Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 158. (Read 451277 times)

A PSU is not a mining cost as its not consumed during the process of mining and value stays largely the same.

My first prototype was running to bizarre issues and required a complete redesign. Novak and I spent some time going over a bit different (more flexible) concept, which I finally found to breadboard an initial prototype today and I'll keep working on it tomorrow. We're way behind on R&D for just about everything these days. If I can get the regulator working how I like, it'll actually be a first step in a couple other projects you'd probably be interested in.

Did you ever get further into your project to make a DC/DC supply for the S5? I haven't updated the firmware on mine since I got it to see if the issues with running at reduced volts was a firmware limit, but I'd be interested to know if anyone's actually gotten them down to 9V stable.

That is a potent statement there! SPT have insinuated (even overtly stated) their main customers are not home miners, thus it would make sense that they did not put orders in for current generation chips, simply because their large customers would not be interested in that soon to be superceded tech. Surely, that makes bitmain saints in the eyes of the home miner, price rise or not. Question is, why would you begrudge a saint a dollar?

More likely they didn't want to invest further in manufacturing current-gen technology whose bottom-end efficiency is pretty much on par with current or upcoming competition's stock efficiency, so they could put money into R&D for the next-gen stuff to actually compete directly with whoever Bitmain's worried about in another month or two.

Additionally, when factoring longevity into S5 calculations recall that BM1384 chips are rated to run around 0.25W/GH with sufficient undervolt/underclock. That takes the S5 from a 600W 1100GH machine to a 125W 500GH machine.

again i'm going to post this . . .

price of miner = usd 419 (as of 292 usd/btc @ BMT)
shipping = usd 50 (depending on location)
tax = usd 50 (depending on location)
psu = usd 50 (depending on user)
other additional costs such as upgraded/additional fans, lan cable, port switches, rental/hosting, racks/space, etc

so at bare minimum a s5 would cost usd 469 EXCLUDING tax & psu if applicable

@ current diff & price of btc @ usd 292.2/btc hashing @ advertised 1155ghs = 3.579/day * 12.8 days = usd 45.8 and so on with diff changes.
* btw, buyers WILL definitely mine @ a higher difficulty, note the shipping dates, soonest is a little over 2 weeks away & by the time it reaches buyer so lets say 3 weeks & i wont even bring up the june batch.

that is again EXCLUDING electricity costs & diff jump in the next 12.8 days or so.

if price & diff remains constant ( GL to that) it'll take at least 6 months to ROI ? in 6 months time i am very confident next gen miners will be available to the market & these overpriced s5's can be listed on the scrap metal list pretty soon.

if the buying stops the killing stops. i'd also advise miners to pull out from antpool to even out the overall network hashrate. needless to mention the p2pool that was not a real p2pool. less support = more pressure.

imo, BMT wants to clear it's stocks & taking an opportunity to make as much $ as possible within the shortest amount of time since SPT has stopped SP20 production & want to promote hashnest sales as much as possible or pressure buyers to buy the older stocks so that they can clear old stocks before next gen miners comes out ?

forget about what BMT is giving or doing anything for the community or making any profits or not, they (same goes to all manufacturer's, miners & traders) are all out to make $, $ talks & the BS can go walking !

just my very own opinion though. take it with a grain of salt or as an adivse. nothing against nobody. no one can stop buyers from buying or stopping BMT to raise their prices as every party has their own rights to do so but do it wisely.

Makes you wonder whether they were spooked by the same competitor that bitmain were worried about ... but were they, like bitmain, brave enough to place firm orders to have their chips fabricated?

Going by your anology, everyone in bitcoin mining is mad, as there is simply no better chance of ROI'ng at $320 (if you factor in the diff increase had bitmain's competitors taped out) than at $419, but I am happy to leave that in your mind. Simple fact is that you'd still face the same overheads at whichever price point you acquire the batch 5 or 6 S5.

PS. if the market is reasonably perfect and bitmain are right about their calculations to the effect of their competitor not taping out, then BTC should rise to ~$364 and above in the next few days ........ you can then get your S5 for BTC1.13

If spondoolies was ever going to do something now would be the time.

If paying by CC

Just the unit: US $445.03

my jan purchase

can be traced to this large holding account


https://blockchain.info/address/1KwA4fS4uVuCNjCtMivE7m5ATbv93UZg8V

and it looks like  191 purchased in the last 14 hours.

edit 220 purchased since  3//9/15  11:30 am UMC time    or when it opened.


so 220 x 1.2 th = 264th  also about   220 x 1.6 coins = 352 coins


an opinion this is slow sales.

Some days I feel like I'm the only one in the bitcoin economy not motivated by pure greed. It's too bad there aren't more people actually working to support and diversify the network and overall economy rather than focus on short-term profitability at the cost of basically everyone and everything else.

Are you mad? ROI and the current price of S5 have no business being in the same sentence unless it is to discourage people from buying.  At the current price of BTC, and assuming ZERO electricity costs and ZERO difficulty increase, it would STILL take 120 days to break even. Add any amount of electricity cost or diff increase, and it just ain't happening.  They aren't raising their price because people have a snowball's chance in hell of ROI'ing, they are doing it because they can, and have zero regard for their customers' respect.

It is for the same reason we mine ~ greed ~ plain and simple. What else would you expect from a company who is out to make a profit? Bitmain is the only game in town now so they will bend us over as much as they can.

SPT had exactly one product which wasn't specifically designed for a datacenter environment, and Bitmain price-hammered them so much they couldn't sell it except at a loss.

Additionally, anyone complaining that Bitmain price-hiked their machines by $100 in one day has good reason to do so because now they know full well that Bitmain has no qualms about letting people know they're being screwed. Sure the price of coin is swinging up on the news that their competition won't be delivering. That means the miner is expected to be more profitable for purchasers to mine on. But it also means that Bitmain themselves, fully capable of making positive margin at $320 per unit or they wouldn't be selling at all, are really in the mood to make another $100 profit per unit just because they can. Pretty dickish. Bitmain has good gear, sure, but that's crap and everyone knows it.

did anyone buy one today?

if so did you pay with btc?

if you give me the tx id in a pm.  I am willing to trace and figure sale for the day.

I have done it on this thread  just too lazy to read back 50 pages of posts.

I am going back to my purchase of one to se if I can pick up the trail.  I purchased 1 in jan

This so much.... SPT had amazing gear, and then suddenly poof! they went

Come off it! Honestly, as you say they can charge whatever they want, which initially was $320 and now it is $419. But that would not be the whole story. What would the majority of people mourning about the price now have said if the initial price was $411? I'd hazard a guess and say they'd still mourn, albeit a little bit less than now.

But you ignore the fact that the $320 price point was set with the assumption that a competitor was about to release a very efficient chip that would not just have redered the S5 massively in-efficient in comparison, but would have meant a spectaular rise in network difficulty making it reasonably harder / impossible for you to ROI on your investment in the S5 (so they set the price lower at $320). As it turns out (and we are to believe it from bitmain), that competition was blowing hot air and have not even been able to go to the foundry! That changes the dynamics in terms of network difficulty rise (also reflected in the filip in BTC value today) and means you can within reason ROI at the new price point according to their calculations.

I really want to err on the side of bitmain at this point as they have been on our side (home miners) and continue to be so. Look at SPT! They have abandoned the home miner ..... literally! Bitmain do not get the credit they deserve, though I have to put my hand up and say I too give them stick ...... not on this one though.

Especially after they found out a competitor will not tape out. So now they can charge whatever the fuck they want.

I get all this is business, I run a business of my own, but then to blatantly price gouge on insider knowledge and just laugh it all off.   " "

It is just a slap in the face. So, I guess SP-Tech will be getting my BTC when the new gear starts rolling out. Oh well. Business is business.

They can only "gouge you" if you let them. Stop complaining and vote with your wallet. If the market votes as you do, Bitmain will respond. If the market votes the other way, deal with it. 100 more messages complaining about S5 pricing is pointless.
