[NEW] Bitmain Announces Antminer A3

[BitcoinIntern]

Thanks for getting back. I do have a hot and cold aisle set up and have been really scratching my head to figure out how much is just too hot for these. Have you run these in your basement throughout the summer? I mean the other kinds like S9 and other bitmain miners during the last summer?

Yes I have and my setup before was nowhere as clean as it is now. The s9's would run up to 75C in a messier setup then what I currently have even with fresh 90F air flowing in so I'm really wondering how the A3's will run during the summer. I might need to run all my miners at 2/3rd default clock settings.

Thanks...so just fresh air does the trick of cooling these miners? I have been asking around on ideas to keep these cool during the summer but the large miners here haven't been responding. I am surprised that the 90F air was keeping the S9's cool at 75C. How many were you running at each time? Did you have any which stopped because of high temps?

Spectacular pump of Siacoin!!!.

with climb you mean pump

Yes!. Climb?, what climb?, ;-).

25% increase in less than 10 hours is considered a pump

Yep.  Keeping an eye on it.  Batch1 A3s are close to ROI levels if you hodl'ed all coin.

I got my initial investment long time ago ethereum wise. I paid around 2.9 ether for batch 1 A3 and a power supply when ether was $1000. Now I have around 4.8 Ether or $3192.

Hi, do you know why this huge increase in difficulty and network hashrate?. I suppose it will be due to the arrival of the new Obelisk miners and the Halong Mining Dragon Mint. It is right?.

Regards.

According to siaming stats the difficulty rised more than the hashpower of the network.Strage behaviour.Maybe the siacoin dev team don't want to have much coins out there now that they rised in price.

I'm thinking of buying an Antminer A3. Do you think that it will continue to be profitable for a few months?.

I think as long as the price of SC holding at the current price, it would be still profitable and easy to ROI.
According to Siamining.com,  miners are paid about 0.55 SC/day per GH/s.
With the InnoSilicone S11/A3 bactch 3 and SC1 miners coming in the next a few weeks. I am expecting the rate decreased to 0.3-0.35 SC/day per GH/s
The expected ROI is about 50 days for an A3.

Thanks you very much!.

Although I guess it will depend on the electricity expense. In my case, very high, about 0.17 USD Kw/h.

Best regards.

Make sure to use the coupon when making purchase.
I used a $100 coupon but I think it allows to use a $200 coupon for A3.

Great!, thanks you!.

But, I believe that the ROI you have calculated is not right. For example, 0.35 SC/day per GH/s is about 285 SC x 0.028 USD = 7.98 USD per day. That is about 240 USD per month and you have to subtract the electricity, which can be about 150 USD per month (in my case). Then, there would be an approximate profit of about 100 USD per month. This gives about 5-6 months of ROI.

Best regards.

Yes, you are correct in your case. I have a slightly different situation.
I am overclocking the A3s, so each provides ~935GH, and the electricity rate is ultra low in my area (less than 4 Cents  in USD), and I am not selling at this price, instead I am hodling all the time. But I agree that 50 days of ROI might be an overly optimistic calculation , though.

Difficulty rises very quickly:  calculator now shows that you can earn $175 a month with today's difficulty, which is far more than 50 days...

thats not much..

Assuming an electrical cost of $0.04/kWh and power consumption of 1275W as listed by Bitmain on 220V with an APW3++, you're not even going to make $150/month now, and most people will make less than that with an electrical rate of $0.10/kWh (~$90 currently). There's just no way that you're going to break even in 50 days, even if you're not limited by electrical costs. It's simply not possible, and calculators do not factor in difficulty for the future which makes everything worse.
