Thanks for your info but about 7 nm nodes TSMC according to their website NOT ACCORDING TO ME has divided the 7nm segment into 2 divisions and on their website it specifically says one for mobile phones and the other for high computing power chips before that they have not divided this into 2 segments, may be these high computing power chips are for some other use also rather than only ASIC MINERS

If I were you I would buy antminer l3+ and have already bought 10 machines due to arrive this week bcz I am HODLER of coins and will keep them 50% in BTC and 20% ETH 20% in LTC and 10% in other promising coins like digibyte game and  siacoin

I would like to arrange Meet up in Karachi Pakistan for bitcoin miners and traders those interested please PM me or write here

There are Natural gas generators which starts from 6 kw to 200 kw but are very expensive and you can't run them for 24 hours so you have to buy at least 3 generators to run 8 hours each.
First you must check the quality of your gas and assuming that a company was extracting gas from ground the fittings will be there so you can rent a gas generator and try to run on that gas if it works fine than go for a big generator. For 20 antminer 27 kw you will probably need generator of around 35 kw.
With free gas your per unit cost of electricity for maintenance and depreciation will be around 0.04 US$  so it's highly profitable but you have to be very cautious about the maintenance of generators you just can't leave them like antminer

Thanks for the update about TSMC it was really informative

Hash2 coins pool is good choice if you want other coins rather than Ltc and if you want your coins changed to one coin like BTC LTC ETH you could use prohasing pool they mine the most profitable coin and give you reward in the coin of your choice with I think 6 to 7 choices

Thanks for your reply I didn't said that bitmain is a bigger customer than APPLE AMD or NVIDIA of TSMC and for your information AMD fabricates it's chips from global foundry and not from TSMC Taiwan.
TSMC is running at 65 % capacity and they are taking mining segment seriously and for your information according to TSMC website they have stratified their chip fabrication into 2 divisions one is for mobile phones and the other for high computing power chips.

I think you know nothing about Bitmain mining machines and you are such a novice to mining machine segment and was not accepting this type of statement from a legendary member that bitmain only manufactures a couple of thousand miners each batch WHAT A JOKE
Bitmain has currently 3 active models S9,L3+ and D3  and if you look at bitmain Chinese website and have a common sense to use a Google translator you will know that in each batch their are around 5000 miners and with 3 to 4 batch released every month for each batch it makes around 45000 miners only for Chinese market and the same quantity  for international market it make around 80k to 90k miners and if you multiply it by 189 and 288 chips for some models you will get a hell lot a figure not as big as APPLE but a substantial number.

Bitmain purchases chips from TSMC foundry Taiwan and by the number of miner batch release dates now bitmain have become one of the major client of TSMC and they to  are taking mining segment very seriously
If you look at TSMC website for the 7 nm nodes segment they have divided that into 2 stratums one for mobile chips and the other for high computing power chips so they are taking mining segment seriously.
Now for the speed for the new model of S9++ or S11 (whatever they name it) we have to calculate the computing power for chips of newer nodes according to TSMC website they have started the tape out of nm 7 nodes in April and by the end of this year they will supply these 7 nm FinFET nodes to more than 10 customers and surely Bitmain is one of them.
Now come to speed of that 7nm miner we know that S9 speed is 14 ths with power consumption of 1372 watts
By looking at the 10 nm nodes efficiency according to TSMC website they are 15 % faster and consumes 35% less power so for a 1300 watt miner the speed would be 14×1.15×1.35 =21.73 Terahash for around 1372 watt miner

And if bitmain decides to skip 10 nm nodes and go straight for 7 nm nodes which I personally think they are planning and to raise funds for that bitmain is also issuing an IPO of 200 million $ in USA the speed of that ultra fast miner would be again according to TSMC website the 7nm nodes are 20% faster than 10 nm nodes and consumes 40% less power so the speed of that miner will be 21.73× 1.2 ×1.4 =36.50 Terahash and that to hypothetically

So 75 Terahash with 1200 watt is not possible

Typically chip fabrication cost is the major part of the miner cost and it's cost is fairly standard in the industry for a specific process and as bitmain uses TSMC foundry chips from Taiwan their average cost per wafer is $ 7500 to $ 8000. From the information we get about L3+ specifications we can assume that around 24 to 28 miners can be build from 1 wafer so typically the miner chips cost around 270 $ to 300$. The cortex A8 microprocessor, heat sinks,controller,pcb, fans and casing price is fairly standard if you buy it in bulk it will cost around 150 to 200 $ and according to the batch release date analysis of bitmain it look like they manufacture around 60,000  miners of all types per month so it is assumed that around $ 100 per miner will be their production/Labour cost so if we add all that the total cost is around $600.
The major cost of any miner launch is the development cost of the wafer that is chip designing, tape out, testing etc which is near 10 MILLION US$ but assuming how many miners bitmain have sold it has been recovered in the initial batches. Now according to TSMC foundry website they have now dedicated segment for the development of chips specifically for high computing power.
So in my opinion bw can sell LW21 around $1500 in fact bitmain sold their L3+ for $1291 in June

Can bitconnect coin be added to your pool please reply it is a scrypt coin

Can we mine bitconnect coin with L3+if yes than how

Hi can your pool add bitconnect coin

In my opinion bitmain cant have unlimited datacenter space and electricity they must have a saturation point to run their miners for their own use so they have to decide which miners to run and currently D3 is most profitable miner to run so they are clearing spaces of L3+ for D3 to run by themselves so i think that's why they are shipping L3+ ahead of time to clear their data centres and that could be a win win situation for both the miners and bitmain WAITING ANXIOUSLY FOR MY 10 L3+ MINERS due to ship on August 28 may be i will get them earlier.

Hi

I am in for 10 pieces price should be 1500 USD delivery with in a week because these machines will earn around 400 usd in remaining days of August and 500 usd in September and in October they will probably earn around 100 usd and in 6 months they will be in negative key me know

I will buy 4 units, not above 2k $, shipping must be in first week of August only to Pakistan , will pay directly to baikal

If you have free electricity it depends on how much kW you can use for free if you have like around 5 kW or more and have limited funds you can purchase s7 antminer to mine bitcoin they are very cheap around 500 $US to get and can give you around 200 $ US worth of bitcoin presuming that you have no electricity cost so it is worth while to have a bunch of S7

Hello is it viable to put 10 antminer l3+ on auto switch I will be getting them next month or shall I divide them some on fixed and some on auto switch thanks

I think litecoin and ethereum classic they will go 10× in 6 months

Is this really coin or just a scam any conclusion
