Bitcoin Forum

I don't understand why others ASIC resistant cryptocurrencies such as Vertcoin and Monero aren't worth mining. At all. It's not worth buying a high-end GPU to mine these coins even for those who don't have to pay for electricity bill. But I do. And it's pretty expensive here (~$0.121) .

I'm about to buy (1) R9 280x HIS R9 280X IceQ Boost Clock 3GB GDDR5 PCI-E DLDVI-I/HDMI/2xMini DP + (1) 750W PSU. I'm confident that I will be able to ROI, but it seems too risky because nothing else is worth mining with it besides Ethereum.

Its a combo of the coin price, mining rewards and difficulty.

It will take a long time to roi if you don't own any preexisting gear already.  The 280x only hashes about 20 mh and if you spent 80 for the psu and 200 for the gpu that's $280, so you are looking at more than 3 months with free electricity.  Which I guess isnt bad but not that long ago you could payoff gpu's in about a month, also difficulty is continuing to rise more with the high value of eth.

you don't need to roi on equipment, only on gpu, equipment are always useful for future upgrade and future mining

everyone here is talking like the mining will die after ethereum, there is nothing more wrong

we will talk about another more profitable coin in 1-2 years, guaranteed...

What about market cap?

How can you be so sure?

because it happened like 3 times already or maybe even more? since 2013 there was always something to mine form time to time, it's not like ethereum was the only coin profitable since altcoin scene went all out

So what? Just because it happened 3 times previously it doesn't mean that it will be the very same thing from now on. I wish I could be that confident.

Its sound like you want a guaranteed investment and its not the way it works.

Its like the stock market, investment is always risky and you can lose everything.

Right now mining ETH is like free money, and who doesn't want free money. Opportunities like this are always short lived.

You can't.....last big profit coin to GPU mine was well over a year ago.It just appears to be a "cycle".

I read up on quite a few altcoins (over 150) over the past several years & thought a few had it in them to go big,but nope......not sure why they didn't.....

Eth is a fluke that actually may move up past or equal to BTC,whoda thunk??  :D

At least GPU's "store" their value in resale  8)

At least until the new gen are released in a few months. Then the resale plummets. Too risky.

Ethereum still worth because

1. Coin price
2. Difficulty

it's still profitable with R9 280 until three month from now

Let's revisit this post after the DAO sale ends.

What was the last GPU you owned?

Got a basement full of 280x and 7970's

Well,my 7970 was bought in 2012 for $325,still worth $100-150 today,after making over $1200 in BTC/Doge/FTC/ETH   8)

6950's did ok,made about $600+ each & resold for $50  8)

Soooo,what's this about resale value ???  ;D

Doesn't look like plummeting to me (smile). I have some 7970's I have been trying to sell but it looks like I can only dream about prices above 100...

Even with new GPU generations out the value does't plummet. Its still worth close to 50% of what you paid.

I had most of the gear and bought a bunch of video cards a month ago, when I started it estimated I would pay my cards off in a month, now it says three. It's a fun hobby but at the rate difficulty is increasing its no big money maker.

This. But the simple fact of having to turn on mining rigs to run for 24 hours every single day is a red light to me. I mean... burned rigs are not so unusual. I'm not necessarily expecting a "get rich fast and free" scheme, but investing in equipments that theoretically can be very lucrative - or a nightmare - if you are disposed (and also able, of course) to discard a big amount of money, which could be better used for some important thing. So yes, I'm expecting a "guaranteed investment" (or at least close to this scenario). Even because I already got screwed in the cryptocurrency world when I went too far by investing in cloud mining. Yeap, that's a dumb thing to do, I know. I learned it the hard way.

I know that ETH is right now good to go. But that's it. The only option actually is Ethereum. Difficulty keeps rising astoundingly fast, so I expect it won't take so much time for it to stop being profitable. At least not for the average Joe, who needs to pay his electric bill, internet provider, etc..

Funny you would have been up 50% if you had just bought coins.

Its a mistake newcomers continue to make. Trying to get theirs but it already gone. Even after warnings from the community veterans.

Buy coins not gear.

ETH algo uses very little power compared to Scrypt/SHA256, it won't burn out your GPU, don't worry.

Exactly: I can't. Since Ethereum Blockchain is being used by the huge IBM and the almost omnipresent Microsoft, I also expect it to achieve a price at least as big as Bitcoin. ;)
Yes, with a GPU you can sell it for a vast market, unlike an ASIC - the own meaning of this abbreviation points the obviousness, Application Specific Integrated Circuits.  :D

Buy only used cards that are still under warranty only with the profits you already gained from mining. Win-win.

GPU warranties don't transfer. But thanks for the advice anyway.

They do with some manufacteurs.

Where I live they do.

Nah, GPUs aren't produced with all that much periodicity and don't lose all that much value. For example, GeForce GTX 970 was produced in September 2014, costing ~$377.60. Now, almost one and a half years later, it costs... ~$354.99.

I failed to mention,I bought mobo's,RAM,CPU's way back in 2011 to mine BTC with GPU's,I still have 6 PCs left from those days.

All was ROI'd way back then,just put em the closet for a rainy day  ;)

Guess what...it's raining  :D  That was about 2 years ago I put em up,they mined alts for abit after BTC went ASIC.

I sold my 5870's,6950's & bought a few 380's,gonna get another 1 or 2 very soon  8)

BTW,DO NOT BUY GPU's ON EBAY.Just get new ones,the chance you take on getting a faulty GPU isn't worth it............I got a few in a row & I'll buy new from now on  :(

Ouch. I was thinking about buying one R9 280x for only 227 dollars + one Corsair Cx 750W for only 116 dollars. I can't find the same graphics card in any other website where I live. This GPU is classified as very quiet, which is something that matters to me. The ROI would be possible, I guess. According to both whattomine and coinwarz, I'm going to get around 60 dollars per month (22 mh/s, 450W, $0.13 kwh), so it means that I'm going to have a ROI only after 5 months and half, approximately (if these calculators don't "fool" me because of the skyrocketing difficulty, as pointed by catlove, lol). But what do you guys think? Will I ever achieve my ROI or not? Or is it safer (and/or better) to just buy ETH and hold them for quite some time until it... adds one more digit to its price, perhaps?  ::)

If in USA buy new from Amazon I am a prime member they have a 30 day return policy pretty much very easy to,and back the card the first 30 days.

They also allow a longer return period during  Black Friday to January 31 st.

Don't know,if the coins will,still be hot this fall but time will tell.

And cards hold value my 3 hd7970"cards have earned more then 400 since apr 2nd.

Ok, but I thought that by putting a GPU in intensive use without stopping even for a second or two could harm the card.

those cycle are here since 2013, so, also anyone with 5 cent electricity or lower, and perhaps up to 10 cent, is mining since 2013, every day and he is making profit, evne in those dead time, especially those with 2-3 cent electricity


beaware about that return policy you can not abuse it, if you do that trick too many times they might close your account

already happened here with some folk that has tried to cheat on amazon

Those calculators are off by quite abit....just mine for a day & go from there,my 7970 & 380 4gig get about 37mh= .35 eth per day approx.

The card I got is VERY quiet,check it out:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202166

And check return policies with Newegg on Ebay,most DO NOT offer returns...beware!!!!

It happened 3 times because it is powered by an ideal that cryptos are meant to be decentralized. And there's no decentralization scheme better than GPU mining right now. And it didn't happen just 3 times but 4 times with ETH..

BTC was once GPU coin
LTC was once GPU coin
DASH and VTC were once GPU coin
and now ETH...

Decentralization is an ideal.. BTC history will always be associated with decentralization IMO there won't be BTC if 2008 crisis didn't happen. 2008 happens because of centralized economy and when in 2009 someone came up with a currency that doesnt need a central bank the idea simply took off. Ideal will never die ..  and that's why the previous poster felt sure.

when you see the same thing happening over and over again, you can't simply ignore that fact, and still believing that going against that trend is the right thing to do

it's all about probability, nothing is certain, but if the probability tell me that it will happen again(higher % than not happening) because of the past, then i follow that route

Ok, thank you for your explanation. Which is the best GPU? http://www.sapphiretech.com/productdetial.asp?pid=C4D1B443-6105-4A63-85DE-1732CC9C443D&lang=eng ($210,67) or this one http://www.hisdigital.com/un/product2-786.shtml ($224,72)?

The AMD R9 390 8 GB is the best for Ethereum mining. I use the XFX cards with back plate. They are very steady.

But which one should I pick between those two cards? R9 390 8 GB is too expensive.

Yeah its expensive but i think its profitable if you mine ethereum for now and i dont think if its profitable in few months because the difficulty is increasing month by month..

What does this "few months" mean? 8 months? Also, which one should I choose b/w those two GPUs (supposing it's safe to assume that there will be more profitable coins to gpu mine after ETH stops being profitable, of course)? Forget the R9 390. I won't risk all that money, because I'm VERY poor.

You are kinda right (because you can't say for sure that in 1 or 2 years there will be another profitable coin to mine with my GPU). Since it's expected with all this "certainty" to find profitable coins to mine with a GPU over and over again, I think I'm going to accept the risk behind all this mining thing. I think it will be my last bet in this "cryptospeculation" mess. I remember when you told me that Bitcoin is the only coin to trust some months ago, though.

all i need is a gpu to gety going i have everything else now

When I was mining Bitcoin with my previously owned S1 I was getting exactly around what was estimated in Coinwarz.

Please, just tell me fast which is the best GPU? http://www.sapphiretech.com/productdetial.asp?pid=C4D1B443-6105-4A63-85DE-1732CC9C443D&lang=eng ($210,67) or this one http://www.hisdigital.com/un/product2-786.shtml ($224,72)? I'm afraid to lose this opportunity, because there aren't a lot of R9 280x and this HIS card seems to be one of the quietest R9 280x cards (if not the quietest).

Sapphire is to AMD what EVGA is to Nvidia so I'd go with Sapphire...
How is the warranty like where you live ? Go with whoever gives you the longest

These cards are both used, so I will have only 3 months after my purchase. HIS card has 384 Bits, while SAPPHIRE has only 256 Bits (but I don't think that it will matter in my hashrates). Please see the difference and tell me which one is a best buy:
http://www.sapphiretech.com/productdetial.asp?pid=C4D1B443-6105-4A63-85DE-1732CC9C443D&lang=eng
http://www.hisdigital.com/un/product2-786.shtml  

Eth is NOT bitcoin......the hashrate fluctuation is extreme,for whatever reason,like a roller coaster.I've noticed on my pool my hashrate goes as high as 48mh & the next minute it's 17mh...... ::)

That's why those calcs are off  ;)

If they are both used they are too expensive. You can get a 380 for that price.

Go on Craigslist and get some second hand 7950-7970 instead.

The "bits" don't matter,the AMOUNT of RAM matters.

You want at least 3gig of RAM on your vid cards,4gig is even better,the DAG is growing & 3gig may not be enough in the near future(or far future).

Now that's a golden information! So how can I measure if I will ROI or not with Ethereum?

Do you think I'm from the USA? I'm from Brazil. There is a shortage of these cards (R9 280x). Especially used.

Yeap, I was almost sure that the "Bits" thing has nothing to do with the amount of hashrate my GPU will achieve. But I didn't know I must aim for a 4 GB card instead... that's a lot!!

What is the cost of living in Brazil? Is rent around $100USD per month or so?

Food $20USD per month?

If so you can get rich very quickly with that one 280X.

A rent for only $100? Yes, they are at least ~$100, although the average price is... $469,69 ($9.06/m²)!! I don't think you will find one for such low price in big cities. Perhaps in a favela?  :-\
By the way, what is the average price, in m², in the USA (I'm supposing you are from this country)? Food here costs ~$106,74 for each person ("cesta básica" - basic food basket, if that's how it's known in the United States). Nobody can get rich quickly with a single 280x, regardless of the country s/he lives in. That's nonsense.     

Is there problem with getting gifts in the mail?? Like if I were to buy a card for you,with your money of course & ship/mail it to you could you get in trouble?? Just a thought  ;)

Most apartments are about $600-1000 a month,food for 1 person can be about $150-300 a month (being very conservative with those costs).

I have rented single wide trailers for $450 a month though   ;D

OMG, I just clicked in "buy now" in both a 850W PSU and a R9 280x! I'm deeply uncomfortable!!!

I would have to pay A LOT in import fees. In fact, Brazil has one of the most expensive import fees in the world, afaik. Also, it would take > 15 days for the shipping time, which would affect my ROI, obviously.

Well,that sucks,I'd be willing to help but it would be fruitless your saying.Very sad to hear this  :'(  I'll be in Costa Rica in about 6 months if things go right,maybe meet & have a fantastic meal??  8)

Yeah I heard about that. iPhones are the most expensive in Brazil actually due to the import cost. I think they cost exactly double from US prices.

Ethereum isn't the only GPU-mineable coin that can be profitable right now - it's just probably the MOST profitable, and pretty much profitable even if you have average-to-high electric rates at this point.

 X11 (Dash) is still GPU mineable, there hasn't been enough ASIC deployment to noticeably affect the hash rate.
 YET.
 But that looks likely to change this summer.

 There are other coins that can be GPU mined for a profit if you have cheap to VERY VERY cheap electric, but cryptocoin mining has always had a "cost of electric" factor to it's profitability.


 8GB cards are overkill for Ethereum mining, though if you plan to have other uses for the card later the extra memory might be useful.
 Based on DAG file size growth rate and probable timeframe of Ethereum converting to PoS from PoW, it's uncertain if a 4GB card would be overkill (3GB will almost definitely be needed late this year or early next year, I forget the exact timeframe, if Ethereum stays profitable to mine).


 IMO avoid HIS fan-cooled cards, they tend to use VERY CHEAP fans that die way too young. Their Ice-Q BLOWER models seem to use good blowers though.


 Rents in the US vary a lot - but the average if you avoid HIGH RENT areas like Southern California or the New York megaplex seems to be in the ballpark of $10-15/m(squared).
 Where I live right now is at the low end of that range, but it's a fairly low cost-of-living area - apartments for $500 are easy to find, most around here are less than that for
 1-2 bedroom places.
 Most folks in the US don't speak Metric very well if at all, US is still on the old "imperial" measurements system with feet, miles, and such with some exceptions.

 Food - varies. I eat pretty comfortably on $190/month but a lot of that is Diet Pepsi consumption - drop the soda and I could get down to more like $100-$120 range.
 I have pretty simple tastes though.

possible : yes
probable : I tend to agree
guaranteed : lol
This happened with litcoin, then dodge (less than the others at least in amount of time) then ethereum (probably more than the others two combined). Three time (after bitcoin : I count only coins which have been able to provide profitable mining for a large amount of miners and a significant period) : do you think it is enough to be so sure it will happen again?

yes because i don't look specifically at a single coin, i look at the whole time frame where there was profitability, and late-2013-end summer of 2014, blow out of the water the current time frame for etehreum porfitabilitym, by a long shot

yes instamining does count, if you like it or not it's always profit, and yes now it's not possible anymore, but from time to time some good early mined coin show up and give you enormous profit

Are you sure that X11 (Dash) is actually worth mining?? Both coinwarz and whattomine tells it is not. According to whattomine, with one R9 280x (~6.4 Mh/s, with my computer consuming ~450W and $0.13 kWh) I would get ~$1.13 per day... IN DEBTS!! And so is with any other coin mineable with a GPU, except ETH... for now! Or aren't these calcs able to estimate correctly even for these coins?

I just bought a HIS R9 280x (see above if you want to know the technical specs of this graphics card), so I hope you are wrong.  :-\

I forgot that the metric system used in the USA is different. My bad. In fact, USA is exception among practically every single country, lol: https://upload.wikimedia.org/wikipedia/commons/thumb/a/ab/Metric_system_adoption_map.svg/2000px-Metric_system_adoption_map.svg.png

You drink too much soda, by the way! Why don't you opt for drinking juice instead?

Yes! Why not?  8)

you can reach 11 mega with the 280 and also that wattage you mentioned is too high, a single 280x can consume 200 if undervolted, still x11 is not profitable unless you have 5 cent electricity or lower

The main problem is not the high import costs (although it matters for products/commodities brought internationally, obviously). It's the low purchasing power, high cost of living, high inflation, economical/political crisis and so on... practically everything here is damn too expensive, regardless of being produced here or not.

11 Mh? Ok, I have no clue if that's NOT possible. 200W? Yes, my GPU should need less than 300W without needing to underclock it - but what about all the other components, such as MOBO, HDD, network card, etc..?

it's possible but you need the last sgminer and a specific drivers not the last one, regarding wattage, other component do not consume much

Hm, that's great... But STILL, even if it were amazingly possible to have a rig running for 200W (that's the average consumption of a computer with a low-end GPU included in this math - http://www.tomshardware.com/reviews/radeon-r9-280x-r9-270x-r7-260x,3635-18.html), I would just have to pay more for the power bill, instead of "profiting" at least pennies. As you said, unless I paid ~5 cents of electricity, there is no way to profit from this crappy coin.

Two R9 280x needs a 1000W PSU for a good reason - https://www.youtube.com/watch?v=DUvUmo8dBmU

You gotta put something in (power costs) to get something out.My power is 13kwh,I make .30-.35 eth per day,I barely see my bill rise with 350 watts or so.Making $4.50 per day at current rates of $12.63.
That's why I didn't go with the biggest vid card,380's are quiet & efficient  8)

Now when I had my 2 S3+ mining at 750-800 watts,I noticed obvisously,but the earnings were barely pennies per day,not $$$$$ per day  :D

 0.13 is a rather HIGH electric rate - THAT is what is killing your profitability on most coins, it's almost DOUBLE my non-Summer rate.

 For me, Dash specifically is profitable - but it's not by a LOT, electric does eat enough that the power company profits more than I do where I'm at currently.

i'm paying 0.28 cent and i have profit, so you can have profit unless you are paying more than 0.35...

your gpu is outdated, it's better to buy 390, nano or 970, or also 380, all the other are not a good option right now

The quickest ROI card is the R9 390 considering the whole system cost. That can be achieved by undervolting.

i don't agree 970 is equal in power, just buy them used, they are sold for $250 or lower here, and within two week, you may find them at $200 already due to 1070 release

mine hash at 147w/22MH, g1 gaming, reference or msi would be even lower, g1 gaming is power hungry

In my place, the 970 and 390 cost the same. So for me, it is better to buy the 390. It also has 8GB memory.

If the Ethereum last more than 2 years, we might need big memory size to minimize the hash rate decrease.

High profitability for mass miners has been for short windows periods only.
Of course more clever miners, targeting carefully chosen coins at launch or when unknown from the masses and carefully selling the earned coins at right times have been highly profitable for most of the time : but this is not for the big masses of miners and it requires investing a lot of time.

Moreover, the past is not enough to predict the future.
Investing in mining always present some risk.

That is right. That is the reason why I mine with 8 GB and 4 GB cards. I have 280x, but they are hashing less and less.

yeah i dumped around 30 280x on ebay last week $200 per card or so not bad considering oi bought them about a year ago for $220 a card and have mined thousands of eth with them over the last year.

Are you buying the 490 or other high end cards?

Ethereum will not last 2 years.  I am pretty sure that it will go POS before the 2GB cards can't mine anymore. Buying GPUs with 4 or 8GB is a waste of money.

Even if it doesn't go POS, then the difficulty will be too high for any decent profits.

No its not worth X11 mining anymore because ASIC are out.

Before ETH you could mine X11 and make about $0.30/day (on free electricity).

There is also Qubit and Quark but those also made about $0.20-$0.40/day (on free electricity), so unless you have free power, you won't be able to GPU mine anything.

Buying Nanos since they use like half the power or less even

24.6 mhs for 100 watts on a nano vs 20mhs and 220 watts for a 280x   no brainer for me, my farm will be smaller but cooler and more efficent, also the nanos seem to be able to run for days withnoute reboots or anything

one 6 gpu nano rig has been running for two weeks never had to do anything to it, some of my 280x rigs are flakey and i need to reboot them daily.

Same thing goes for the 390s they run for days with no issues but they pull like 260 watts using claymore  and generate a ton of heat, im dumping those too

 It's due to go POS sometime next year. Looks a bit marginal for anythign past ONE year at this point, and the DAG size growth is guarenteed to keep eroding hashrate.


 X11 ASIC have been seen - but in TINY quantities that appear to have had no noticeable difference on the network hashrate. That SHOULD change soon, but it's not happened YET.


 Only 2Gig cards I have (and am mining with) were either already on hand (my NVidia stuff and some leftovers from Litecoin/X11 mining days), one VERY cheap HD7870 that's well on the way to paying for itself, and a couple of GTX 750ti small form factor cards I was going to get for the machines they are going into anyway eventually.
 I doubt I'll bother with any more 2Gig cards - I've pretty much filled up every open PCI-E slot I had available (living situation RIGHT NOW precludes going open-case and risers, that should change after I move this summer) so even cheap used stuff is about out of attractiveness for now.

buying nano right now, is a bit stupid, too much in cost, you will pay upfront your electricity

better wait for new amd, so the nano price will be discounted heavily, i'm also sure that the new polaris or vega will match the nano in MH/w

Nano is good option for long term vision and you can resell in the future better then other cheap cards.

so after paycoin, etherum we will see new altcoin worthed to mining with VGA ?

Paycoin is not comparable to ethereum : ethereum offer a huge amount of btc equivalent to mining daily for a long period thanks to the sustained volume and price.
In the future zcash has probably the potential to offer a good gpu mining period.
https://z.cash/blog/why-equihash.html

It depends on the mining efficiency of the new AMD cards, if they are not so good, it is better to use Nano now.

You guys think we can use Rx 480 with the current mining softwares ?

RX480 looks interesting, if only due to the HUGE memory bandwidth increase - which *hopefully* would translate to good Ethereum mining hashrate.

 Availability is going to be an issue - NVidia is already having availability issues with the GTX 1080, a "mainstream" card like the RX 480 is likely to have even worse such issue....

RX480 has only 256 bit memory bus, that is slower than the 512 bit from the 390. The memory frequency could be higher.

I don't know anything about Eth. mining. Can a asic scrypt miner mine Eth?

No, gpu only.

Ask the R3 consortium

 NO.

 An ASIC can only mine the specific algorythm (or algorythmS in the case of the Gridseed/SFARDS dual-algorythm chips) it was made for.

 RX 480 is listed as appx. 8/5 of the memory speed of the R9 390, as I recall.
 Should make up partly for the narrower memory bus, but probably not entirely.

 It's not really AIMED at being an R9 390 replacement though for most usage - more of a R9 280/280x/380/380x range card with some pretensions of arguing with an R9 290/390 on stuff that isn't memory-limited (It'll probably be faster on RC5-72 work than my 290s, but that's a rare "don't care at all about the memory" extreme example).


 It's still GCN supporting OpenCL, should work with current software once the drivers are updated to support the card - might not be "optimised" but should still work.

For the Etheruem  mining, I will not buy the RX480 if the performance is less than 390, even it consumes less power.

the real 390 competitor it's vega, the 490, not the 480, but since gpu do not scale in the right way with etheruem, i would not hold much hope for the 490 being the best card to get

The Vega was originally to be launched early next year, but that has been put forward. If there is big improvement over the 390, I might buy it.

It has HBM2, very wide bandwidth. It could be faster than the R9 390. But the price could be very high.

The price of the nVidia 1080 is about $900 at the moment. When the Vega comes out, it would be the similar price.

If you choose nvidia its worth of high amount than choosing amd.. better to buy amd its cheap price than intel nvidia.

I shall wait until the end of this month to see the performance of the AMD RX 480. If it is good, I might buy some.

 The Nano/Fury line also have very wide bandwidth HBM, yet they mine SLOWER than my 2 generation old R9 290 cards do.

 There's more to the issue than just wide bandwidth.

The PoW algorithm requires more random access of the memory, so the latency is more important than the bandwidth.

The price of Etheruem dropped a lot recently, the difficulty also rises fast. It might not be so profitable to mine in the future.

that is your opinion. But some miners do not agree. They are adding more hashing power to the network now.

The miners ordered the graphics cards and other components before the drop, they had to assemble the mine any way.

It seems they did not return. So it seems that they are the believers of the Ethereum and think they can make profit by mining.

The network hashing is around 4250 GH/s at the moment. So the miners are still building new rigs.

The difficulty is rising and the price is dropping. So maybe in two months time, it will be not profitable to mine.

It will only get worse since Antminers won't be profitable anymore and people will buy GPUs instead.

those are chinese or someone else with 0.05 electricity, remember that those folks can keep mining until everything is dead basically

In theory I will mine 22 eth coins in the next month making about 220 usd  my power at 18 cents summer rate will be 110

thus a 110 profit.  eth coin will get a new price pump from both nvidia and from amd as both companies can buy eth coins to pump price as a form of advertising .


every new rig

psu       = so all psu ,companies, seasonic ,corsair, rosewill, thermaltake, silverstone, evga
cpu       =  intel + amd,
gpu       =  nvidia + amd
hdd/ssd = drive builders Seagate western digital samsung sandisk
ram       = ram builders  micron samsung hynix

so all of the above make money if eth coin sticks around.  and that list is incomplete.

I see an eth coin price rally coming.

If you feel a rally is coming it's better just to buy coins. Looking pretty grim right now though.

do you think gpu mining has that much of an impact in the bigger custom build pc game?

what percentage of newly built rigs with new parts are for miners do you think? cards are always replaced of course but the rest of the rig?

myself, i just reused an old core 2 rig from my btc gpu days for 2 cards, plus stuck one card in my daily driver to take advantage of games and the fact its on 24/7 anyway. but of course im just a "hobby" miner in it for fun, not like you and others having, well, even more fun :)

The difficulty of the Ethereum mining is rising very fast. It means there are many farms, They could be unprofitable after the price drop.

The difficulty now is similar to 4 days ago. It seems the hashing rate rise is having a pause at the moment.

The difficulty level is rising again. It is a new all time high. So the Ethereum mining community is very confident.

I heard the SIAcoin is most profitable to mine at the moment. But the Etheruem difficulty  is still rising.

Reason why I am buying ETH and mining as well.

You can see that every time the DAG-file changes (every 1-2 weeks). All rigs need to download the new file then (1.5 GB) and some Rigs won't update automatically. So they need to get a little kick (deleting old files, downloading new ones, restart the miner software). The pool hashrate loses almost 20% for hours and of course, the difficulty is adjusting then.

The 1.6 GB DAG file is not downloaded from the internet. It is generated locally and transferred to the GPU.

The Ethereum is quite profitable to mine. I heard that many bitcoin users are buying the Ethereum now, so the price is high.

When the Ethereum price is high, people will mine it to make some profits. Miners will chase the most profitable coin.

Miners are also mining other profitable coins such as Feathercoin, Vertcoin, Siacoin and Decred, anything profitable.

Miners are mainly mining the Ethereum as that one has the biggest market cap and there are more buying.

The combined Ethereum has over 4500 GH/s. That is a huge amount of hashing. Hundreds of million are involved.

The combined Ethereum has over 4850 GH/s. So that is an all time high. I do not under why miners invested so much.

There are several reasons. One is that the miners are very confident the the Etherum price will rise, and they have very cheap electricity price.

My electricity is too high. If the difficulty rises another 50%, there will be no profit at all. So I will not expand.

The combined difficulty or the hash rate of ETC+ETH has reached all time high. And there are shortages of 4x0 cards. So somebody is expanding fast.

I think the new miners are based in the cheap electricity prices. The electricity in West Europe and some parts of America is too expensive.

If the Ethereum difficulty rise another 20% and the price does not rise, I have to switch off my Eth mining.

The difficulty of the Ethereum has dropped a bit in the last few days. I think it will be more profitable to mine now.

Right now XMR is very profitable. At some point is more profitable de ETH or ETC. Hoping that XMR will be MOONero, I think you can give it a try to mine XMR.

Good luck,

Yeah difficulty doubled in like 3 months and it goes down 5 % and everyone is saying its profitable again.

That is because Ethereum miner moved to mine the Monero. When the price of Monero drops, miners will move back and it become less profitable again.

I think the miners are moving back and forth between the Monero, ETH or ETC. Especially the ETC and ETH.

Today, even the ETH alone has a hash rate of 5700 GH/s. It seems the miners are very confident the price will rise.

It's not profitable at all. I mine it using claymore's miner while dual mining, but just mining Sia alone is a waste. 1000 Sias are worth 0.52cts currently...at 1.4Gh/s, it takes me 2-3 days to round up 5000 of those, def not worth it, only if you have free electricity maybe.

However, once Sia get their software a bit more user-friendly and do some more advertising, they could become the new dropbox and be worth a lot more than now. I personnaly keep my Sias for the time being.

You are right. With the increase of the difficulty in the past month, if the trend continues, it will not be profitable soon.

It does not matter too much. We will have the ZCash to mine in the next 5 days. That could make somebody rich.

Maybe if some of the massive farms can instamine some blocks, but the dev team at Zcash is taking steps to minimize that as much as possible.

The 3 leaders in profit will be Zcash, Etc/Eth and I think it is probably best at this point anyway to let the corporate outfits fight over Zcash mining.  That will mean hash rate reductions in etc/eth.  It is also likely this massive amount of GPU's added over the past month were for the mining of Zcash so that is essentially 75'000 GPU's ready to hammer Zcash and possible even more if the coin sells for a large amount.

Just remember to cash out all your coins before then in case eth/etc price dumps to buy up Zcash coins.

I agree with that. The Ethereum price is dropping now. It might be due to the fact that people are selling to get bitocin to buy ZCash.

The Ethereum price dropped a lot in the last few days. It seems if your electricity price is high and have old cards, it is not profitable.

I like rotisserie chicken but I can but one small one for $5-8. If I am going to spend $250 on a nice rotisserie. The math works out to me having to eat rotisserie chicken a few times a week for a vary long time to make it make sense to buy the rotisserie.

My point is for the investment to get started. And the cost to run the machine none stop for .32 daily of a $8 crypto coin. I feel like if I really believe in the coin I should just buy a few a week.

I wish I did not miss the boat with mining. It was like a modern day gold rush.
