Topic: LKETC 5T 1000W is it real? (Read 4557 times)

Sfards has barely shipped anything. Not really worth being responded to, especially if the ONE report I've seen about "in the wild" ones is a good representation of the (UN)reliability level of the SF100.


 I'd already decided I wanted to see (1) a major price DROP, AND (2) quite a few reports on the SF100 before I was willing to risk anything on their design - Gridseed's JUNK board-level design work on both the orbs AND the blades was not what I'm interested in putting up with on a miner ever again.

My interpretation of the above is that August 20th is the date for more details. That doesn't imply to me that they will actually ship in August. I expect we'll get specifications, and possibly pricing and more dates on August 20th.

I kinda get this feeling the various big ASIC vendors are waiting for the others to actually ship something, and then they'll respond. It would appear that SFARDS didn't trigger them, though maybe the S5+ is the response to SFARDS.

Ouch longer then most of us were wanting to wait.  But if anyone has inside info it would be him.   He sold a ton of their other gear.

Guess we will see but I really hope we are not waiting 4 months.

pcfli, buyer/hoster of a lot of LKetc stuff says that it's eta is December

Where does the August 20th date come from?

 (edit) never mind, saw a reference to "more announcement" in a different thread.

It will (should) be real! Let's just wait for August, 20th. 

Their competition "right now" would be the Bitmain S5+ unit - 7.7TH at $2750 + shipping right now, though it eats 3400 watts - or the S5 (5xS5 right now would be $1760 + shipping with the recent price drop)

Their REAL competition will probably be the S7 when it finally starts selling, though it's hard to tell since Bitmain has not announced specs yet for the S7 much less pricing.

 70% of the hash for a third of the power cost puts it in the same ballpark of "worth" vs. the S5+ IMO with a small advantage to the Lktec due to the efficiency, but I personally think the S5+ is noticeably too high (it should be closer to $2200 plus shipping to have decent chance at ROI, and IMO the S5 should be back down to about $320 for a decent chance to ROI).

 Also, based on a LOT of reports I've seen, Lktec would be better off NOT including door-stops-to-be, errr power supplies. Just leave space in the units for a good quality ATX power supply bought locally would be better.

I doubt that they will set a very high price. When the Dragons came out, they had a pretty good pricing. I ordered several miners with them directly, and the operation went smooth every single time. Only grain of salt: All the PSUs died very quickly, so if they haven't found a new supplier, I'd recommend to order high quality PSUs in advance...

1% difficulty increase is a non-starter. Even with the very low diff increases since around turn of the year the AVERAGE has been close to 1.6% so far this year, and the last month that's been ramping up and seems like to STAY ramped up some for a while due to deployment of "next gen miners". I've been using 2% for my recent estimates on ROI and even THAT might be a bit on the low side for the rest of this year.

 This miner might sell for $3000 as specified (Lketc does have a decent track record on that) if it's available in the next month or two, but IMO it would be better priced for a reasonable chance at ROI at $2499 WITH SHIPPING if available by the end of August, then drop that at least 5% per month after that.

 The .2GH/W figure seems a bit iffy though, given Innosilicon is only CLAIMING a 60% lower power draw over the A1 in their post. VERY nice if it actually happens and seems to be possible though given the process (half the process size as a general rule should yield ballpark 4x lower power draw at the same clock, though somewhat less in recent years as semiconductor process technology has entered the realm of quantum effects being significant).

 Lketc has been around long enough and has delivered enough on it's claims that I'm willing to say this is probably a "waiting on chips to hit production" preannouncement and NOT a scam. I'm mostly just waiting to see (1) what the price ends up being to the end user, (2) what the specs and price on the S7 ends up being, and (3) when this stuff finally hits end-user sales.



 I would anticipate a few years for the current "in the works" tech to try to ROI, as BitCoin ASIC in this generation catches up with the "leading edge" of semiconductor tech in general, and given that the pace of semiconductor tech generations is slowing down noticeably due to increasing quantum-level issues. We're still a few generations away from "one electron = flip the gate" but that light IS visible at the end of the silicon tunnel.....

Nancy has been unresponsive to emails for days now.

First 1T dragons were in this area (think first batch might have been a tad higher).   It's really hard to say what price will be.   LKETC got good at selling even at lower price as product went down to less then 1/3 of original price and down even more.

A lot will depend on competition.  Who has next get chips and what the are doing.  We need multiple next gen fighting for business for best customer prices.

let's wait and if the price tag shows a 3k.. then they will take my money!

yeps. takes a VERY long time to ROI even with free electricity, 0 pool fees & assuming 0 maint costs such as internet, rent & others such as setup fees.

rough math says 169 days without hiccup with btc price of USD 275 a piece diff at 1% increment. that is miner priced at USD 2000, 0 s&h, 0 tax & miner plugged in right now.

those are good numbers.  the key is  it runs way better then power costs.


mining to roi in house for guys like me at 18 cents and 10 cents no longer happens.

I buy gear that allows 6 to 9 months of profit then sell to a guy with cheap power.  I can not roi any other way.

my pool fees are under 2% and no variance.

if what i punched in is correct ?

pool fee 3% includes exchange fees (just an assumption & a quickie)

don't look good at all sadly my friend.

All good points so let me change it just a tad.

People would be willing to pay 3k today if it shipped asap arriving in home in under 1 week.
I know I would buy it for 3k today and more then likely profit with it.


Now my post to the thread is still speculative since  I am not getting an offer to buy it today and have it shipped to NJ, USA arriving on the 29th or 30th of July. I am willing to take a price risk on BTC staying above 250 short term with an increase down the road.

As for luck this would mine at f2pool no luck involved.

Shipping is around 200  so 3200 giving me as you say 4700-4800 at 1000 watts the math works and for the next 75 days my power is 18 cents it then drops to 10 cents for  OCT 1.

I can mine this unit until May of 2016 before I need to worry about June 1 summer rates in the year 2016.

i doubt so. theory & practical is VERY different. it greatly depends on the btc pricing at that particular moment.

don't forget to add shipping & taxes before the miner even arrives in let's say a week so ROI is another week away.

mind to share some #'s on how long does it take to ROI say btc price at USD 275 assuming it is constant till ROI comes knocking on the door.

miner cost @ USD 3000

shipping cost @ USD 200

tax @ USD 100

so it's USD 3300 to start with 4.725 ths assuming -5% performance due to various conditions.

also which pool one is going to point it to ? again depends on luck. again assuming it is pointed to antpool on PPS & get paid 97.5% after fees.

exchange fees to sell the btc mined @ -0.25% that excludes currency conversion but let's just use USD.

so to sum up in REAL world expect:

-miner to perform 5% lower
-pool luck (ain't gonna be jolly happy always) fees too (if there is any)
-exchange rate at that present time + exchange rate fees + withdrawal fees or + currency conversion fees say 0.25%
-diff changes

total before anything starts it would be USD 3300 for the miner to arrive within a week & abt -6% less from the points above. i'd do assume it does takes a while to ROI.

the s-5  at freq 375 does 1250    so 4 = 5th   but the power is 2600 watts

if this is 5th at 1000 watts  they can get 3k.  

here is the reason it put 12 cent to 20 cent people back in the game.  at 18 cents under current conditions .  this earns more then 260 a month after power.

So a guy like me with 18 cents in the summer and 10 cents in the winter gets back in the game.

4 s-5's cost me say 1800  for the same 5th but at my 18 cents right now I make only 40 a month under current conditions.


I have no margin of diff or price with the s-5. so it is effectively worthless gear if I mine it in my house at 18 cents.  each one make me 10 bucks a month.

SO I would love to get one of these today for 3k.  But Nancy of BW.com is not sending me any pm's here to review and or buy one.  So once again oh well.


My point is these will sell at 3k.

let's see it out there asap!
