1  Bitcoin / Mining speculation / Re: Smaller PPLNS pools getting hammered by halving, rebound after? on: October 25, 2019, 12:18:35 AM
This thread makes me wonder if perhaps "mining pools" will end up undergoing something like what the hardware universe is seeing. The actual hardware mining is clearly moving towards an "industrial scale" in terms of the size of a miner, which has largely crushed the small "home" miner. Will there be a similar move towards "industrial" sized pools to survive?

I think it's time for me, and Searing, to think of ourselves as "coal miners" where we are being put out of work by the march to automation, or in this case "industrialization".

Maybe we should appeal to Bitmain to "End the war on home mining!"  Smiley
3  Bitcoin / Mining speculation / Re: Is mining gear efficiency a strong reason for difficulty increment? on: September 30, 2019, 07:39:11 PM
One small point. I think the whole small/home is rapidly evaporating. The only current (e,g, efficient) mining hardware comes in the form of a hot, loud, higher voltage (i.e. not 120V) box. With the exception of sidehack's efforts, there are NO highly efficient miners that exist at less than 25 TH, are there?

Remember when there was talk of "mining light bulbs", "mining routers", or mining "appliances"? Almost sounds funny doesn't it? As Phil said all Bitcoin mining is "industrial" in nature, and I don't see that trend changing in any significant way going forward.
4  Bitcoin / Mining speculation / Re: Gear Pricing just becomes more irrational then ever on: August 29, 2019, 03:22:24 PM
Think things will change much based on a recent BTC price of $9526/coin? I kinda wonder if there is now FOMO (Fear Of Missing Out) on the manufacturing side (not charging enough for new gear).

Where Crypto meets the "real" world, and not just currency exchange rates.
6  Bitcoin / Mining speculation / Re: Bitmain S9k not ready to ship. on: August 05, 2019, 06:04:46 PM
I am curious about how "new" any kind of S9 there are? Is there reason to believe that they are actually manufacturing any S9 models at this time?
7  Other / Meta / Am I the only one concerned about the KYC requirement here? on: April 01, 2019, 04:11:47 AM
I just observed the prompt about providing KYC (Know Your Customer) information to continue using the Forum here. While I am pretty sure I provided some personal information, SSN and/or Credit Card info is way over the line for me in terms of this kind of Forum. I get it for a bank where large amounts of money changes hand, but this feels way to intrusive, or perhaps the whole point of the forum is changing and I just didn't realize it.

It's rare for me to start a thread, but I wanted some other thoughts.

Would an air vent in the door be acceptable to the owner? It would seem less invasive and easy to replace in the future if needed.
9  Bitcoin / Mining speculation / Re: Will btc difficulty go sideways for rest of the year? on: November 27, 2018, 10:25:56 PM
Looks to me like the next change will be a definite decrease in difficulty. May essentially reset back to roughly the same difficulty as the end of July. This of course is all in the context of a big drop in BTC price (now roughly $3772).
10  Bitcoin / Mining speculation / Re: Will btc difficulty go sideways for rest of the year? on: November 24, 2018, 10:46:09 PM
For what it's worth, another step down in BTC price. Last quote from coinbase: $3757.
11  Economy / Service Discussion / It appears that bitcoinwisdom is back.... on: September 03, 2018, 08:23:32 AM
For quite a while, prior to the last "halving", bitcoinwisdom was my go to website to get a good summary of the state of Bitcoin mining, difficulty, profitability and so forth. It seemed to "leave the rails" and I stopped visiting it.

Just in the last 10 days, I have visited it again, and it appears to be pretty well straightened out. The figure look to be be pretty accurate and quite useful again.

Am I missing some massive flaw in it's reporting? What the consensus amongst other folks on the current usefulness of bitcoinwisdom at this time? Any back story on it's apparent "return"?
12  Bitcoin / Hardware / Re: My review of Avalon 841 . on: May 04, 2018, 07:04:02 AM
Until here is more complete info coming from Phil, or Canaan, I thought I would suggest an additional method for tweaking the A841 configuration. I am betting that it's possible to combine the avalon8-voltage-level value along with the avalon8-voltage-level-offset value. In other words, use the voltage-level value to make larger adjustments, and then use the voltage-level-offset value to bias it slightly from the value set by voltage-level. I have just set my A841 to voltage-level -1 and a voltage-level-offset of +1. This clearly works in that the miner starts and runs for me, and with only 15 minutes of run time, it seems a smidge warmer and faster than the voltage-level -1 alone, but clearly slower and cooler than voltage-level-offset -2 alone.

I don't have a good way to measure power at this time, so may not really be able to flesh out this experiment fully. It would be really attractive for Canaan to elaborate on the way in which voltage-level and voltage-level-offset interact with each other, and how that translates into power/hear/speed.

I am currently running the March 5th Pi software that was available when I got my A841. The MM firmware is what was installed when I received the box ( 8411802-1e73b80).

Thanks to all the folks here that got me past the "placebo" GUI option for Voltage Offset that didn't seem to have an effect at all.
13  Bitcoin / Mining speculation / Re: Intel Hardware Accelerator for Mining on: April 24, 2018, 07:57:48 AM
Color me skeptical.

A couple of years ago, a company called 21 Inc (became --> got a great deal of press in terms of Venture capital from big names. They also supposedly had some kind of "in" with Intel for chip fabrication. If the buzz from them had panned out, they would be a major player in terms of Bitcoin mining hardware.

Instead their one hardware product has been completely orphaned, and their current business model has no mention of Bitcoin mining chips nor Intel. Maybe all that they claimed was real, but Intel is a huge company and can "squander" tens of millions of dollars, and think very little of it. The last big thing with them could completely evaporate in a year. Intel knows where their bread and butter comes from, and as long as these little side adventures don't imperil the X86 business, they can make these "odd" investments without seriously impacting their business. Not so much with the companies Intel "partners" with.

Just my $.02 on where this might be going (or not).
14  Bitcoin / Mining support / AvalonMiner 841 not detected by Controller on: April 03, 2018, 10:09:46 PM
My experience with the Avalon 6 was that when the Pi couldn't see the miner, it is either:

1) The micro USB from the Pi to the AUC2 (for the A6).

2) The AUC itself.

3) The 5 pin cable from the AUC to the A6 miner.

On my A6, the AUC has a blue light with just a bit of flicker during normal run.

I know there is a way tell if the Pi can talk to the AUC, but I don't recall which log on the Pi tells you that. The GUI won't help, I needed to ssh into the Pi and look in /var/log/messages (maybe?). If/when I can look at this, I'll post additional debug steps. I don't know how a AUC behaves if it isn't flashed correctly.
15  Alternate cryptocurrencies / Mining (Altcoins) / Re: i have aquick question about the the Baikal Giant N on: April 03, 2018, 08:25:26 PM
Depending on the specific miner, you MIGHT find an option to "rotate" between 2 or more pools. What that might mean is to mine at one pool for N hours, and then switch to a different pool for N more hours.

Depending on the pools and their payout scheme(s), this might not work well at all. Some pools try to discourage "pool hopping" which is how this behavior would appear. This would be reflected in the payout scheme of thew pool(s).

At onew time I had my SP20 rigged so that it would switch to nicehash if there was a "very high" payment rate present for my 1Th of SHA-256 hashing. That was a long time ago. Long term, the market for SHA-256 hash rate is pretty open which keeps odd disparities from lasting too long.

I think has a mechanism for switching between BTC and BCH mining. This is a pooll option, and mot related to the mining hardware and it's associated software.
16  Alternate cryptocurrencies / Mining (Altcoins) / Re: Unboxing Acute Angle PC!New miner on: April 01, 2018, 07:50:14 PM
While it's a very stylish PC, it's just that. It's utterly useless as a Bitcoin miner. If your actual goal is to mine Bitcoins, you would have been far better off with a Raspberry Pi and one or more stick miners.

Sorry to be so harsh, but this is the wrong forum on getting help on booting a Windows 10 PC.
17  Bitcoin / Mining support / Re: Problem with the boot on: April 01, 2018, 07:45:09 PM
While I can't really help on your question, I can suggest that you "improve" your title to include that's related to an Antminer S4. As currently phrased, folks might ignore it thinking you are trying to boot a PC.... Smiley

Will you start a new thread for your A841 review and testing? Do you have an estimated ship date for your A841? Are you in the April 15th-April 30th batch that I see mentioned on the BlokForge website, or perhaps something sooner?

I am very interested in how this plays out, as you can probably tell by my questions.... Smiley
20  Bitcoin / Mining speculation / Re: I'm a little surprised the Network Hash Rate isn't Lower on: February 06, 2018, 09:48:54 AM
I kinda thought bandwagon, too.  Crikey.  20% increase since this thread started 6 hours ago.  That's something like 300,000 S9s.  Anybody notice the lights flickering?

What is the 20% that you are referring to? It's important to understand that there isn't some kind of "global hash rate meter".  Any website that provides an ESTIMATE of the current  hash rate is doing that based on recent block solve rate. In other words how quickly are blocks being solved. From that, the estimated hash rate is calculated. How many blocks to you use in that calculation? One, Ten, One Hundred? The difficulty adjustment is based on how long it took to solve 2016 blocks. During that interval, there can be wild swings, even if the final adjustment after 2016 blocks is quite small (even zero).

Of course there is new gear being switched on all the time. Stuff that was sold and just arrived (from Bitmain, Ebay, Bitfury, where ever) is going to get turned on. Nobody buys a miner and then doesn't switch it on for at least a while. It takes quite a while for miners, large or small, to turn off mining gear they have already paid for based strictly on BTC price.
