I am looking for Innosilicon A10 repair center in Europe. Anyone has an idea where I should send them?
Have tried asking the european repair shops listed at Zeusbtc website?

https://www.zeusbtc.com/RepairCenter/

I messaged them and I didn't have a reply after 1 month unfortunately.

3  Alternate cryptocurrencies / Mining (Altcoins) / Innosilicon A10 Pro+ 6G two hashboards not hashing on: October 12, 2021, 08:07:24 PM
Hello,

I have the following problem: One of my A10 Innosilicon suddenly the two boards are not hashing. I start the miner all three green lights from the boards light up green, and after that they stop. Up here everything is normal. After the miner finds IP and connects only one hashboard comes alive and becomes green. The other two never light green. I have checked also the dashboard and the miner doesn't show chain 1 and 2 and shows only number 3.

Here you can check the video ---> https://files.fm/f/xfbyemtc2






I have tried to reset it number of times and it didn't change anything. During the past when I had a similar problem it worked fine after a reset.

Do you have any ideas what I can do to fix this?


Thank you.

You are the man Smiley. Thanks a lot, crystal clear and concise.

Would you trouble to overclock them with immersion cooling? I understand that immersion has to come after 100th day since if I decide to sell there will be no value for them if they are immersed.

I think you mean the k version is bad not the j

From what I have read on other posts I think the same. S9 and j versions I think are ok, but I NotFuzzyWarm has a different experience.

Philipma1957 what is your view on the above questions as someone who has mining experience and knowledge?

Please read the various s9 support questions about the s9j -- it is a horrible version....

thank you for your answer. The S9j is a horrible version or both?
7  Bitcoin / Mining speculation / Antminer S9 questions and data on: February 24, 2021, 10:35:14 PM
Since the price of the new miners are ridiculous high I was thinking to buy 70-100 S9 Antminers  that I have sourced.
I have the following questions regarding the Antminers S9's:

1) What is considered a good price for the S9?
2) What is the most stable version? Is the 13.5 THz the 14THz S9J?
3) What is the life expectancy that see those miners will have, since the coming months there are tons of S19 and other modern technology miners arriving in the market and the current difficulty skyrocketing?
4) I have calculated the break even point at around 110 days in a price around $300 and the price of 0.06 cents. Does it make sense to purchase with that ROI?
5) Is there a trustworthy overclocking firmware? I have read all the relevant topics from the forum but I didn't found anything that seems trustworthy. Does is makes sense to immerse cool them?

Any other advice is highly appreciated and thank you in advance.

I am not an expert on solar panels but with some friends that we have researched on that, the problem is that you need power 24/365 per day and solar can not give it you. You need batteries to be able to store energy and have a much bigger solar panel installation to do so. That is why everyone goes near geothermal energy or hydroelectric because this can be constant supply.

Thank for your reply. Logical what you say.

As I understand to make a "safe" bet I will calculate the following 3 scenarios:

1) No mining difficulty increase for the next 2 years.
2) 50% increase for the next year and 60% for the next one.
3) 100% increase for the next year and 100% for the next one.

Does this sound logical?

I understand that this I very generic way to do it with many assumptions.

[...]

Thanks for your detailed answer. I understand completely the factors and the risk that you have mentioned but I need at least to make an educated guess , so I can base my scenarios on those guesses.
12  Bitcoin / Mining speculation / Re: 2021, time for a new general & diff speculation thread... on: February 13, 2021, 11:37:43 PM
The last days I am trying with some "home made" Excels to calculate the profitability of Cloud Mining vs Asic Mining for the BTC.
I am interested to see if it makes sense some offers that I have received for the first or the second scenario.
Difficulty however is the big unknown factor and it troubles me, how I should calculate it and what can be the worst case scenario about it.
To be able to calculate my difficulty scenarios, I have take as reference the difficulty for the previous 2 year and copy paste it so I can have a valid case.

The point that I would like some help are:
1) Do you believe that the above way is a proper way to calculate the difficulty? I have taken 2 years reference since the cloud contacts are for 2 years, and I believe also that after 2 years the Asics if I buy them will not have any sense to mine with them.
2) What is the worst case scenario that I should price in?
3) I know that all the Asic manufacturers are sold out until September - October next year. How this will affect difficulty? Do we know the capacity they have?


This thread I think is the right one to ask. I have read the terms of NotFuzzyFarm and I think it is ok. In case there is a need to delete it or relocate it just let me know.

Hello again, after a lot of search and calls and emails, I have managed to source some AMD 5700.
Do those cards worth to invest at a big quantity ? I am mostly interested for ETH mining.

Thank you again for your answers. I am not so sure the profit margins on the retail can be the same  or worse that wholesale. However it seems that you are right, since the story proves what you say.

What would be the possible solutions to this, for the retail hobbyist. Thinking loudly it might be no sense:

1) Group buys.
2) Cloud mining.
3) Form a DAO for mining.
4) ICO for mining.

Each of them has the pros and cons. Any other thoughts?
17  Bitcoin / Mining speculation / Re: Why all ASIC manufacturers are left out of stock? on: January 24, 2021, 10:00:52 AM
Thank you for your answer. I understand what you say. But I can not understand why they are selling to Riot and not to small clients when they can get much more money from the retail clients. Anyway from what I understand if you are interested for mining nowadays you have to pass through the resellers, which what they are asking is mad. Only if the prices double up makes sense to buy at those prices.

Also does anyone has an idea what is the MOQ to be considered as a "large" client?
18  Bitcoin / Mining speculation / Why all ASIC manufacturers are left out of stock? on: January 24, 2021, 03:19:15 AM
I wonder how is it possible all the Asic manufactures to have been for 2 months almost without a stock and if anyone has any information about it? I am thinking that with crazy market they should be selling 24/7 like hot bread. At least for whatever batch they can produce, something that is not happening and I can not understand the reason. Ok the silicon is rare and the companies who produce the chips have many more clients etc. But is it possible to be left so easily out of stock?

Also does anyone have heard something about when they will open their sales again?

Binance unfortunately offers it only in the FUTURES market and not in the spot.  The photo below is the order that you can give on Futures market on Binance and I want the same exactly but for spot. Do you have an idea which Exchange offers that for the spot market?

binance does offer them for spot trading, but you may not have noticed them. on the left of your trading panel there should be simple orders ("limit" and "market"). on the right, do you see a dropdown menu for advanced orders? that is where OCO should be located:



https://www.binance.com/au/support/faq/360032605831-How-to-Use-OCO-One-Cancels-the-Other-Order-Type

OCO it doesn't allow you to buy and put a stop loss and take profit at the same time unfortunately.

Have you tried FTX? The attached screenshot above is taken from their android mobile app, FTX Pro and it is available on Spot market and the same time Futures market too.
Ftx seems more complete since you can also see your % gain and % loss for take profit price and stop loss, this is also available on Futures market of Binance since you want for Spot market, you can try FTX.

Thank you for your answer. Tbh I didn't knew FTX. Is it a trustworthy exchange? Because I checked on coinmarketcap and it a has a ranking of 1.5 out 10.
