Bitmain will be releasing S15 and T15 on 8/11/2018

[philipma1957]

just buy BTC for same money... as next november u wont have same btc by mining. And if you like u can buy one S15 for 400usd that time and continue mining
i dont know,mabye i sounds sceptical, but there are better miners than S15 and i see better option to buy btc directly when the price is relative low and save your nerve, noise,etc.. however 5cents sounds good.
for last 6 months diff went up from 4T to 7T+its almost double = your profit half. and then in 12months it will be even less. so if u see today that u will mine with S15 in year 0.36 then u are mistaken. if u will mine 0.2 that wil be success. now u can buy for 2 000usd around 0.3BTC lets say.

my point is it is overpriced, it should got for 800-1000 max with psu.

the diff has not risen much  since august 24th.

At this point, its better to do absolutely nothing and maintain the farm as it were. Bitmain will definitely lower the price anyways because from what I've heard, the preorders were subpar at best. Either that or Btc price goes up alot......in which case it makes more sense still to do nothing and hold your Bitcoin.........

[QuintLeo]

Exactly right, these S15's are overpriced by almost 40%...

Much higher efficiency, which has always been a good justification for a new miner model costing more per hash.
S15 will be profitable for years, the S9 will probably be a money loser at 3 cent electric by this time next year.

For years?   bzzzzzzt

[minefarmbuy]

We'll there're more for sale should anyone want one.

I also feel before these even ship out, either price of bitcoin will go down or difficulty will jump up a considerable amount.  They will also have "batch 2" orders in a week or two at a much lower price to compete but with another 1-2 month shipping delay.
They did this with the S5, S7 and S9.  S4 there wasn't much competition and it was a true shortage of miners versus demand at that time so at times prices would go up and stay up.
Back when it was an actual good deal, they sold out and stayed sold out until the next batch.  I haven't seen the S15 or T15 sold out for several days now.

Edit: well, there is the bitcoin price fall.

[Steamtyme]

Hard to say what's going on with them ATM, I'm pretty sure they sold out the first day launch. Whether they call that batch1 or label things in that manner anymore.

Can't be hurting as I still see the 2 unit max per order through the site.

Well were already seeing a large price decrease whether that holds as the new normal or not is yet to be seen.

There is no new "more efficient" node anticipated to BUILD miners on for years.
Is that hard for you to understand?

In fact, there is some question how much longer semiconductor node CAN continue to progress - GMO's over-optimistic projections to the contrary.
Intel and IBM in particular have both stated that "pure silicon" has reached the end of the road - IBM's current "next gen" process design work uses a MIXED silicon/germanium die while Intel has been quite mum on their plans for anything past their current 10nm node.

The old "new miner model every 6 months" routine died when ASIC mining hardware caught up with semiconductor state-of-the-art at the 14nm node (S9 and such), and CAN'T ever return.


Just noticed something I find a bit iffy about the S15/T15.

"exposed die" design on the chips.

Does anyone remember the massive FAIL issues associated with that concept on the Athlon Thunderbird/Palomino and same timeframe Pentium 3 generation CPUs that ALSO used an exposed die?

Probably less of an issue with the "glue-on" heatsinks Bitmain uses, but still a bit iffy - and definitely NOT THE NORM that Bitmain claims in that part of their "overview."

Thank you for your apology.

Thank you for your apology.

What apology?
I was explaining why your comment was not only wrong but rude.

[minefarmbuy]

Soo much drama in the LBC.

Your plan is nice on paper, mine long time, but unfortunately right now if we assume a flat price and over 7 cents per kwh you're not going to ROI before the halving  

Of course, prices might go up but at that point just buy directly BTC.

The s15 might be efficient but it has a price tag that is dragging it down and this is not a normal industry, I doubt there is something out there where you have to plan a halving in global markets every 4 years.

With an s9 you're going to ROI faster and start making a profit faster, the s15 is indeed for the long run but it might take way too much time to make some bucks on it.

Slash the price at least 25% and yeah, it looks attractive but at its current price...nope. Just no!

[sidehack]

Don't forget how much money you'll have to put into maintenance and repairs to keep it running at spec for that whole time. Bitmain gear isn't built to last for two years.

No, you're wrong!  WRONG WRONG WRONG!    lol

S15 is way overpriced...in total agreement with what you're cookin'

This. As someone who has been running Bitmain gear from the beginning I can say for certain that their gear fails over time. I've had hashboards, control units, fans, etc all go bad in no time.

I think a lot of people like to forget and overlook how much maintenance and failures add to the cost of a miner. Add to that the inevitable downtime when things go wrong and you end up pushing the ROI out much, much further than what is perfect on paper. We used to have more room in the margins for these added costs. Not so much now. At least when it comes to mining BTC. Its slowly becoming a fools game that only benefits the ASIC makers.

[QuintLeo]

They tend, from what I've seen and many other reports, to have a lot more issues with "infant mortality" than death over time - like most electronic gear, especially when it's pushing a heavy load.

From what I hear they had issues with the chips and wafers so this is good advice unless you enjoy looking at a machine while parts are away for repair or replace.

[betajuice]

Is there a way to order a larger amount of the S15's ? From Bitmain's site, they are limiting 2 per order. Are there third party suppliers that will sell them in bulk?

Contact our site, we should be able to get a quote.

I might budget to include units for possible repair. Maybe order an extra or two to swap pending your farm.

So we're down from 1475$ to 1204$ for the January batch...and lost one TH   on the way also but same power 1596W and same 57J/TH.
Still over a year to ROI at 4c/kwh.
