If you want to be a merit source:
1. Be a somewhat established member.
2. Collect TEN posts written in the last couple of months by other people that have not received nearly enough merit for how good they are, and post quotes for them all in a new Meta thread. The point of this is to demonstrate your ability to give out merit usefully.
3. We will take a look at your history and maybe make you a source.

I am applying to be a merit source.
My focus would be mainly on the altcoin section:
   I would run a promotion to try to get people who have sent little or no merit to start using it
   I spend time in some of the mega threads, there are under merited posts buried inside
   I mine Bitcoin and Altcoin, and appreciate the hardware side

These are some of the posts I believe could use more merit:

KYC is for banks and official institutes not for ICO which any random online can start. It's data harvesting and I for one refuse to just hand over my personal info to some random online. No wonder people us fake ID. I could see this was going to happen a mile away. KYC is useless online. Proper KYC is like when you open a bank account. You go in and actually meet a bank representative and not just trust some online only organization. You then sign legal documents and submit your ID and proof of residency in form of your electricity bill for example. This can't be faked and your info cannot be shared or you can sue the bank and win.
Let me make this clear. I have no issue in using KYC when it is fully legal and sanctioned. But I will never hand over a KYC when I can't meet the person asking for it. If you investing large amounts of money you should meet face to face with the people behind the ICO anyway. I don't see why anyone would give money to someone online and then still give them their identity. There is no reason for an ICO to ask for KYC and they are just making excuses as to why they ask for it. It has nothing to do with tax. You must fill your own tax form every year end yourself and declair your expenses and your profits.

How long will it take till criminals decide to use an ICO and harvest our personal info and steal our identity? You will be relaxing having a good Sunday afternoon when suddenly a police man knocks on your door and wants to talk about crimes committed under your name. Identity theft is serious and a problem in every country. Stealing someone's identity is like free money because they can abuse your identity to take loans and all sorts of things under your name and your identity.
In my country if I steal someone's identity I can do all sorts of bad things. I can open cellphone contracts and contracts with shops and buy video game consoles tv sets and even furniture all under the name of the person I stole the identity from. I could run scams and use your identity and then you get harrassed and stalked online because people think you ran the scam. (Please not I am not an actual criminal I'm just saying if I were one what power having your identity would give me)

People please think before just giving out your personal info. Think about your safety and the safety of your loved ones. Your family love under the same roof as you do and now how many icos know where you live? Just knowing that, that many people know where I live makes my skin crawl.

So please people don't give your KYC because some nitwit online promises to pay you. Even if you are paid it means nothing. Your info can still be abused and there is very little you can do about it since you handed it over willingly. You have no legal protection at all. I don't even think it's legally bound to be honest.

What criteria do these KYC corporations use? I mean the info they use must be public correct? So if everyone has access to the same information as they do the entire premise of KYC seems to be a sham. I almost sent mine in for Polymath. Thank god better judgement prevailed.

Their person info should be public if they plan to ask for KYC. After all you won't give your KYC if they won't give theirs right?
You are correct.

It seems as though the community was willing to give up the key principle of crypto (privacy) and the process they submitted to wasn't even legit with seemingly a large portion of the people simply sending in fake docs. I personally boycott all projects asking for KYC so my information is safe however crypto is in major trouble if we have swarms of people willing to give up their data for a few bucks. The people who put profit before the movement are despicable and we and our ancestors will continue living in monetary slavery to the elite do to their greed. Great job guys and thumbs up to everyone who crashes this KYC process. Modern day heroes in my book.

Good for you. I name and shame any ico asking for KYC. Another tactic is as we saw with casinos not paying out till you show KYC the ICO will not pay bounty if no KYC is shown. This is theft because they dent payment.

Quote from: funnelz on February 19, 2018, 12:04:14 AM

Send in no real data for KYC. Don't use a real person so no ones identity was stolen. Be from a backwards country.

Do you think they know the complete information from an individual living in a remote part of the world? Give me a break.

Way more risky to send in the real thing. At that point your legal troubles could be Murder, Terrorism, Hijacking, kidnapping etc.

Not many people in jail for claiming they are from the Democratic Republic of the Congo. Good luck finding information on Mr. Migushu. They will simply pass it. You all see what a complete cluster fuck the KYC turns into right? Do you honestly think it was running correctly? Was everything top notch and smooth. Nope its a complete cluster f*ck.

Exactly! People can perform criminal acts under your name.

Quote from: edwardnortonn on February 18, 2018, 11:44:35 PM

One of the main reasons why Cryptocurrencies is famous and preferred is the fact that it provides anonymity. the documents such as passport and ID, required during verification already goes against one of the integral features of the trading platform,However sending fake ID for KYC seems to be a loophole hackers are exploiting. it also leave s a big concern of=n the security of the users accounts,

I share the same worry, KYC might be the blueprint for the fall of crypto currency.

Exactly!! Crypro is ment to be anonymous. It's like using a VPN but for money. The government already has so much control. We are not criminals we are simply people who want control of their own money.

Very low maintenance, ever since I added automatic restart scripts on a 24 hour interval and watchdog scripts to restart and log automatically whenever it notices 0% GPU use or network disconnection. I take a little hit while it restarts though.

Care to share more about these scripts? I'd find that very helpful. Thanks!

I have a script called autoexec.cmd start on logon using the Task Scheduler. Autoexec.cmd is a little take on the good times of the past. It will start the miner program and watchdog. I choose the miner program I want to use by commenting out the others using the REM command. After it has started the miner, it will run C:\Tools\watchdog.cmd which will start monitoring that the system is on the network and the GPU's are doing meaningful work. The Autoexec.cmd script will then hibernate (but still stay running) for 24 hours before it restarts the system. All this while watchdog is on another command line session monitoring the system.

I've written these scripts to work on Nvidia mining rigs. They can be freely copied and modified as needed.

C:\Tools\autoexec.cmd

Code:

@echo off
echo .---------------------.
echo / INIT SYSTEM SCRIPT /
echo *=====================*
echo.
echo %COMPUTERNAME%
echo.
echo Waiting for WIFI to wake up...
timeout 11

REM -----------------------

echo Time before restart: 5 mins

echo Restarting now!

shutdown /r

Below is a (VERY CRUDE! )

script that logs every bootup and tries to ping preconfigured IP addresses 8.8.4.4 or 8.8.8.8 every 30 minutes. It will also use the NVIDIA configuration utility that comes with drivers called "nvidia-smi.exe" which tells the watchdog if any GPU is at 0% use. It will try a couple of times and restart if any GPU stays at 0%. Any errors that occur it logs. It's a bit botched together, but works great in my use.

C:\Tools\watchdog.cmd

The below example script will set the overclock settings for 5x GTX 1060 graphics cards on the console using nvidia profile inspector. It is called from autoexec.cmd, so that the overclock settings are set at boot time. Same functionality can be achieved with Nvidia Afterburner, but one of the Nicehash miners would override/reset my OC settings, so I started using scripts instead. Additional bonus is, that I can run these in a timed loop every hour to "remind" the miner computer of the correct OC settings.

oc_zec_effic.cmd

Code:

@echo off
echo OC: ZCash mining (max efficiency)
echo.

Hello All,

Just wanted to share my funny experience with these cards I purchased around a year ago.

The cards Im talking about are the Gigabyte RX 570 Gaming 4G: https://www.gigabyte.com/Graphics-Card/GV-RX570GAMING-4GD#kf
They are pretty much the worst cards I got for mining, even though I bought them early on for 160$ each, and I got 30 of them.
At first they were great, amazing value for money and ROI, elpida memory, they do 29.5mh/850mh eth/dcr; and 900 h/s on cryptonight.

They worked great for 10 months, and then the fans started failing; these fans can not handle dust at all. They are very poor in cooling; and unless I set the fans at 80% or more, the gpu temps would easily reach 75C.

The funny thing is that half of my cards would have the rear fan failing, either completely stop working, or work at a much slower rpm; to the point that I had to only mine cryptonight due to the lower power requirement for the algorithm compare to dual mining.

So I got this idea..

A week ago, I purchased these fans: https://www.aliexpress.com/item/Brand-Original-Delta-AUB0812VH-pwm-DC12V-0-41A-80mm-computer-cpu-case-axial-cooling-fan/32541022969.html?spm=a2g0s.9042311.0.0.Fy7LDH
And these splitters: https://www.aliexpress.com/item/SATA-Port-to-10-Way-12V-3-4Pin-Computer-CPU-Cooling-Fan-Splitter-Hub-with-PWM/32842778420.html?spm=a2g0s.9042311.0.0.Fy7LDH

Removed the shroud and fans from the gpu, and stuck the new delta fans I got on the heatsink (using some metal wires, and a bit of clamping).
and this is the result
https://image.ibb.co/hSBvY7/IMG_20180213_WA0006.jpg

Currently, out of all the cards I have; Nitro+ Limited Edition, XFX GTS Edition, Nitro+ 570 8GB, and Powercolor Red Dragon golden sample; these cheap elpida cards are my favorite xD

Temps on the gpu are at around 39C under the same conditions, and they consume less power (compared to the original fans, 12v @0.5A, the new ones are 12v @0.41A).

So I lose the warranty, but I've already recovered their cost and much more, and they still run perfectly, so I am very happy Cheesy

Now im thinking to do the same for all my other cards, and probably turn one of the AC units I got off to save on electricity

I thought I'd share this with everyone since I think this is a problem we can all relate to. While it would be nice to have a networked PDU, they are quite expensive... even on the used market. So I thought about it and came up with this solution.

I'm sure we all have a rig or two where it may work fine, but every now and then it needs to be rebooted. It always seems to happen at the worst of times... like when you are at work... or out of town. Trying to get your spouse to reset a rig over the phone can sometimes be just as frustrating as when you are away and can't do anything about it.

I also use Awesome Miner, which is fantastic, and can do a lot of automation to keep your rigs running. But if your rigs need a hard reboot, the only real solution is to "pull the plug" and reboot. Awesome Miner has "rules" that you can define to watch for triggers like an offline miner, hashrate thresholds, dead GPUs, and a lot more... and then perform an action. It's kind of like an IFTTT (IF This Then That) solution for mining.

IFTTT... hey wait a minute... I could use the online service IFTTT to control a smart plug. I could have Awesome Miner watch for some condition, then send a signal to IFTTT, where in turn IFTTT could turn off and then on a smart plug.

I started out with a Wemo Insight smart plug that I had laying around, and after a bit of tweaking, I got this working well. The problem is that the Wemo Insight smart plug is only rated for 120V, and all of my miners run off of my 24 amp 220V PDU that I got for real cheap off Ebay. I then trolled around to find some cheaper parts to do a 220V equivalent to the Wemo Insight smart plug.

Puwaha's Poor Man's Networked Power Distribution Unit
(or PPMNPDU... nevermind, that's a bad acronym)

Parts you'll need:

Cheap 220V PDU from Ebay (I'll let you find these to suit your liking. You could even do this with 120V PDUs)
Cheapo 240V capable Smart Plugs like these at Amazon (https://www.amazon.com/gp/product/B078CPYQYS/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
)
My PDU uses C14 connectors, and the Smart Plugs are 5-15P, so you'll need some good C14 to 5-15R adaptors like these at Amazon (https://www.amazon.com/gp/product/B004OC579E/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Good quality 5-15P to C13 power cables. These are your regular power cables that come with every power supply you've ever bought... you probably already have a few... so free!
IFTTT account (it's free)
Smart phone to setup the smart plugs (Smart Life app, and IFTTT app)... not free, but you probably already have one... so free
Awesome Miner... it's free for up to two "miners" to give it a go, but easily worth the license cost in other feature you need to cover all your miners

Note: if your setup requires the C14 to 5-15R adapters, do not get the crappy 18AWG 1 foot "monitor extensions".
The wires are not meant to carry high amperage that your rigs usually require.

Now, to put it all together.

First thing, go setup an IFTTT account. You'll need that before integrating with Smart Life.

Let's go ahead and setup your first Smart Plug. If you didn't pick the ones I did above in the Amazon link, just make sure they are compatible with the Smart Life app. This is pretty simple to setup. I suggest you do them one at a time so you can mark them with a pen, and edit the entry in the Smart Life app... like "Plug 1", and "Plug 2".

After setting up the Smart Plug in Smart Life, give it a few whacks to make sure you can turn it off and on. In the Smart Life app go to Profile settings and click Integration. Select IFTTT, and it will give you further instructions on how to integrate. You'll need to sign in using your Smart Life account to integrate. You can either use the IFTTT app on your smartphone, or the IFTTT web page... same results.

It's time to build the first IFTTT applet. Go to your IFTTT app or webpage and click on "My Applets", then "New Applet". You are now going to setup a trigger (the "This" in IFTTT), and then an action (the "That" in IFTTT). Click on the +this logo... you will need to choose a service. Type email in the search area and then click on the email logo. Choose the "Send IFTTT an email tagged" option. We want the tagged option, you'll see why in just a second. This trigger will kick off when you send an email to the trigger@applet.ifttt.com with the tag that you supply. Our first trigger we will setup will be #plug1off so put that in the field where it says tag, then click create trigger.

Now, we need to add an action to the applet... so click on the word +that logo. Now search for Smart Life, and then click the Smart Life icon. You'll see a couple of options to turn a device or group on, and another to turn a device or group off. If you think about that for a moment, you may realize that you can group smart plugs together in the Smart Life app on your phone, so you could control multiple plugs with some of these steps. But for now, we will just finish setting up the applet for our first smart plug. Since our trigger tag was #plug1off, then we need to click on the option to turn a device off. IFTTT then will present you with your drop down list of Smart Plugs that you setup in the Smart Life app. Since this is our first one, we will select Plug 1 and click the create action button. Finally, click the finish button, and you've just created your first applet in IFTTT! Make sure it's turned on.

Repeat setting up a new applet in IFTTT, use the same trigger of "email" and use a new tag called #plug1on, and an action from Smart Life to turn on a device or group. Select your Plug 1 device and finish the applet steps.

If you've never used Awesome Miner before, the bare minimums you need here are a pool, a managed miner, and a rig. Once your rig is being controlled by Awesome Miner, you can automate it with a new user-defined rule. There are some built-in rules to give you some ideas of what you can do, but for our networked PDU concept, we will create a new one. First, go into the Options, and under the Rules section go to the Email & SMS section. You'd want to setup your email account here anyway, for notifications from Awesome Miner in general, but the most important part is that you use the same email account that you used to setup your IFTTT account.

You see, the IFTTT applets you created are expecting an email from your email account. If you use the same email account in Awesome Miner, then when you setup the user-defined rule to send an email... it matches... and the trigger is set.

Now that you have Awesome Miner setup to use your email account, go to the Rules section in the Options in Awesome Miner.

You'll give it a fancy name like Plug 1 Reset. If you have more than one rig, then click the "only apply to selected miners", and select your rig that will be connected to the Smart Plug. Now, add a trigger for this Awesome Miner rule. If your rig crashes in a way so that it doesn't respond to pings, then make the trigger to be a Ping (on timeout) function. In my case, I chose to make my trigger "activate" if the rig isn't responding to pings after 9 seconds. There are other triggers you could use, and you can even stack them for different conditions, either selecting the "Match all" (for an AND function), or the "Match at least on" option (for an OR function). Sounds complex? Nah, it's easy.

Finally, you need to set an Action in the Awesome Miner rule. In our case we are going to stack a bunch of functions to be run in sequence. The first action is to send an email to the IFTTT email address (trigger@applet.ifttt.com) with a #plug1off in the subject line. Then I put a Wait action for 10 seconds. Then put another email action to send an email to the IFTTT email address with a #plug1on in the subject line. Finally, I put 6 individual wait actions for 60 seconds each. It basically runs like this:

If no response from IP address for 9 seconds then
Send and email with #plug1off in the subject line
wait 10 seconds
send another email with #plug1on in the subject line
wait for 60 seconds
wait for 60 seconds
wait for 60 seconds
wait for 60 seconds
wait for 60 seconds
wait for 60 seconds

You need the waits in there between the off and on action to give your rig a chance to fully power down. You also need the waits in there after the turn on action so that your rig has a chance to boot up and start responding to pings again. I put six waits of 60 seconds each which is plenty of time for an SSD rig to boot up and start responding to pings... but it also means that the Awesome Miner rule won't run again for 6 minutes in case something is wrong.

Here's a quick shot of the Awesome Miner rule setup:

If you click the option in the Awesome Miner rule at the bottom to "Support manual activation" then you can run the rule actions at will from the main Awesome Miner mining rig list under the Actions dropdown. And if you have a license that allows a web page interface for Awesome Miner, then you can remotely trigger this rule at will while you are away. That's fine and all... and could be good for getting something unstuck.

The whole point of using Awesome Miner is to allow your rigs to keep mining, and it allows some pretty incredible automation. Couple Awesome Miner's already rich feature set for automation with Smart Plugs and IFTTT and you've got Puwaha's Poor Man's Networked PDU!

There's probably a lot to absorb here, so I'm more than willing to answer any questions or help you out.

Hello.

I want to share with you a simple program to automatically hard-reset your machines if they got stuck.

I'm using Raspberry Pi with 5V relay but you can use any other mini-computer as well (Beaglebone Black, Orange Pi & etc.). I will add better instructions with pictures soon.

Logic is: Ping machines every 33 minutes. If there is no response - Hard-reset.

Just download the binary file and edit the config.json

Soon I will add web interface for statistics

Additional information and basic instructions are available on github

Guys, the idea is to bring all 1080ti owners that been doing lot of test on miners & pools.
every month the profit drop because of the difficulty, so let's see how much profit you can get & shear to discuss...

POOLS
NiceHash
External Payout 3%

*super easy to use
*I quit because of high fee and low profit

1 1080ti profit: TBD

Minig Pool Hub
1.1% total fee = 0.9% pool fee + 0.2% exchange

I like it because...
*low fee
*you can mine altcoin and exchange to any coin
*control the daily profit
*many algos for autoswitch or mine the most profitable coin in a algo

1 1080ti profit: TBD

ZergPool
0% fee

in doubts of the quality...
*steal 30% of hash rate
*many people have problems with this pool
*seems to be the brother of Zpool and have a bad reputation
*mining profit spikes too high that it's unreal (this is because of the value of shit coin)
*Dev support not replying to technical questions. Afraid to reveal hidden secrets

the good thing is...
*you can mine lot of shit coins
*mines 2 or 3 coins at the same time in a algo
*0.004 payout on sunday (some people didn't get paid)

1 1080ti profit: TBD

Flypool (recommended by crairezx20)
1% fee

Pro
*Mine Zcash, the most profitable on equihash
*Part of Ethermine which they have a very good reputation
*1 of the lowest payout with 0.001 ZEC

Cons
*only Zcash. Sometimes other coins are more profitable.
*Lyra2Rev2 is the second porfitable algo and not available. So keep in mind what you want to mine

INTERFACE
Awesome Miner
the only cons are...
*need to pay for more features (reasonable in my point of view)
*Limited pools available for profit switching
*can't add mining software

Sniffdog
I need to test and might do it next week

OC/UC
For Nvidia is not difficult to do it with afterburner or GPU Tweak II. Lot of people fail to OC because of the power limit that is not enough, for this, need to use a power monitor.
Playing with OC/UC I could control the temperature and hash rat. Note: giving more clock to the limit, the hash rate drops
this is my results on equihash

BTG
GPU Clock 65 / Memory Clock 303
716~742 sol/s

Zcash
GPU Clock 65 / Memory Clock 303
730~740 sol/s

Zencash
GPU Clock 65 / Memory Clock 303
722~737 sol/s

*tested with a Platimax 1350w on a rig with 4 1080ti

PS: the objective is to get BTC at the end for cashout. I can update the status if everybody share

I don't think there can be full-fledged advice on this topic. Most learn from their mistakes and only then start to go into profit. You just need to analyze the market more.

It's all about learning by doing and avoiding doing same mistake several times.
Knowing how indicators work, what candle and chart patterns are etc. is just theory.
But getting a feeling for the market and how certain coin charts behave is something you will only learn when you trade again and again.
The more and longer you do it, the more your experience will grow over time.
But it's also about patience and the will to go through tough times when you feel you're not progressing. Hang on and do not give up!
And please don't fall for all that shit sales pitch and signal group out there. All you need is for free on the internet! Youtube is your book where even don't have to read! Just watch. Then join active trading communities and share opinions and informations with others who are in the same boat with you. Then you're on the right path!

Hello,

I'm hoping to get 75 S9's in my garage. I'm planning all of this out and am trying to figure out how many amps I need to support that. Is it right I'd need almost 500 amps to my garage to support all 75 S9s?

I'm very confused on this math because I've seen many posts that say 400 amps support up to 100 S9s but that doesn't jive with what I'm calculating what I'd need.

Thank you!

There are a LOT of post explaining this, but one more time, in round numbers:

Frequency * power consumption / joules per GH = chip power consumption
chip power consumption / power supply efficiency = 12V power drain, shy a bit for fans, the controller, etc.
wattage / voltage = amps (remember Ohm's law???)
breakers should never be continuously loaded for more than 80% of their rated capacity
wire should always be rated at the breaker rating (or larger, but nobody commonly does that)

so:

13500 MH* 0.098 J/MH = 1323 watts (just like the Bitmain page says)
1323 watts / 0.93 efficiency = 1422 watts, call it 1450 with fans an controller for this exercise
1450 watts / 220 volts = 6.6 amps
20 amp breaker allows you to use 12 gauge wire, which is easier than 10 gauge if you opt for 30 amp breakers
20 amps * 0.80 = 16 amps allowable per breaker
Therefore: You can put 2 miners on a 20 amp 220V breaker

(75) S9s would require (38) 20 amp 220V breakers.

A 200 amp breaker panel has a 200 amp master breaker at top. 80% rule applies to that too, so 160 amps total usable per panel.

160 amps / 6.6 amps (which is pushing it to the limit) = 24 miners per panel or (12) 20 amp circuits, but...

A typical 200 amp indoor main breaker panel has 30 spaces, 60 circuits, 15 spaces per side. Each 220V breaker requires 2 spaces, so you can only get (7) 220V breakers in per side, but that would overload the panel since 7 per side = 14 breakers = 28 miners = 185 amps which is greater than the limit.

You can find 20 space, 40 circuit 200 amp panels that work out better: 20 spaces = 10 breakers = 5 per side. 10 breakers = 20 miners = 132 amps which is comfortably below the 160 amp limit.

Using those 20 space panels would mean you would need (4) such panels. To power them, you would need 75 * 6.6 = 495 amps of continuous draw power spread between those panels.

That is excluding power for lights, fans, etc. (not to mention the rest of your house)

Then there is the minor problem of getting rid of 1450*75 = 108,750 watts of waste heat, but that is a different discussion.

Oh, and dealing with the noise.

It should be noted that the last word is "partially" a checksum... the way the seed is "broken up" is into 11bits chunks... 11 bits = 2048... hence 2048 words.

As per BIP39 (https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki#generating-the-mnemonic), you start with Entropy which is 128 to 256 bits... and divide that by 32 to get checksum length... in the case of the Ledger, they use 256 bits... so checksum length is only 8 bits... but the last word is 11 bits of info... so it's actually partially data/partially checksum.

This is why, even with just the last word missing there are still multiple "valid" combinations... as (for a 24 word mnemonic) the last word will have 3 bits at the beginning which are data... and generate up to 8 different values which will generate 8 different words.

In the UK house run 230v. the socket ring will start/end in the fuse box usually in a 32Amp breaker. (go check your fuse box; often the rings are labeled). So you can draw 32*230 = 7360W on the entire ring. The highest rated fuse you will find in an appliance plug (including your A3; and yes the Bitmain APW3++ is the easiest way to go). 13 *230 = 2990W, therefore the maximum total wattage you can have plugged into an individual socket is 2990W. I believe you need to not exceed 80% of maximum load (someone please correct if wrong) of this if you are running continuously (like a miner). 80% of 2990W is 2392W. So in theory each socket can draw a max of 2392W until you reach the total ring load of 5888 (80% of 7360W).

Typically a washer will be around 700W but may go higher for shorter periods of time. All appliances will have a sticker telling you the info.

The A3 is 1186W and a washer of 700W so these could both be on the same ring (probably best not to have them in the same socket), with quite a few other appliances.

Again, I am not an electrician so if anyone else here has and more informed information please chip in. If in doubt get it checked!!!! But one miner shouldn't cause you an issue. What country are you in?
