Topic: A2 A2MEGA 110,000KHs Scrypt Asic 1000w (Read 2707 times)

 Actually, Litecoin price kicked UP quite a bit when it halved, and has been pretty stable - and the hashrate has been pretty stable - since then.

 It's was a better situation for folks to have a good chance at RoI and even overall significant PROFIT on their gear than Bitcoin has since about mid-summer.


 This might change when the A4 is released, but depends on how many of those Innosilicon gets built and how long it takes them. A2 units will still be profitable even if the Litecoin hash rate doubles and the price drops back down to $3 (it's been above $3 since a month and change before the halfing) even if you don't have VERY VERY cheap electric.

 I actually wish I'd bought some A2s instead of the S5s and SP20 I bought last summer - they'd be a lot closer to being paid off, and I am having serious doubts about the S5's ever managing RoI at this point DESPITE the recent Bitcoin price runup (diff increases have negated most of that, and I was figuring on holding my Bitcoin 'till the halfing runup anyway).

 The 110 units I have work very well on VARDIF on liteguardian - the 88 for some reason doesn't (TONS of rejects) but it works well on their fixed 1500 diff ASIC server.
 I suspect the 88 needs updated software, but as long as it's working I'm not inclined to mess with it.


 The stock PSUs in these units ARE known to be very marginal - I highly recommend replaceing them with Seasonic X1250 (Gold) units (the EVGA 1300G2 will work but it does NOT fit anywhere nearly as well).



 P.S. - Scrypt got a hair MORE profitable between early 2015 before the halfing runup, and afterwards - the price kicked up from the $1something range (as I recall) to over $3, more than making up for the block reward halfing. It's doing MUCH better than Bitcoin has over the last year.

I did not change PSU (only dead).
But I have to set them on 1100MHz max.- rate aprox. 103MHash (on the pool a little bit under 100MHash).
Hash rate is stable.

By the way in last shipment (12 units A2 110MH -bought through our Chinese partner) were 4 PSU dead (!), so 30% defective...

Yes I think it's safe to say like that, nothing is certain specially with crypto coins.

I think it is best to say that general Scrypt mining just got at least 1/4 to 1/2 less profitable (depending on the coins you mine).

Will this change in the future?  Maybe.

I wouldn't make any crazy decisions until you give all this a month or two to determine the new baselines.

So you're saying LTC is doomed, just like after the halving, it's finish.... is that a fact or just purely specualtions?
So what happened to BTC after halving?
I think it's ok to speculate but to a certain degree only, unless you're a holder of huge volume, that you're definitely sure of LTC's future.

Still 2-4 for months ROI is possible.
From the day I invested in ASIC miners and from the day I get back my investment, I never touch my coins, I just took back what I invested and keep all the profit.
I treat my miners as the owner of those coins.
Now let's say my miners earn $1000/month and I buy a scrypt miner for $1200, how long will my investment return, you do the math?

PS: Just don't forget I never pay for electricity & never take a single penny from my pocket to buy an additional miner.
      If you still don't get it, I don't know what kind of logic you have.
      ROI depends on how "big or small" you invest, ROI is easy to get when you have an existing miners and don't pay for electricity.

Ethereum is decently profitable if you have a 500-600mh/s around $60 a day before electrity so $30-40 a day at 13cents /kwh

and with GPU's you can at least sell them for close to what you paid.

yeah lol thats what im trying to explain there wont be any ROI in 2-3 months unless the LTC price goes back up, multipools will be destroyed in the next few weeks since all the hash rate leaving LTC due to the halving has to go somewhere. 

Hardware prices are bound to drop which is why I think its stupid to buy now but its your funeral of course.  I have around six A2s and other assorted scrypt gear which I,m selling probbaly since I plan to turn it all off this week.

Hopefully i can find some suckers like you who will pay full price for hardware that is basically worth HALF what it was worth a day ago lol.

I have existing miners that have already ROI and I base my income in general not by individual
My miners are all self supporting they pay internet & buy an additional miners, literally speaking.

hitting the numbers on litecoinpool calculator payback is around 10 months even with free electricity how can you get 2 to 4 months ROI ?

btw what gpu mining is profitable now ? in nicehash they're not much better than scrypt IMO ?

Look man, there's no point in understanding to why people buy, we all have different situation, different circumstances.
Like mine, 1st I can't put up a GPU miner because looking for a shop that sells PC parts is hard specially I'm in the middle of nowhere
2nd, mining is just a passive income for me, I got a day job.

My plan is to buy miners as long as ROI will be just 2 to 4 months and keep it running 24/7

What about all the other alt coins that are Scrypt.  Lot of people mining them and making profit.

I'm just trying to understand why people do what they do, looking for a reason
As to why ppl are buying scrypt hardware when its not even profitable and its about to get even worse

I can understand if you already had some hardware or prices were better

I mine both BTC for now
I want to try out LTC, hopefully soon I'll be mining both BTC & LTC.

You mean you've change all the stock PSU? that sucks!
Are the hash rate stable?

I would hope that people aren't just mining LTC.  How boring and unprofitable.

All right captain marvell1, I wouldn't argue, I just don't know whats your point with people asking input and reviews with scrypt miners (scratching head). do you own or hold a large volume of LTC, do you belong to a group of big investor of LTC, otherwise if not then you're just speculating with the upcoming LTC halving  

PS: I was asking for inputs, reviews and not sarcasm.

Cheers captain marvell!

I had aprox. 30 units A2 Terminators. They work good, but they are some problems with quality 110MHash version (6 boards/10chips). Usually they are not new, but used (dusty fans, rusty screws), various fans inside, bad quality and insufficient PSU (usually noname only 1000W, but it need 1200W for mining 110MHash - 1200MHz frequency).
Also their consumption differ - older/longer boards inside consume aprox. 100W less than newer boards V3 and V4.

Lol i said nothing about stealing electricity , nothing is free though , somebody (im sure its not you)  paid a pretty penny for those generators and is paying for the gas they are burning.  Nothing is free in this world belive dat.

And btw captain obvious of course you are profitable mining ANYTHING with free electricity that goes withoute saying I i'll spell it out for you since you cant seem to comprehend what I am trying to tell you :

BITCION or GPU mining is currently more profitable than Scrypt mining due to LTC block halving simple as that its s dumb time to pay a premium for Scrpt gear right now since prices for this hardware is sure to drop significantly in the next few weeks , i think by at least 20-30%.   

You're wrong again my friend, If you think I'm stealing electricity, then you are mistaken, I live in  big camp located in the middle of the desert, now our camp have 5 1000 kva generators, imagine that power plant.

I don't think you've experience mining with free electricity, believe me either your mining with sha256, scrypt or gpu, all of them are still profitable, I'll say it again free electricity is free BTC, LTC etc. etc.

Your situation & experience maybe different from mine, you pay, I don't! pure profit 24/7 365 days 

Good luck to your gpu mining Marvell1,

Cheers!

I don't believe in free electricity , even if you think your electricity is free somebody downstream is paying for it

any im not questioning the judgement of people buying MINING hardware in general , its the fact that they are buying SCRYPT mining hardware ... right now even GPU mining is more profitable than scrypt free electricity or not.

If anything buying an S5+ will provide more profit than an A2 or any kind of scrypt miner with LTC going into the crapper.
