I'm tempted to buy one of these S5+ miners, but my lack of faith in Bitmain firmware is preventing me from doing so. I think I'll wait for the first batch to arrive with ~~guinea pigs~~ customers & see what the feedback is before making up my mind. Hopefully they have finally managed to find someone who knows how to write their firmware properly using the mainline cgminer instead of their terrible fork using crazy settings.

Fair enough as to waiting on the guinea pigs to report back on how these monsters behave in the wild ... though I'd take the notion that bitmain write terrible firmware for their rigs with a pinch of salt (last I checked the so called best ever cgminer never neither increased my earnings nor reduced my electric costs over the bitmain fork ... ever!). I'm just frustrated there is no alternative mining software for their rigs readily available .... and the noise from this beast of-course.

I went with bitmaintech's new hashnest offering instead

I got 10th for 6.66 btc.

Frankly I rather have this unit but the wife would kill me.

The price is good 2375 usd for 7.7 th

with shipping to usa 2473.37 keeps under that 2500 barrier. (thank you)

As for my choice of 10th for 6.66 btc

bitmaintech has sold 10,514 1th contracts for PACMIC v3 in the last 20 hours

that is about 7000 btc in sales.

It would be interesting to see what turns out to be the better buy.

phil, I cannot really get that pacmic stuff.
You pay for Th, then they will pay you until principal is paid, then they say the machine belong to them.
So, where is your profit?
Is today the first day and is there a pacmic thread?
Thanks

they pay two payments one is interest (your profit) one is contract payback.

it comes to about 12-14% per year. so 1 or 1.1 percent a month. my 6.66 btc should earn .21 btc profit in about 75 days. so in theory 6.66 btc will be 6.87 btc

I am getting 0.00006912 BTC/day (6912 satoshis) for one contract (1Th), which is equal to ~0.0021 BTC/mo per contract.
Hence, 10 contracts (10Th) will get someone 0.021 BTC/mo in "interest" on 6.66 btc spent.
Total expected interest on 6.66 BTC invested in 75 days (until the contracts are finished)=~0.051 BTC
As a result, i am getting a different interest rate than you.
What is wrong with my math?

pacmic: it looks like it gives you 69120 satoshis/day in bonus per Th (0.185/day or $5.5/mo). So, 10Th=$55/mo bonus, which comes down to ~1.8% interest.
They don't include the cost of mining, so it looks like contract will be paid off in ~73 days if difficulty increase is 1.57% on average.
So, you'll get ~$13 of BTC in bonuses per 10 TH (6.66 BTC), so investing ~6.7 BTC will get you 0.048 BTC in profit in ~73 days
The risk is that difficulty might increase faster and you never get your 6.66 BTC back completely

So we need to buy 3x PSUs to power this thing?

Or just two of these https://www.protact.net/netzteile/6/servernetzteil-mit-2.250-watt-und-12-pci-express-stromanschluessen?c=8 (I am guessing).

I don't think you can use only 2x PSUs. According to bitmain's product info

Quote

Do not connect more than one PSU to the same hashing board!

I don't see why not.
As I understand, there are 9 boards, just go 5/4.

Global economic crisis? i hold my bitcoin..

i hope someday my solo mining rig got a block, so i cant buy this miner Cheesy

this miner price is more than 30.000.000 in indonesian rupiah
with ship, tax and custom duties, it could be more than 40.000.000

my calculation, 3436watt is 120.000 idr in 24h
i assume that static diff, coins per day 0.07368986 = 273.000 idr, so the income is 153.000 per day
and 261,4379085 days to get roi Cheesy

Sorry, yes assumes static BTC/USD and difficulty, no-one knows on the former or the latter just gives a quick baseline to work from according to your own thinking and risk

Also assumes no halving? Since that one is semi-reasonably known (absolutely in block count, more fuzzy in date)

Nice to see it's a lot cheaper than the $3000 that was previously mentioned, updated spreadsheet

I think somebody inquired last time whether that takes into account the pending reward halving, and I believe you mentioned that you assumed a constant difficulty. Could you clarify the parameters you're using just for this thread

EDIT: The reward drop isn't for nearly a year so didn't see the point including that, some people will have import duty on top and maybe PSU's as well.

The 10x v3 should make around 0.105BTC?

I would guess the v3's unless your power cost is very low.

Couldn't resist at this price. It's been too long since I got a new miner.

Plus winter is coming; this 1 miner will heat 1/3 of my house. Hopefully it is not too loud in the basement.
