Antminer A3 : 815GH on Blake(2b)

The real shadiness is the company behind Sia presold ASIC miners that won’t ship for six months, lol. Those people won’t be getting refunds and their miners will likely never ROI because they are shipping so long after Ant:

I don't think they were shady so much as just in over their heads. Not giving refunds is pretty lame though.

Those also mine decree apparently. So while sia might not be profitable. Perhaps decred might still be.

Well technically there is no they yet since they're still vapor. Who knows if they even bother having the Obelisks manufactured since there won't be any meat left on the bone after Bitmain releases additional batches.
 
IT MIGHT just be that nearly all the first batch of antminers have been put on the network at this point. Look at the global hashrate strong increase tapering off.

(sea green is global network hashrate)

I suppose we might see another slide up early next week as package carriers begin delivery again during the work week???

Is there like a month or so between shipping batches from Bitmain?

If that's the case, then the first batch guys will be able to make some good $$$.. You are still at 100$/day right Archaea ?
 
So you have about a month to break even, if the hashrate & diff stays the same. That's not bad. =)
 
all the sudden I'm seeing a bunch of discarded blocks. Are you guys seeing that - those of you with A3's?

I've rebooted twice and switched from east to west siamining pool - same thing like nearly 2/3's of my submissions are discarded.

nethash rate is still climbing just not a quickly as it was. think someone looked at the BCH wallet address for the sale and estimated about 13k A3's sold assuming all the BCH was for A3's but there was no other sale going on so.
 
Surely this isn't right? Discarded

but my hash rate seems a little higher than even expected?

Bitmain released the batch 2 on Jan 29, 2018 at $980?


The first batch was $2375 + $170 PSU + 73 Import tax + (whatever expense you paid in converting your currency to BCH).

I was first batch. I setup my miner Friday within 30 minutes of taking delivery it was mining. Today, currently on Monday I've mined 5270 SIA coins. At 4 cents a coin that's $210.

Current profitability is down to about $44 a day. It'll drop hard next week when batch 2 comes online.

Basically I'll consider myself REALLY lucky if I ever ROI on this. Looks like 6foot4geek had the right idea to sell it upon receipt. This is probably my first and last ASIC venture. Just way too much risk.

Ouch. $44 a day and still another batch to go..... OK, I am glad I did not decide to get one.

Overall I’d be more concerned with the shit show that the developers are talking about in Reddit. They are talking about building a decentralized exhange with $500,000 instead of developing the coin, getting it on more exchanges, or working to integrate their storage solution into more businesses (like Storj has done). Sia will be worthless with misguided developers. The floor could fall out of the currency if people catch on.

I mined ltc back in the day and bought some of the gridseed asic miners. Same thing happened, made roi and a little more, but it was a pretty close call and enough to make me never consider it again. I use them as coasters now lol
 
Sorry to hear it bro. I can see why Bitmain wanted to get paid only in crypto and didn't accept visa/mc/amex cuz charge-backs would happen.

Okay - I read more at reddit. Apparently Batch 2 went on sale today, but doesn't ship till March 15. That's a lot more reasonable for batch 1 purchasers. I assumed it would ship in 10 days like batch 1. If hashing rate stays around $30-$40 a day until say March 20 - that at least means another $1500 in mining profits ($30 x 50days). So I'd be sitting at about $1700 in sia coin. Not $3k, but not making an outright bloodbath either. With that in mind it still should ROI within the year if profits then dropped to $10 a day for a few months before they went to nill -- but it's certainly not the golden goose I hoped it might be.
 
I think Bitmain has done the maths on the ROI and are pricing the batches around the ROI. So whatever they sell Batch 2 at expect that to be the ROI from the delivery point till end of life. So if Batch 2 is selling for $980 and you expect to make $1500 in profit by the time Batch 2 is shipped then that just covers your ROI from batch 1.

Good gig for Bitmain to sell the machines for what they will make and not have to bother with the mining aka the power, heat and the noise.

Yeah I wasn't sure why you were sweating it when I glanced at this yesterday, but you'll be fine assuming Batch 2 doesn't ship earlier than March -and- Bitmain doesn't allow any china-only partners to crush ROI with units that aren't part of the known installbase - which I'd assume they'd be too smart for since they've executed everything else perfectly.

If it were me, and assuming you & your lady can tolerate the noise envelope, I'd probably keep a standing ebay & CL listing up for $4499 for the thing, and then keep reducing it gradually as the ship date for the second batch approaches.

Oh yes. Their execution on their Sia invasion was perfect. I'll point out again that Bitmain doesn't get high off their own supply and mine with their own hardware because they don't need to - selling an ASICminer is an insta-mine where they get the total ROI all upfront.

Why does it looks like the network hashrate is steadily going down? (how is that possible with more ASICs coming online?) Would that be the GPU users that are dropping off dual mining with ETH, or even solo mining SIA?

^^ Hell i woulda been gone 3 weeks ago from mining out anything on SAI.

asics are always that way. either get in first or don't get in at all.

so from the recent rise in hash it looks like new batch of miners are up and running?

how's ROI? daily profit looks unbelievably terrible now!

I sold mine on the 24th of Feb for $2500 to a local guy off craigslist. I told him all about the decreasing value, and was perfectly frank with him, and he still offered me $2.5K.

He's long on siacoin, he was also buying some of the march batch of A3's. Difficulty hasn't increased that much really. Just sia coin value has dropped more than anything.

These would be his stats today. ($20ish a day right now)

------- for my part

I ended up with 47,000 sia coins for about $300 + electricity cost (which was about $2 a day, and since I had it for just shy of a month - let's say it was $50 for electricity) So I got 47,000 sia coins for about $350. (I bought about $80 worth of sound deading materials to quiet that thing down that I just gave the buyer) -- so really lets go with $430. If I sold my SIA Coin RIGHT now I'd just basically break even.

I've just been holding the coins as they devalue though. I've held them from 3 cents a coin down to 1.2 cent a coin. I guess I'll probably just hold them in case they go up significantly in the next crypto pump. :confused:

Heck, if they hit a dollar a coin (super unlikely) - that'd be alright with me. I put it towards my house mortgage straight away!
 
I have a problem with the brand new A3 miner. The fans power on, but there is no green nor red light, there is no IP, reset button doesn't work...I cannot do anything with it...is it a control panel malfunction or what? I tried everything including flashing via SD card and nothing helped. Help anyone who can

Sounds like the controller isn’t getting power.

Swap the pci-e connection that is a single to one of the other 9 power slots and see what happens

What PSU

what voltage?

220V, APW3++ PSU. I dont think it is a power thing, the control board has a red light, but control lights (green or red) are never on, nor can I reset it, nor can I find it's IP adress. Basically like it is working on idle...have no clue what to think of it. Tried shuffling power slots but nothing
 
Mine was never 'on idle'

first gen batch powered up full when you plugged them in -- mining to bitmain's wallet.

You should open a support ticket. I've heard their customer service is actually surprisingly good.

I opened already...got answers like restart etc....nothing useful. Have no idea what to do....to send it back on my expense makes no sence since sending back is expensive and also there are customs problems...unless I make it work I can just throw it away
 
Here is my question: How did bitmain know the future? This is starting to sound similar to inside trading, only the customers get screwed! hummm.....

No one got screwed. They got what they paid for and everyone knows ASIC mining is a harsh game of depreciating profits.
 
Antminer A3 is now only $520 USD on Bitmain's site.

https://shop.bitmain.com/

There's competition coming out though with several other Asics. Right now they are making about $12 a day net or $15 gross -- because of the recent crypto resurgence and sia coin value jump. Which at current price is a pay off of about 45 days. (though it won't be that fast a payoff for long as difficulty will continue to spike)
