I think Bitmain has demonstrated a keen sense of the Bictoin mining market, and will price an S2 upgrade accordingly. I mean by that it will NOT be cheap, nor represent any kind of huge leap for cheap. After all, once all the engineering and stuff is done, the easiest thing to do is adjust the price. I expect it will appear pretty pricey, and IF (and only IF), they need to respond to a competitive problem, they'll drop the price. Why else would they do anything different?

I don't own an S2, and am just looking at their pricing over the last 12 months.

You probably want to take this to the "Marketplace" sub-forum. Particularly, since GPU's have very little value for actual BTC mining these days. Alt-coins maybe, but not BTC.

I agree with Xian01. While I don't completely grok some of the more esoteric electronics, I get enough to follow along. Thanks for the very open discussion of what you are doing.

Start with www.westhash.com, and scroll down about a page. You'll then see a table for Sellers and Buyers, listed by algorithm. I expect Nicehash is similar. I use Westhash since I am in Minnesota, USA.

No way to know, since it's a hosting facility, and not a private mine. Also based on the comments from the last few days, it may be at closer to 0Ph for now. Nice pictures, not sure about the actual result.

You also need to consider your competitors in terms of what they effectively paying for 1.1 TH of hashpower. Using Westhash, they are paying better than $3 for an S5 equivalent miner pointed at them. That's with a $225 BTC price, and their current rates. This all changes by the hour, but offer $2.50/day just doesn't make sense to most miners. This is what you might pay a friend to pay of hist costs, but not a stranger to mine on your behalf.

I am curious about something regarding when I "rent" my SP20 to Westhash. Over the last 24 hous, the "advertised" rate on the Westhash website has been well over .0127 based on my sampling of it. Assuming that we have two identical 1TH miners, but they use different p= values (say .0110 and .0120), would we expect a different payout for the two miners? I am trying to understand if I need to "demand" a higher rate, still below the advertised rate, in order to maximize my return.  I can see many different implementations, and how they might work.

Insight and experience comments would be greatly appreciated.

Looks like the board design and PSU guys did all the work, and ASIC guys sat this one out. Interesting set of choices. They must have ordered a bunch of BM1382 parts. The yields on those must be pretty good.

Did I miss the price in this announcement, or is that only available on the ordering page?

If you are using Westhash for this, you might well be renting my SP20 along with others to get your 7.5TH. Maybe we both win.....

Well, it appears that at least Westhash has gone back to being "in balance" where the cost to rent is higher than the price to sell hash to Westhash. If I am reading things correctly, I am getting up to .0235 for the hash I am renting to them. This is roughly double what I think I would expect to earn at almost any other BTC pool. None of this makes sense, and it obviously can't last, but it is VERY interesting.

I don't really know how you find out the wiring/breaker information without asking. Six outlets could easily be just one 15 Amp breaker. It might be two. It's almost certainly NOT 6, nor even 4. Besides electrical capacity, you might find that it's impractical temperature wise to have a 1000 watt heater in your office. While it may not seem obvious, a 1000 watt miner is virtually identical to a 1000 watt little heater in your office. Watts are watts, regardless if Bitcoin is produced as a byproduct.

I am curious about reference to "last gen" as including the S5. So if "last gen" is the S5, what is "current gen" hardware? I am not trying to pick a fight, just trying to understand.

I consider the S5, and SP20, and Aavalon 4.1 to be "current gen". I would put the S3 in the "last gen" category. That's just me though.

Thanks again for the prize you supply, suchmoon.

You might want to take your cues from the other tenants. What do they do? What kind of equipment might they have in their space? What kind of power draw might they have? Once downside to mining in this kind of environment is that it's usually 24x7. Most small business offices would be more like five 10-hour days, maybe a bit more. Almost none would be a round-the-clock 7-day per week operation.

Besides what you can actually safely pull from the wall outlets, you will find that there is actually some kind of "cap" on the electricity usage. It won't be stated directly, but if/when your electricity usage turns into 10x what the other tenants use, your landlord will find the clause in your lease and point it out. Stratobitz found this out when the property changed hands and the new owner did a "walk through". He is now selling all his S5's and S3's. One or two miners might be passed off as "office equipment". A dozen won't, regardless of power usage.

Phillip,

it's seems like you feel duty bound to always take the -1.11% change guess, based on some previous exchange with another member. I would be happy to have that assigned to me, so you are free to choose what you might actually want. Feel free to do that if you want, and I won't complain or request a change later.

Thanks for organizing these, and also suchmoon for his generous .1BTC payout.

It all just comes down to watts. If their power usage is the same, then their heat production is the same. Liquid cooling or air, it all just ends up as warmer air (after having passed through the radiator on the C1).

While everybody talks about cheap electricity, there is another component required for mining: reliable Internet access.

Without good, not necessarily fast, Internet access even "free" electricity is of little use.

I think one thing that's going to have to change is the vaunted anonymity associated with a Bitcoin wallet address. As it stands today, it's like having a massive number of Post Office boxes, with no names attached. The only information associated with a transaction is the source and destination wallet address. It would be like me putting a $50 bill into an envelope, with only my PO Box as the return address, and sending it to another PO Box. It's got all the benefit of cash in that regard. That's exactly why hardly anybody uses cash except for things they walk away with in person. And they want a receipt to deonstrate they paid, in case they want to return it. I am not aware of any significant side transactions that happen with cash, it's all something else, usually with lots of identity info attached.

While there is huge amounts of work to prevent "counterfeiting", and overspending, there's still a lot of trust required to do anything with Bitcoin. Just look at the use of Escrow, and "trust ratings".

The latest bicoinwisdom projection puts the new difficulty at about 47.6 Billion. Looking back through the list of prior adjustments, that's like a "reset" back to March 8th if it holds true.

Just an interesting viewpoint, for a Friday afternoon here in MN. 

Might want to update your signature for asicpuppy.net. It still mentions R-box.
