2201  Bitcoin / Mining speculation / Re: What is a good setup with an investment of $5000 - cheap electricity- on: November 18, 2015, 09:11:50 AM
Personally i would go for safety and buy some server PSU with half of the money invested to S5 and half for S7 asics.

Buying old gear (S2,S3,S4) makes no sense. First of all the effiency and secondly the guarantee, For hw long will they work...

Actually buying S7 with actual cheap~near free electricity is a bad investment, the ROI takes a very long time 8months+ versus S3~S4 that take 2-3 months, S5 that take 3-4months.

Beside the S7 that was sniped from Bitmain when the price collapse at 4BTC, they are a pretty bad investment.

wait, how is the s5 taking 3-4 if in one months you do $90 only, and with 0.05 electricity which is cheap enough, you pay already $21 so only 70 net in profit

1 s5 cost more than 300(350) this mean 5 months, used can be another story, but so is the case for s7

1300GH/s is 100$ and that means 3 months or so. Yes used, i'm not sure where you can get S5 brand new? Wink

Also 0.05$/kWh is just one value, its not the cheapest available, but its a good cost to mine at. If you pay 0.05$ ROI should be 4months or a bit less. If it take longer, you probably overpaid.

hi guys, i am new in bitcoin world, I interested in mining but some reasons i can't start easily. My best option is cloud mining i am currently registered in www.hashnest.com but i did not yet investing. can anyone try this website?

I'm afraid to be a victim of scam.

please share your knowledge about that website i plan to mine.

or anybody can offer the best cloud mining website.

thank you guys.

Good luck with cloudmining!

Hashnest is actually one of the rare legit cloudmining companies, at least up to now. I suggest that you do more research about cloudmining. I see that you are new and you should be aware that even with legit cloudmining services, it is quite hard to ROI!

Personally, I don't like cloudmining and I would stay away from it. Especially with the upcoming halving. There are just too many uncertainties!

Yes, not being a scam does not mean they aren't going to get your money. They will, trust me, just not by scamming you. The hosting fee is way too high, so you're looking at long, marginal ROI. The service is there to make them money, not make you money.

Look like RichBC's guess did not come to be.


Tough game this guessing.  Smiley Then again who would have guessed that we would have 4 different Default Frequencies / TH/s and 2 different chip count S7 in such a short period of time?

Still they are running out of permutations, unless we start seeing different Default Frequency 135 Chip versions.  Smiley


Rich

I would really like to see a two board S7 with a high chip permutation, with bigger heatsink, should make the thing very quiet during winter and make it cheaper to buy it single unit by single unit.

Back to wishing for a 3.5TH~ "lite" for Christmas.

Yes I guess we have several games... Guessing what they might do, guessing what it is while we wait for someone to get one, and Wishing for what we actually want.  Smiley

On the Wishing front yes I still think that a 2 Board S7 would be a great product. I am actually now torn between wishing it would be based on 54 or 45 chips / board? 45 chip I feel would be a very solid product with a lot of scope for over & under clocking and volting. Whereas 54 chips / board would push up the hash rate and I think respond well to overvolting which is much easier to do with a Server PSU than undervolting. Unfortunately I don't expect to see either...

Am still intrigued to find out why they have found it necessary to have so many variants? I can only assume that they are getting a very broad spread of BM1395 chips and this is there way of coping with this? As has been said already it's going to be a nightmare in the 2nd hand market to know what you are buying.

Rich


Maybe they are dealing with different fabricant that can do one but not the other? Its nagging me, as to why they are doing this, as i can't come up with a reason. Sure they have lots of BM1385's but that doesn't really justify doing random things with them?

I would look at difficulty change recently aswell.  It's scary to see a possible 10 percent change in this day/age I thought we were past 10 jumps. But it's not looking good.

So when you do your ROI OP I would use some big numbers on possible ROI just to see what it will look like if it stay's bad.  I'm hoping this is just Avalon and Bitmain and will end soon... but i'm afraid the competition with a little higher priced BTC will bring a lot more hash our way.

Indeed, i am using 5% increment at the moment, which is still scary. Hard to believe that 40 PH/s suddenly went online, i don't thing it could come from S7's or SP50 so soon or similar. There were those 1PH/s cargo container being shown around last month. Maybe a "batch" of those made it online?

It really make the ROI of S7's bleak if it continue this way.

I don't think 10% is sustainable, but its still scary to see it, even if its just once.

It seems that my forecast was wrong.  Smiley  Batch 7 is another variation with 162 Chips, 5.06TH, 1270W, Default Frequency 625MHz, 0.25J/GH and Supply Voltage 12.0V+5%, should not be less than 12.0V

https://www.bitmaintech.com/productDetail.htm?pid=0002015111710183627718X85SYG0616

I can only guess that they are selecting BM1385 for these?


Rich

Interesting they have a new batch.  It's almost like pre-ording you order so far ahead.  1.5 Month lead time to get product is a change in bitmain.  It is intersting as i would guess with 1.5 month lead time they could order all parts, etc from customers money not even need to use their own like when batches were made close to shipping date.

I really hope they push timeframe to less day's ahead when they look at more batches.

I suppose it give them more operational leeway, i'm guessing they realized that people trust them enough that they can get away with doing this, as it give them another edge. Interesting of them to make a step up in chips instead of down. Look like RichBC's guess did not come to be.

Sound a bit risky to buy in now, as with the difficulty increase, i'm not sure this unit will be worth 5BTC in 3~4 difficulty rounds.
2208  Economy / Computer hardware / Re: [WTS] BFL Monarch SHA-256 Mining Cards on: November 17, 2015, 08:42:10 PM
I don't want to be too much of a spoiler here but you will probably need to come down on pricing if you want to sell, or try ebay or craigslist for better results. Almost everyone here on this forum is trying to make a buck off someone else. Everyone does ROI calculators, and it is hard getting power for free nowadays. Everyone wants more of their money. It is capitalism.

0.35 cents per GH here for monarchs (1.4GH/watt)

0.17 cents per GH on another thread for SP20s (1.5GH/watt)
0.40 cents per GH on s7's someone has (4GH/w)
0.36 cents per GH on some s5's (1.9GH/w)

In all fairness the power supply price is pretty on par with amazon and newegg.

I fully see what you mean, but others would clearly see, this is the best you'll get with the amount of ready to ship products I have. Sure you can get a couple SP20s for 0.17 C/GH but can you get 6? 10? 20 of them? I have a lot of monarchs here and 0.35 per GH is more than sparing for those that want a big amount. But I fully get the society here on this particular sub-forum. It gets this nasty on almost all forum marketplaces. But this thread exists for everyone that isn't a "get an S7, done" type of human.

To be fair, the answer is yes, the price is so high you can get bulk purchase from expensive resellers at that price range, or even cheaper. For example you can get S3's for 180$, which would be a much better deal and you can get tons of them. And the retailer is in Canada too. They even drop their price to 200CAD every other month per S3's.

At that $/GH their overpriced S5's would be about the same $/GH, but better efficiency.

Still, you're the one selling the hardware, not us, so what we think does not matter, if you can find a buyer anyways.



Antminer S3 for $180? That's expensive.

Yes it is, which is my point. You can buy them in bulk at 125-180$, since at that price... Well you get it anyways. Imo still a better deal than this.

Now like I said, i'm not totally ruling out anyone that wants it for a cheaper price. Honestly i'm trying to satisfy a bulk order before I go selling them individually. Notice how you won't see people selling monarchs or in this volume for that matter. Regardless of the statistics, they are well designed, sustainable machines with literally no maintenance required (unlike every single bitmain product, every single KnC product, and every single GaW product. I have at least two of almost everything, and BFL tops in design, stability (though the company has shafted all it's customers, the product itself is exact.)).

Now if you guys want a lower price, buy more than just 2 units. Otherwise, I just lose money rather than just keeping them and start mining with them. I don't *need* to make a profit of the sale of these monarchs as this bulk order for me opened up my line of communication with some other ventures, but I sure as hell want to stay away from a loss. Neutral is fine by me.

If you guys want some, let me know how much (if its over two, AND is a multiple of two). I only want to sell these in twos because otherwise it would make this really awkward (with the way BFL designed these things).

Whats the problem with Bitmain products? I have bunch of AntMiners and the only maintenance i've done this year is blow some pressured air through the fan/heatsink once in a blue moon. But for risk of going off on a tangent, i'll agree to disagree. I just think most buyers here are picky and won't take a deal if the price is more expensive than bulk reseller and even ebay. (For different products, same efficiency, better $/GHs)

Agreed with GAW and KnC. Specially GAW which had no actual product of their own. Just rebranded Zeus.

I got my hand on a 1.9, was surprised since it take over 393.75 freq effectively, running 400hz at 1.32+ TH/s with virtually no HWE, all the others cap at 393.75hz at 1.29-1.3~.

SMD's aren't that bad. We'll see if this board is a 1.9 or 1.91 and see what happens from there. Maybe we'll have another project on this thread.

just updated first post

What kind of PSU are you using?  Are you using all 4 PCIe cables to power it up as well?  Is this a new(used) unit to you or did this just start happening?

Also, do you have pools defined on MRR?  You need to have a pool defined in the webui there otherwise your miner won't hash through them.  I don't know if it would fail over to your third pool, kano.is, because I haven't tried that.

this is one of the last of 20 s5's tested same psu (lepa 1600) and config
so there should be no problem from those things

Pool info seem to be correct, since they read as alive. You could still try different pools but anyways;

Swap one board into a working S5. If it still read dead, then test with the other board to be certain but it sound like it could be possible that both board are dead.

Hi, I am running BFGMiner on my iMac and it says I am getting 0.00Mh/s, how can I fix this? Sorry, I am new to BitCoins. Also on my pool it says that my worker is offline.

Pretty sure BFG is looking for a miner, detect none and thus list no miner and a speed of 0.

Which mean you have no miner on your computer and you can't actually mine Bitcoin with computer anymore, especially not a mac.
2214  Bitcoin / Mining support / Re: Cannot Access Antminer S1 Management Page Over Wifi on: November 16, 2015, 11:58:41 PM
The problem is that with both WAN and WWAN on the same subnet the S1 can receive packets on the WWAN interface but replies on the WAN interface so wifi access only work with the Ethernet cable plugged in.

Quick fix is to connect via cable and move the WAN interface to a different subnet

(e.g. IP - 192.168.2.42
Subnet - 255.255.255.0
Gateway - 192.168.2.1)

If it doesn't work you will need to give your PC a static IP address on the 192.168.2.0/24 subnet to get back into the S1 to fix things.

Wow, how complicated. I just setup mine to DHCP, turn on its wifi, unplugged Ethernet and done. Went and gave it a static DHCP lease later for good measure. Running two subnet sound like a pain.
2215  Bitcoin / Mining speculation / Re: What is a good setup with an investment of $5000 - cheap electricity- on: November 16, 2015, 02:48:43 PM
With 5k and cheap electricity better you buy 2 s7 and the rest you buy s3. Tongue

With 2 s7 you can get 1.85969600BTC/month and get Roi in 8 months if bitcoin in today rate. Tongue


Thanks man. but im still trying to figure out if i got the math right on Cost per KWH.

My usage is 1432 and my bill was 127.88

so  127.88/1432=.0893   so thats my KWH right?

and if so is that still decent to make a reasonable profit monthly?


yeah 0.09 per kwh would be a reasonable rate, not really low, but average.  Dont forget you can sell your miners after a while, so factor that in your ROI.

That's actually pretty expensive, 0.04$/kWh in East Canada (also free cooling 8 months a year), would get better profitability hosting hardware in a datacenter than pay 0.09+ per kWh. Just a thought.

Its hard to say what will be profitable right now, we're looking at a huge difficulty jump this round, if that keep up, not much will remain profitable at 0.1~ for very long.

Hi,

I'm planning a trip to Canada and possibly New York before the end of the year and since I'm moving back to New Zealand I want to pick up a couple rigs before moving back to the middle of nowhere.

Planning to be in Toronto in December.

Cheers,
thebonenz

Bitcoinware is a shop located in Toronto, i was told previously, by them, you can go and see them/do local pickup. http://bitcoinware.net/

The big caveat is their price is ridiculously high.

That website never has any good deals. They even sell very old gear are ridiculously high prices.



I live in toronto and wouldn't deal with these guys i emailed them a couple times and they are super sketch, so word of warning.

Same, had pretty bad dealing with them, they replaced stuff i bought with cheaper version watt meter(a Rosewill instead of a P3) and refused to refund the difference.

After one month of complaining i said "i give up, enjoy the red trust on Bitcointalk on their chat" and suddenly few hours later they contacted me saying they would make an exception and "Price match" the crap they sold me to the price you can get it anywhere else.

2219  Bitcoin / Mining speculation / Re: What is a good setup with an investment of $5000 - cheap electricity- on: November 15, 2015, 08:36:46 AM
I am not new to Bitcoin. I have a healthy knowledge of Bitcoin as a whole. I even dabbled in altcoin mining with some GPU's. So i have a general conception on Bitcoin mining. But i get many different points of views as to mining on a small scale. So I just wanted to post the question of my situation and see if maybe your reply's will have some consistent answers. Reading the forums for a few years now i see that some smart and experienced people could have some guidance to point me in the right direction.

I currently live where my power is around $4.30 to $4.80. I have an investment capital of around $5000 that was a no interest loan from my folks that i will be making very small monthly payments on. So ROI is tricky to factor in. And to be honest I'm looking at it as free money as the payments are so small and hell there my folks. They might one day say nothing more is owed. So ROI is not an issue.

What i am asking for is opinions on what is the best coarse of action to get me up and running with a solid operation and maybe getting ahead of the curve a little as far as hardware. Not wanting to leap forward to fall back with equipment that will become obsolete as soon as i plug it in. Or if going many but smaller less powerful is the way to go.

My goal is to keep expanding as when i am operational i can keep up with the movement of technology. Its just making the right decisions at the beginning is imperative to my success. Any thought would be welcome and thank you in advance for your time.

Per kW per month? Then tons of S3 could be the best but a lot of management. S5's are a great middle ground. If its per day, then nope. Typically we do per kWh math so maybe you can specify the rate.
2220  Economy / Exchanges / Re: Circle still offers instant purchase on: November 15, 2015, 04:22:43 AM
I'm not sure about Circle but I know that Coinbase offers the same thing which means you can buy Bitcoins Instantly using your Bank account and they will debit the money in two or three days , so that should be your best alternative in case you can't use Circle anymore .

Are you sure Coinbase gives you your coins instantly when you fund your account from the bank account and not a credit card? They are using ACH and I think that you have to wait for the money to appear in your coinbase account.

I might be wrong though!

The guy does say it'll take two to three days for the transaction to clear...

Are you certain? Sure ACH takes a while. But interact in Canada is instant. So while bank transfers are not instant, they are very quick. Takes 1 day for money to be deposited into my bank account too.
