what do you mean ?  13 eurocents, comes to around 15 dollarcents per kwh.   is that expensive for US standards ?

no it is meh

I will use usa cents


under 5 very good

5 to 10 mostly of the time good

10 to 15 you enter some zone risky


15 to 20 more risk


over 20 cents pretty high risk


over 30 cents do not mine almost always bad.


My home is 13 usa cents in the winter  make it 10-11 cents due to heating savings

my home is 16 usa cent in the summer make it 18 cent due to warm house in the summer.

I made good money from July 2020 to Sept 2021 with those prices.

But understand July 2020 eth to Sept 2021 eth has been very good very very very good.

I also have access to dirt cheap power so I can move all my in house gear there if market crashes.

If you run 3 cards doing 300 mh =

18 usd a day    burns 20 kwatts or 3.50 usd a day you are up 14.50 usd a day.

but the gear could drop to earning 6 or even 3 a day and you are burning 3.50 usd a day.

I consider you to be okay not terrible not good ok to get the cards if the price is close to retail.

only 12% in we are at -3.78%

Encouraging number if we drift upwards maybe we get to +1 to +3 at worse
Still seems to show lack of a lot of new chips and or new gear coming online.

an s19 at 100th earns $29.61 and burns $8.16 a day or plus $21.35 a day.

an s9 at 12th  earns $3.55 and burns $2.40 a day or plus $1.15.

both numbers are based on 10 cent power.

So s9 gear still works for some home owners.

looking at ebay I see an s9 with psu at 500 or so

and a some s19s around 11-12k

so 21.35/1.15 =18.56

18.56 x 500 = 9280   which means the s19 prices are not that high compared to the s9 if

you are are 10 cent power.

you pay that extra per hash because the s19 will earn well with profits dropping .

So 2021 has been the year of the miner

any established miner keeps turning profits. month after month.

mine on.

I can guarantee you that lost btc address will eventually be subject to forfeit much like an old bank account with no action gets grabbed.

An untouched btc address in terms of no funds ever removed will be considered lost .


The funds will be folded back into mining rewards for blocks.

To anyone that thinks I am wrong I simply laugh.

Zero reason not to do it. Say in 2059 all 2009 address must show some withdrawal or lost.

To those that say no privacy I say you are clueless.

To those that say it will be outvoted maybe in 2059 it will be outvoted but down the road say 2084 or 2109 it will be out voted.

I asked for this to be moved. to alt coin section.

I gave you a merit for your polite reply.

As for should you grab 3x cards if they are full power  for hashing 3080's new in the box with warranty they are an okay buy. assuming the price is not falsely jacked up to crazy numbers.

if they are used with no warranty they are risky.


Also if the gear is going to be mined in California at 40 to 50 cents a kwatt versus New Jersey at 13-16 cents a kwatt they are less attractive.
8685  Bitcoin / Hardware / Re: S19 repeated fan failures on: September 22, 2021, 12:31:41 PM
Sounds like it could be a bad quality fan production batch or a bad quality fan model Bitmain is using for the S19.

That is a possibility. however, I have personally used some very cheap fans on my gears and they don't die anywhere close to the rate OP is talking about, this is likely a combination of bad quality and some other issues.

OP, what is the design of your farm? pressure plays a major role when it comes to the lifespan of these fans, I remember before fixing the pressure in the farm we were losing fans a lot more often than we do now, ever since we controlled the air pressure we seldom lose fans despite the fact that we run most of them at a constant speed of 90% where temps are usually a lot hotter than your temps.

to be clear

your farm should be

intake------- gear------- exhaust

the intake needs to be large enough to balance the exhaust


so 1 s19 has 4 fans then pull about 400 cfm they exhaust about 400 cfm

assuming they are all pointed in correct directions they are balanced in an open space

but

intake fans 1000 cfm >>>>> gear fans 400 cfm >>>>>>> exhaust fans 300 cfm  = bad for fans

intake fans 300 cfm >>>>>gear fans 400 cfm >>>>>>> exhaust fans 1000 cfm = bad for fans

intake  fans none just a small vent >>>> gear fans 400 cfm >>>>> exhaust fans 1000 cfm = bad for fans


intake fans  600 cfm >>>>>> gear fans 400 cfm >>>>> exhaust fans 600 cfm = winner balanced


do check to see all fans are pointed correctly
8686  Bitcoin / Mining / Re: Mining in UAE at max $0.0299/kWh - Nuclear + Solar on: September 22, 2021, 12:13:17 PM
we have smaller scale solar arrays. we have a 110kwatt a 45kwatt and are trying to set up a 500 kwatt array

So you are in a different country different incentives different rules etc.  But you appear to have solid funding and some ability to run mines as of right now. My suggestion is make 5% to 10% solar as a  priority. Mostly to show you are willing to be green.  It allows you into a second set of investors. The ones that are attracted to green clean mining.

Even as I type out this post the  110+45 = 155 kwatt arrays are only 1/3 of our mining the other 2/3 thirds are done with oil/coal/gas.

But we always push the solar as the green alternative. It has attracted some investment money and if we build the .5 mw array it would bring us to about 55% solar vs 33% solar.

If you stay all nuke some will feel you are not green and or progressive for the worlds power problems.

Their thoughts would be "you got a fucking big ass desert and you don't do solar" just nuclear .

You can counter it by having both options and if the people are 'green' mined you can 'give' them the solar site to use. not the nuclear.

It allows you to pivot either way .  And if the solar ends up being a less profitable method you are only in it at 5-10%

If you get more green money expand it to 10-15%

fees are a different matter 15-20% is pretty high.
The initial setup for a mine for a customer can be 15%-20%  but the running of the mine once setup need to be in the 5-10% range.

I e you build a 1,000,000 farm for me your cost . charge me 1,200,000 this = certain profit of 200,000 upfront

then you run it. it earns 10 coins profit your fee to run it = 1 coin

the  profit is a coin

so this is a profit on running it , but price is less certain since coins go up and down
8687  Economy / Service Discussion / Re: is there such a thing as a non-scam cloudmining operation ? on: September 21, 2021, 11:58:35 PM
Are they all just simply scams?   or are there actually some legit ones out there ?

The majority of cloud mining companies are nothing but scam, the rest are overpriced, Viabtc offers a legit cloud mining service, I have not tried it but I use viabtc for mining and they are indeed trusted so it's highly unlikely that such a large pool will turn out to be selling scam mining contracts.

Also, IIRC bitdeer has a partnership with Bitmain which makes them somehow trustworthy, but again, the legit ones are overpriced, the fake ones are just ... fake.

IF they are legit ...    doesnt the "overpricedness" really depend on what the market is going to do ...   or would btc going up not really matter, as you would also me mining less and less, as time goes on, due to difficulty etc ...

how hard do you think btc would have to go up,  to actually make it worth while,   to buy like a 2 year contract now?   what would btc (or eth for that matter,  depending on the contract) have to move to, for it to have been a good decision?

even legit cloudmining company like viabtc has the “we can fuck you whenever we decide clause”

so if you buy a contract you are betting that the contract does not get too good along with betting it does not get to shitty.

you are also betting they do not have a natural disaster.
you are betting power costs don’t shift bigly
you are betting the country that hosues the gear does not shut power off.


all of the above they can use the fuck you anytime we want clause.

so there is far more to the picture then meets the eye.

no one should ever buy a-cloud contract .

I can go further but I wont
8688  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: September 21, 2021, 10:27:49 PM
the spirit of Bitcoin is low these days, the price dump is heavy and people are unsure where this will lead to.

dont worry.

it is at the same place where it was around 30.09.2013.

in about 8 to 12 weeks we will have another great peak in the 200k to 400k area. Sit tight and hodl and look forward for these amazing times to come.

I love believers !
8689  Bitcoin / Mining / Re: You Can't Mine Bitcoin Profitably (Prove me wrong!) on: September 21, 2021, 05:53:07 PM
If I rode correctly,

"After 3 years:

 - ROI of mining - 181%
 - ROI of purchasing BTC - 351%"

what did I do lol
Such a wast of time for me xD  Undecided

and if you purchased coin in april 2021 at 64k you are now down 30%

basically as I said I do not believe any one should compare mining to buy and hodl.  Yet people do over and over and over again.

By the way buying  an s9 for 75 bucks with a psu was doable last summer July 2020.

see how they did if they purchased it and mined and held. they whaled
8690  Economy / Speculation / Re: Always have an exit strategy on: September 21, 2021, 11:18:36 AM
A lot of veterans I talked to back in January/ February had exit plans that were going into action late summer and early to mid fall at the latest. That was a majority of veterans.  I think bitcoins dropping to its new bottom slowly but surely. But it won’t go past ath for a while. It has been nearly a year and 6 months. Historically it probably means the btc 2021 bull run is over.

I think you’re wrong & we are seeing a repeat of the 2013 bull run with a double peak. We will see a really bullish Q4 with multiple ATH’s. Let’s wait & see what happens.

Lets have twin peaks. but fraternal ones. I know these two fraternal Filipino twins.

Good looking girls and fraternal twins 👯

The one that was born second is 5 foot 7

The one that was born first is 5 foot 2

if those ratios hold true for btc the second jump will just crest at 70k

which i would sell at.

but still mine on.

eth would get close to 4800 if it holds forth for eth.

I actually think we are going to have triplets with three peaks.

64k in the spring of 2021
71k in dec of 2021
90k in spring of 2022

could go further  if chips do not keep coming we are still in a worldwide chip shortage which is affecting a lot of shit.
8691  Bitcoin / Mining / Re: You Can't Mine Bitcoin Profitably (Prove me wrong!) on: September 21, 2021, 10:56:59 AM
Excuse my provocative title  Smiley

I am finding that except for a narrow range of BTC price rise, it is better to buy BTC than to mine it.

I have been looking at buying Antminer S19j Pro 100 TH (3250W) from compassmining using their hosting ($.0624/kWH) and F2 pool (1.2%)

It costs 8000 (after 3% credit card fee).

Assuming a starting BTC price of $30,000, with starting difficulty at 1.4363, with both increasing at 4.4% per month:

After 3 years:

 - ROI of mining - 181%
 - ROI of purchasing BTC - 351%

Change the BTC price rising to 6.5% per month, which corresponds to BTC doubling every year:

 - ROI of mining - 337%
 - ROI of purchasing BTC - 806%

If BTC rises only 1% per month, then the ROI of each about the same.

 - ROI of mining - 40%
 - ROI of purchasing BTC - 42%

At less than 1% rise per month, mining does better than purchasing.

So, you can't mine BTC profitably at current miner prices and hosting fees at compassmining.

Prove me wrong!
 


You leave out one big thing.  What if BTC doesn't rise 6.5% a month?  Yes, it jumped up, but what happens when it goes the other way and how does that influence your "buy" model?  Prices rise, prices fall... factor that in please.

if he purchased at 60k a coin he is at 43k a coin today. so buying in april 2021 and hodl til sept 2021 he is off a lot.

oh i likeed your post so i read your other posts ? I gave you enough merits to make next rank.
keep posting away.

about 21-22 to go and still + 3-4%

would like to see bigger price then 43k

the 43k price should keep next jump lower then 3-4%

maybe 1-2

oh bitmain was pushing the s19j at 10000

that dropped to 9300

based on us buyer add the import duty of 2700 you are at 12000

it makes 29 a day so with free power it takes

12000/29= 410 days to roi

simply too much money 💰

price needs to be 7k

that becomes 9100

with free power

9100/29= 313 days

my power is ½ the coins so it would take me  616 days to pay it off. if they offer it at 7k and tax is 2100 total 9100
8693  Alternate cryptocurrencies / Mining (Altcoins) / Re: Any good bang for your buck cards for ether mining? on: September 21, 2021, 10:37:57 AM
the 1080ti evga or mis/corsair hybrid don’t run hot.

In many ways the best card ever made.

we had 28 of them they are closing in on four years old.

We sold off 24 of them to switch to amd 5000 amd 6000 and evga 3000 cards.

every one of those cards still work. used 24/7/1200+ at 165 watts

that is 28 x1200 days or 33600 days not hours of working without fail.

we dust out the radiators once in a while and the radiator fans have had some three maybe four replaced.

they go for 700 or more on ebay. I would sell for less.

these are what the op are looking for. if sold for 600 they earn

3 a day.

so 600/3= 200 days. i am assuming op has cheap power they burn 4kwatts a day if op power is 10 sents the cost to run is 40 cents.

so in 200 days he earns 600  -80 for power he would be at 520 paid back.

roi moves to 235 days not 200

Wow, really fresh statistics on reports. I've been waiting for her for a long time. Thanks, theymos. I wonder if someday there will be general statistics of reporters for the entire life of the forum? It would be interesting to look at this data.

The first place in this rating was not a surprise for me, since I was familiar with the statistics of this user earlier. It seems that he now has the largest number of sent reports, something about 68,000-70,000, an incredible result, there is something to strive for.

Congratulations to all the reporters on this list, all those who contribute to this forum. Maybe it's time for badges?  Smiley

This is from august 2012 to sept 2021 .  I did not do much first year or 2. Then  close to 100 a year from 2014 til now

"You have reported 732 posts with 99% accuracy (712 good, 12 bad, 8 unhandled). Do not worry about your accuracy too much; one accurate report is worth many inaccurate reports."

you could do a volunteer thread. it would get some people to answer maybe you could grab stats for a few hundred vs top 40

it would be lifetime as I think that is what is available to us as non staff.

Any GPUs going cheap because they are unprofitable electricity wise but will run a high hashrate (regardless of watts)?

None

The 1080ti does 40+ mh at 175 watts if setup correctly.

but it is not a cheap card.

I can sell you one at 600
8696  Bitcoin / Mining / Re: Help with revenue calculations on: September 20, 2021, 04:46:04 PM
As I said pm me for info. Basically you want a cheap used miner like an s9 .

you want it to run on firmware that allows it to be fairly quiet .


You want a decent price..

You do not need to know anything but what viabtc pays per th.

they pay 30.52 cents so a s9 set to 10 th earns $3.05 a day

https://www.viabtc.com/ will show you what it pays per th once you open an account

so $3.05 earned and burns about 20kwatts or $2.00 if you have 10 cent power

and about $3.00 if you have 15 cent power.

So a s9 at 300 bucks if you have 10 cent power is an okay deal

an s9 at 250 bucks if you have 15 cent power kind of works.

If your power is over 15 cents  an s9 is not a good choice.

If your power is over 20 cents an s9 is a poor choice.

Good luck in what you pick.

Hey guys!

Im looking for suggestions for cards that are good for their price for mining ETH. Im looking for good price to output efficiency so that I can invest some of my money into a rig and crank some coins while im at school, suggestions?
Good offers don't reach the market Smiley
If you are in the USA, write to the user philipma1957
https://bitcointalk.org/index.php?action=profile;u=64507
Maybe he will offer you something.
You will definitely not be deceived.

I myself am looking for such offers, so I constantly look at various markets where the user is trading used computer hardware. I do not look at shops, in my country prices are like fire.


Occasionally I dump a card at a good price.

@ op I have 4 1080ti hybrid cards.

I'm thinking of buying my first asic, where do you guys buy from? I want to buy a D7 but the official antminer site is out of stock. I found this https://bitmainexpress.com/shop/antminer-d7-1286gh-s-x11-asic-miner/ , has anyone had past experience with this seller as to vouch for them? Don't wanna get scammed
