Sorry to throw the subject back a bit...

But are we really saying that even if you have free electricity, a S7 with an Bitmain PSU wont ROI for 5-6 months???!?!?!

or is my maths totally off?

At this moment income from each of my s7b8 's at work (free electric) is paying just over $8/day so not counting what the Halving will do If I buy a batch 10 today it should ROI in just over 100 days. Yes I know dif rise etc will change that.

That said, for my investment in upgrading s2/3/4/5's to s7's I do not look at per-machine ROI I only look at power consumption/THs and my available BTC to spend at that time.

When I started after about maybe 7-8 months the Ant Pharm was already paid for and from then on was dedicated to paying for upgrading and increasing hashrate. Since then the total miner farm income at any point has covered it all plus paying for quite a few nice toys from what was TigerDirect.

Since current pharm income is now banging around 0.3BTC/day that means I could get another s7 every couple weeks until I run out of available power (close to it already) if I don't mind not increasing the btc 'surplus in my wallet  Not gonna happen soon as have to replenish after buying my last 3 s7's a few weeks ago

Though do gotta say at current price for the batch-10.... maybe just one more? <said the junkie>

so even with the HST code on my fedex shipment under my street address, and EIN/Tax ID and under shipment notes for Batch 8 and 9 I just received a bill in the mail from fedex for 35 bucks for the customs fees.

so I think the HST trick is either hit or miss, or completely useless

$35 "fee" as it was described to me was just the cost for them to inspect the package/confirm contents if they choose to do so, regardless of the code.  I've used DHL, Fedex, and UPS for Bitmain and the best way to slide under the radar is to simply order 1 miner at a time so the value "looks" as low as possible on the shipment.  However with that said  I had video cards shipped from Canada to US which is definitely a "free" item and was also charged in the past.

And thankfully in the US at least is less than the VAT tacked on that most folks across the pond have to deal with.

[nhando]

Yeah, FEDEX told me there was no Custom tax for my orders, but I just got a bill for $35 today for my small order even though I have the HST code listed.  Not looking forward to seeing any bills for the larger order!

Are you running 70TH in your own mining area or is it being hosted?   And I would agree it's a slow ride anymore.  I remember when it was a quick 3 month ROI.  But no longer is quick and ROI mentioned together.

Patience and being able to hold long term I think are two important things.  I like to pay off electricity out of it and hold the rest.   Will see long term how I end up on my investments.

50TH of that is at work where I have 20kw of free electricity the rest is at home where the bill is $0.15/kwhr 

That is awesome on the 50th part if you managed to get that for free.   What type of work do you do if you don't mind me asking?  That is a lot of free power.

Sounds like a great setup though.

I'm co-founder of and Sr. Engineer at http://www.synchronlaser.com/ so in a way the free electric is part of my comps 14kw of that is concentrated in one area that can tolerate the noise and heat of what is now mostly s7's, the rest is mostly nice quiet s3's in various offices for supplemental heating aka space-heaters along with my 1.2THs (re-branded Dragon) rig I eventually got from AMT. Yes, it is still running perfect 24x7x365 since Aug 28, 2014.

Yea A1 really were good miners those dragons were good miners.  Some companies shipped with cheap PSU's was only issue I ever had, but solid miners.

Now I'm not only jealous of your free electricity, but of your lasers.   That is some very cool gear you have there.

thx. We (well, I) am in the process of commissioning a new toy that arrived a week ago http://www.trumpf-laser.com/en/products/solid-state-lasers/short-and-ultra-short-pulsed-lasers/trumicro-series-5000-femto-edition.html to apply my majik touch/insights to with the goal of pushing our systems processing capabilities further.

That sucka costs over $450k and Trumpf has lent it to us for free for at least 6mo to play around with. For our end, so far ~ $120k into a new testbed workstation to use the laser with. Of course their goal is for us to find/improves uses for it so they can sell more. Since each of our systems usually has 4 heads meaning 4 lasers... You get the idea. Knowing of our work with fiber lasers from their subsidiary that supplies them to us it should be a safe bet for them to make. They know our primary customer in Taiwan has very very deep pockets and when we say we can provide systems for them to produce component packing densities no one else can economically reach those pockets open very wide. Only catch is for us to first prove it to them.

 The rest of our lil part of the industry supplying laser micro-machining systems are still a few years behind figuring out how we do what we do so blisteringly fast but nonetheless are catching up so time to leapfrog them once again with beyond bleeding-edge mfg tech

Way OT here... Gotta watch out for the Powers that be....
Unless perhaps Bitmain would like some help in making their miners smaller that is. If so give us whistle

3D printed Exhaust fan grillz and exhaust Duct connectors.  Pretty pimp and works awesome, fixed my screeching noise issue.

[mavericklm]

Very nice!!!!!!
Are those for 12 or 14cm?

[nhando]

It's 12CM as it's designed to fit the S7 120MM fan or any other Miners that uses the same size fan (ie S3, S5, Avalon 6, etc).   Works very well.  Here's a picture of it on my unit.  Noticed I used double tape temporarily until my longer screw arrives.

[Poloniex Matthew]

Very good news, numbers are pretty good as well.

Antminers will take-over mining business it seems

That certainly does seem to be the case. Nobody else bothers to release new hardware besides Bitmain and Avalon.

Love the Avalon, really hope they can stay competitive with pricing.  Seems like all resellers are still selling them at ridiculously dated prices of $1300-1400.  Only our forum members like Philip / Kilo17 are doing members a favor in helping us get lower prices.  Even then, the batch 10 S7 at $780 is the final nail in the coffin for Avalon, unless they can come out with a more efficient / powerful box or drop price to the 600-700 to stay competitive.

yeah we got out about 35 units at 1100   but the s-7 at 925 or so is tough.

I no longer will buy from bitmaintech since they never gave me anything for my low hash s-7 from batch 1. 

 I sold the unit with a 150 usd discount because ti won't hash above 4500.  They gave under hashers about 67 or 70 usd for the batch 1.  I made 7 more purchases asking for a coupon to make up for the low hasher they never answered me or gave me anything.

So on Jan 31 they shoot me 9 coupons for .05   Which is okay but never addressed my underhashing gear.

While they used to be good to me a year or so ago..


 Right now they just ignore me .

I am in a funny spot as I won't buy from bitmaintech anymore and the Avalon6's are a bit too high in price.

Even if I got a really solid coupon from bitmaintech they no longer deserve my respect.  Sad but true.

Oh well.

If Avalon dropped the price to 600-700 I would buy some. But honestly the S7 is dirt cheap now. I'm done with Bitmain though after my Batch 9 failure rate and their "vacations". Had to buy 2 more to fulfill some orders, but I have none left now and won't be getting more. Honestly I'm feeling what philip is, don't really know what my next step is for miners.

[adaseb]

Yeah I really wish the Avalon was priced more like the S7, would buy one also, even at the slower speed and worse efficiency.

[jstefanop]

Are people still buying these?? In 2-3 more 20% diff jumps these will be nearly break even for $.1+/kwh areas of the world. Forget it when the bit fury stuff comes online...

I have purchased more then 30k from s-7.

They have lost interest in me so I can't chase them anymore.

Anyone want 9 .05 btc coupons ?

Bitmain probably is too busy counting all their money then worry about our concerns.

Difficulty is going crazy I wonder if they are full focus on making gear to have racks full during Chinese holiday's.   Also someday they will need a new chip.... I wonder where their dev is at.  They could have one ready to go or still need dev, no one knows.

All I know for sure is price of is going down a good amount with batch 10.  And I wonder with difficulty change what next one will be.  We live in interesting times.
