difficulty in general only goes up as far as the long term is concerned, most online calculators are fairly accurate accounting for all different factors and based on the current difficulty and average recent block fees with 100% luck.

You can use Whattomine.com or Viabtc profit calculator and set your power rate at 0 so that it won't affect your final earnings, the numbers showed there are pretty accurate to a good degree.

FYI and for some reason, CK proxy doesn't work well with other pools, I did try it a while back and it's far from stable when running on Viabtc and Binance, it did run well on Cksolo pool but did not on the two pools I tested, but do your own testing tho.


Also, I am not sure what do you mean by " able to display stats" but you do get the number of clients connected to that instance you running, and the miners that connect to you will see their status on their own Cgminer (like diff, accepted shares and all that), the proxy screen itself is just a command-line interface that displays the number of peers connected, share from x was accepted or rejected, a new block template/work is received, I doubt it logs anything unless you set up the database part.

Nothing really falls in between, the S9 does on average 80w/th with custom firmware (as low as 72w on some gears if downclocked really well), the M21s is about 60w/th, there is nothing that does anything above 60w and below 70w which I would recommend to anyone, if the M21s are above your budget, get S9i/S9js, or you can always mix two gears, maybe fill 30kw with M21s and 70kw with S9s, that will give you an overall (in between) option.

Budget will be the next point i consider, if budget is limited I will go with S9j or S9i, that will give you about 800th or 4.5k a month based on the current figures.

If budget is flexible, i would go with Whatsminer M21s, that will be 1.15ph or 7k a month, total cost will be at almost double 40$ per th vs 20$ plus for S9s.

However, the M21s will most likely live a lot longer and you will have a lot less gears to manage, less wiring and whatnot.

How cheap? every cent matters here, another point you need to consider is your budget, picking the "right" piece of mining gear isn't based on just one factor, you can buy an old  T9 for maybe 100$ and hit ROI in 2-3 months, but then you can only make about 2.2k of profit a day (before the power bill and rent) while consuming all those 70kw, on the other hand, you can get the 30w/th gears and make a few tens of thousands a month, but your budget needs to be so high and ROI won't be great, finding the right balance of everything requires a lot of information.

If you are able to provide this info, then we can talk, keep in mind that nobody will give you the "best" gear to buy, but at least you will be able to use the information to make an informed decision.

God bless that storm.


The latest update from Cambridge study puts the U.S at 35% of the total hashrate, it's a bit outdated since the last update was in August of last year, the U.S now has (easily) 50% of the world hashrate, my guess is that by the end of this year the number will jump to 65-70%, something that even China failed to do a few years back.

I won't be surprised if in 2-3 years 90% of the hashrate will be located in the U.S, eventually, those mega players that can secure 2.5c per kWh and have almost "unlimited" funding potential will kick the majority of the other players outside of the game even those large players in some countries like Russia and Kazh, fun times ahead.

Pace is back to 95% and only 31 blocks behind, maybe some large farms are having power issues or something like that, price is up 10% a drop like that in difficulty makes exactly no sense.

You make perfect sense, I do not understand the logic behind buying gears at such prices, it is either they do not understand shit or they know something we don't.

Clearly when gear prices fall only 10% and btc price falls 50% while diff keeps rising, you are better of just buying btc.

@stompix

I am glad you you did not think I was so mean.

Difficulty did enter positive zone, we are 3 blocks ahead, only a few blocks to go and we should hit a small 0.1% - 0.2%.

The big boys have the newest mining models and somewhat a cheap power rate, it is still a long way to go for any of them to slow down, we need btc to hit 10k for them to start feeling the pain.

If that does not happen then even 2x difficulty will not slow them down, maybe some U.S new laws regarding mining will hit them somehow?  If that does not happen, we are screwed.

60k is peanuts, to make direct orders from the manufacturer you will need at least 60m.

OP, let me know what type of mining gears are you looking for and I will recommend someone.

Why on earth would you want to use Antpool? Please do NOT, it is a rip off.

Regarding other pools, you are probably making a mistake somewhere, post a screenshot of the details you entered.

Lol that did sound mean i suppose, i missed a small (NOT) in that sentence.

Well the pace is at 99.5% , we could get a flat or a small positive increment, but the speed at which the recent blocks were found suggests we hit a large positive in the next epoch.

Anyone with even half that power rate should not be even remotely considering mining, you got huge players with 2.5c , many folks with free power, the unlucky ones are at 10 cents, 400% more fees on top of that is just crazy, it doesn't matter what Bitcoin price will do, mining at such rates is asking for trouble.

I remember you mentioned 15 cents or something where you live, I know my memory is corrupted, but I hope you are paying those 40 something cents.

This is how pool mining works, there is no duplication because the pool is giving a different block template (section) to every miner to look for the magic number, no miner is redoing the guessing of another miner.

I hope things are clear now.

With custom firmware the S19 pro can easily do below 20w/th according to one of the devs at vnish, so efficiency wise i highly doubt intel chips will beat that. So the cost of final products will be the judge.

As far as quality is concerned, I have to agree with you, although most issues are beyond the chip level, so we do not really need new chips to lower that failure rate, we just need better "everything else".

Microbt seems to be the only manufaturer with proper quality control, even the new Avalons have high failure rate, it is annoying given how expensive these gears sell for.

I believe he is talking about the pool level not the whole network, if all miners work on the same block template then finding a block will be a lot slower for that pool as a whole.

Assuming by "pool" you really mean a "pool" and not the whole network, then ya mining pools do have something like that, the pool won't send the same block template twice, any small detail you change in the block template opens a whole new door of non-overlapping "guesses".

Bitmain has a working product that intel does not have yet, personally, I can't take the above table any seriously until there is a finished product all of this is unreal, the chip level is the most important but there are many other factors, the production capacity and final cost are two important things that we can't ignore.

I can't speak for these ino PSUs, but my Whatsminer M21s and M20s and Antmienr S9s work pretty fine at your said voltage, however, I had a similar issue when the humidity levels were not controlled in my farm, I lost a dozen PSUs and hash boards in one night, hopefully, yours is just PSUs.

What I do now is point some of the miners' exhaust to the cold side of the split room to keep the temperature high enough, and I have a few of these > https://www.amazon.com/dp/B07FBCTQ3L to watch the humidity and temp from home, it also gives you a nice chart showing humidity temp recorded in the past so you know if your farm needs adjustment.

Another important factor to control humidity would be the room pressure, make sure it's controlled as it makes things a lot worse.
