OR you could pick up 7-TH worth of S3's for half the price....

Wait a minute. Are you comparing a bundle that started hashing 3 months ago with something in stock? That can't be fair.

I understand you bringing up the worse case scenario.
But most are not in it...

Why it's a worst case scenario? I really think that most miners already own mining equipment and have a limited power circuit available. Optimizing it sound the best approach.

Makes sense to sell off what you have and buy the SP-30 or a few 10's..

Just too darn expensive to do that though.
Prices are too high.

[blaiser]

this SP30 is a joke !At this price it would be good if it's delivered right now,but when this sp30 comes out in SEPTEMBER it will be useless at this price !

Yea, I want to support Spondoolie and the community and keep myself in the game, but at that current price with a $300 shipping charge the most I could ever make would maybe be $2500-$3200. So, for something that cost me $5395 and only get the most $3200 out of it doesn't seem like a good investment. And I'm working with the current numbers, the September numbers would even be worse. I'm trying to keep myself in the game, and I'd really hate to buy a few Antminer S3's, but their so damn cheap it is hard to say no. I'd rather use a Spondoolie product for good support and a quality product but maybe this go around I'll just stick to buying bitcoin out right from now on and not have to worry about hardware. Apparently it seems everyone in the world is putting up their own data center these days. In my opinion, the main problem and concern we ALL should be worried about is power.

Opentoe, please do me the favor of replying to my question with your (approximate) percentage gains from your calculations. Just curious.

First batch was March+July then there was an April+July (I think both at 15K, at least April+July)
I am not sure if there were farmer choice left when the 10% discount started if so it was only for the latest unit of the batch.

July batch has been told to be a small batch probably around 50-100 and with the info provided by SP it will ship the last week of July.
August batch should come after that problably shipping by the 2nd week of August and due to the numbers I presume that it will be continously shipping until the last week of august depending on your position on the queue (april+august, may+august, farmer's choice, singles and group buy all mixed).

OR you could pick up 7-TH worth of S3's for half the price....

Or...

I'm ok with paying extra in order to avoid unnecessarily headaches. One box, 2 cables and I'm hashing in 2 minutes plus no reselling hassle. I would like to be busy planning the future, not dealing with present avoidable issues.

Plus the added power consumption. My house is filled with Jupiters and SP10s. I don't have any room available for another miner and it makes no sense to unplug some. So the only option is colocation. Good luck hosting 7TH/s worth of S3s in a datacenter

I asked my current co-location place about S3's and they said bring 'em on! As many as you want. All they need of course are power supplies sent to them and they'll hook them up on large bread racks they have there. And if I have a lot, they'll make a good deal.

You say your house is full of Jupiters and Sp10's, how the heck do you live? One SP10 is loud enough and you said your house is filled with miners? How do you watch TV? With headphones? What do you do in the summer about cooling everything?

Obviously I used an online calculator and it came to about %66. I used the Tradeblock site, which isn't set in stone with the output numbers, but I would definitely say they are a good approximate. Here is what I input for one SP30 starting in September.
https://tradeblock.com/mining/a/a45142e2e9
Maximum profit only indicates $3630, and yea, I was high with the difficulty increase cause I'd rather have worse case numbers to make a decision on. I think if I spend over $5k on a mining rig and then have to spend $300/month to co-locate I'd want a better reward than $3k-$4k. For 6TH/s in September I think $5395 is too much right now, that's all. I'm hoping all the numbers are correct. The reason I kept the diff at 20 is because at that time there will probably be a slew of KNC Neptunes online, thousands of Antminer S3's and, another one called Rockminer?, and then of course Spondoolie's. That's a huge dent onto the network, and if you adjust that difficulty setting on that page it does change your max profit considerably. The lowest change in 4 months has been %10.66.

I've never been a risky person, so I hesitate, and sometimes I lose out. The best thing I ever did was buy a KNC Saturn and then bought 4 upgrade modules. That little guy is still chugging along. I think if my house had more electrical resources and didn't have to worry about cooling I'd have mining rigs all over the place. It is addicting.

Yes there are some DCs that don't use regular racks shelves, but only a few. I still think that most of the pictures with S3s will be from regular homes not DCs.

You say your house is full of Jupiters and Sp10's, how the heck do you live? One SP10 is loud enough and you said your house is filled with miners? How do you watch TV? With headphones? What do you do in the summer about cooling everything?

I got 1 free empty house.

So you started with 20% increase, but we have:

Code:

Estimated Next Difficulty: 	17,609,327,556 (+4.70%)

Let me cite from our favorite AM (main?) shareholder

Yes but with the difficulty derivative I find it extremely difficult to predict the next difficulty a week away. Even predicting the next difficulty ~3 days away is not easy.

Because some people find it doable.

...with more or less results I might add.

These numbers are very different from the bitcoinwisdom calculator.

With $.15, 6TH, $5000, 2500w, , $615 BTC, start on 9/1/2014

20% increase:
bitcoinwisdom shows a negative return of ~ 5 BTC at the end of 2014 when operating a SP30 become cash flow negative.

15% increase:
bitcoinwisdom shows a negative return of ~ 3 BTC at 2/19/2015 when operating a SP30 become cash flow negative.

10% increase:
bitcoinwisdom shows a postive return of ~ 2 BTC at 6/24/2015 when operating a SP30 become cash flow negative.


So how do the tradeblock and bitcoinwisdom calculators differ  ?

[Collider]

I would recommend this calculator:

http://btcinvest.net/de/bitcoin-mining-profit-calculator.php


It lets you set an increase per jump aswell as an amount by which this increase decreases. (Aswell as time to deployment etc.)

[tzortz]

Hadn't seen that calculator.

Thanks.

[Collider]

Hadn't seen that calculator.

Thanks.

Happy to help.

As the bitcoin difficulty is ultimately limited, I suppose this one is the most accurate calculator if you get the difficulty decrease roughly right.

[frisco]

So how do the tradeblock and bitcoinwisdom calculators differ  ?

Tradeblock as most calculators uses a diff increase per month, instead bitcoinwisdom uses a more realistic simulation where you can set the diff increase per diff jump and even adjust time between jumps. For example this month we had a 25% jump and probably will have a 5% diff jump, that means a 31.25% monthly diff jump.
Obviously is a lot more precise to calculate both jumps that only one even if the monthly jump is the same a 31% jump at the start of the month is a lot worse than a 25% + 5% jumps that is worse than a 5% + 25% jumps.

So to get more realistic estimation use bitcoinwisdom or any calculator that calculates every single step instead of monthly jumps.

As a side note I really don't see the point to estimate a diff jump decrease over time as time has proven many times it will not stabilize unless Mining chip designers stop making new ones with improved efficiency.

Over time the magnitude of the difficulty adjustment may go up, but the percentage will go down.  Obviously there will be spikes here or there, but as the network grows, maintaining these large increases starts to push the logistical and physical boundaries of new hardware deployment.  This isn't even taking into account the profitability.

whatever you linked to on traderblock assumes 20% increase in a MONTH, not a cycle.
20% is definitely on a lower side, but possible in 6mo
I would use 30%/mo. In this case-about breakeven in april 15.
here is is:
https://tradeblock.com/mining/a/5d5e92893d
bottom line: profit is possible ONLY if difficulty stagnates to below 30%/mo AND bitcoin increases in price.

It seems that BitFury started massive deployment of their LightFury script ASIC: https://bitcoinwisdom.com/litecoin/difficulty
They completed deployment of their 10MW DC in Georgia in 4 weeks, and they probably allocated some percentage of it for deployment of their script ASIC.

Nasty surprise to KNC and Titan buyers. It will get much worse.

[Collider]

Well, bitfury is king and anyone who underestimates him is always in for a bad surprise

I would like to get your professional opinion on this:

Bitfurys 55nm Asic uses "experimental low voltage transistors" and is apparently hand-routed.

Would their performance not benefit from die shrinks?

Isn't Litefury just some small 55nm SHA miner developed by a 3rd party using old Bitfury chips?

We've seen all the three 55nm ASICs dies. All are custom made. Impressive work.
More impressive since Valery Nebesny is self taught with software background and without any formal ASIC design background.

Doing custom to 40 and below is much harder. In PickAxe and other ASICs we're doing, we're taking the 80 - 20 approach, customizing the cells that give the most benefit.
Still using automatic tools for the routing.

Edit: BitFury is using UMC for their 55nm ASICs. UMC is limited in advance processes compare to TSMC

LightFury, not LiteFury. 55nm fully custom scrypt ASIC, developed by BitFury CTO.

[Collider]

How does 55nm chip cost compare to 28nm?

My understanding was that wafer cost would be cheaper, but you obviously have to use more area per GH. (Is it therefore around the same price per GH?)

Wouldn´t packaging costs be higher when you have more chips to package (or is this a very small difference)?

PCB design would probably be easier as you could go with very small heatsinks etc.


At the end of the day, Bitfury is probably already very limited by the 55nm process, as he probably has most of the optimisation done by now (in his 2nd ASIC generation).
On the other hand Bitfury has secured a $20m funding round, and some of that will most likely be used for NRE of his next generation chips.
