Bitmain's support SUCKS big time !!!

I received the S5+ (7.7T SUPPOSEDLY) at the beginning of September and I immediately opened a support ticket (5th of Sep.) because the results I got with the miner were AWFUL !
I was waiting for 10+ days for a single reply, and each time their reply was asking me "did you do this, did you do that" although I explained in details what I've done, so they were obviously just stalling.
This took like 3 months of Q & A , going into circle with the same questions over and over , to finally notice that beginning December they CLOSED the ticket like it's been solved!!! I re-opened the ticket 10 days ago - and guess what - NO reply yet !!!

They didn't offer ANY solution for the whole time !!!
They tried to put the blame on the PSU's, so I bought 3 new 1600w PSU's !!! For nothing !!!
I'm still getting like more than 70.000 HW errors per day showing 6.5T at the max Angry

THE WORST COMPANY WITH THE WORST SUPPORT !!! *E*V*E*R* ! ! !

A simple question what is your freq setting?

sorry didn't pay too much attention to what happens with halving in relation too litecoin.

so with bitcoin does the difficulty halve too. My S% really struggles with the difficulty at 79+

The immediate impact of the "halving" on difficulty will be zero. Difficulty is determined by the rate at which blocks are solved. not how many bitcoins are produced. The INCOME is what gets halved, not the production of blocks.

Obviously that will impact some folks more than other. If enough gear gets turn off as a result of the reduced income, THEN (and only then), will difficulty fall. Also it will take quite a while for difficulty to fall. It's only when the 2016 blocks take more than 14 days to solve that difficulty will fall.

The difficulty mechanism is quite unlike any other industrial operation we are familiar with.

What I want to see is a U4 with 4x BM1385 chips in it, the S7 is nice but too expensive for a lot of home users.

12 chips.

The difficulty did not and will not halve. At the moment all my antminers are doing great. Even my S1's are profitable at peak electricity cost right now. Hard to complain.

Yes, most folks on this forum would love to see the BM1385 chip used in something much smaller scale than the S7 (i.e. fewer chips, fewer boards, etc), but so far Bitmain is still pushing variants of the S7at 1100W+.

My feeling is that they are concerned about the impact that the halving will have on the appetite for hash (i.e.new mining hardware sales), and they want to sell as much as they can at a hefty price.

yeah, this miner is overpriced. the hardware inside is worth 1000 bucks. 1 TH has the same price as late 2014 but the difficulty rised in that time and in 7 months is the halving, so, not the best deal for us, good one for badmain is guess.

You are a little bit behind time here. The BM1385 has been shipping for several Months in 8 Batches now, several threads on the Forum covering the S7.

With free electricity, no difficulty increase, the ROI time is next year in March. Not particularly "in no time" for me. With 0.08 Electricity and 2% increment, you will never break even. Your only strategy for ROI would be to mine it for a bit and then sell it before it devalues.

DEPENDS ON THE VALUE OF BTC!

Wouldn't it be much better if you just purchase btc and save yourself of the risk of not breaking even + noise + psu + wire + heat?

But where is the fun in that?!! Grin

Well you know, if your plan is betting on BTC to raise 20%, you might as well just hodl that 8BTC and i'm pretty sure this result in higher ROI than mining with it under those conditions, but hey, what would i know? I don't hodl. Tongue

The fun is in watching your PROFITS roll in while laughing at folks spending tons of money on a miner they're going to LOSE money on if they don't have very cheap electric?

AKA the fun of WINNING?

When my first batch of s7's come in I will mine and wait around two months to see what happens to the market when all of the big mines start upgrading. If the swing isn't too much I will buy my second batch of s7's or s7+'s(?) and mine a month or two up to the halving. The increase in difficulty isn't concerning me as much as how volatile the market will be leading up to the halving. Depending on the market I will likely sell all of my s7 or s7+s and day trade for a few months.

I pay .085 cents per kWh, so with the difficulty my ROI would be thirteen or fourteen months including almost all overhead at current btc prices, but with eighteen s7's I hope to make one last timed jump out of the mining and sell the s7's. If the specs on the next gen gear are accurate I don't see my continued involvement with mining at all since it will be easier to make coins on the market swings. I see the days ahead of buying coins instead of mining and trading them. Sad

I'm saving most of my earnings to get my hands on the new Antminer S7. The best thing about this miner is energy efficiency so I would save money and reach ROI in no time. This has been added to my wishlist. I think I'll be selling my good old Gridseed GC3355 to earn some extra cash Roll Eyes

What is your electricity price? I don't think of reaching ROI in "no time" happens much anymore.

It's kinda a long game that takes a while. I miss the 90 day ROI time, now it's in hundreds of days.

I think it is $0.08 per kwh. I’m not so sure because usually my parents pay the electricity, but sometimes when I consume a lot of energy, I have to pay it. Still, the less energy consumed the better. Roll Eyes

That’s fine. I’ll just mine for a few hours (not 24/7) until the difficulty increases. Later on, I would sell the miner and hopefully buy a better one (when time comes) Grin

It would take me 6 months to ROI with an S7 here if diff and BTC stayed at current Sad

Power is 22.3 cents per KWh in NZ...

Hosted @ 10 cents per kwh or cheaper it would be viable though.. hmm

22.3 cents per kWh Shocked
