What is Bitcoin Mining? How Does it Actually Work? (2020

Need some troubleshooting help! Riser 008s and R3c

This project isn't for gpu mining but I know these risers are mainly used for this purpose so I thought I might get some good feedback here. My project is that I have an itx board with a single x16 pcie slot. It also has 3 m.2 pcie gen3 x4 slots. I have one free m.2 slot and wanted to convert that to x16 via riser. I wanted a 2nd low power silent gpu added to the rig. I went with the fanless msi 1030. It has a max draw of ~30w so I figured sata power would be safe. I purchased this and this to test with. Neither work!! So it must be something on my end?? The first part is fairly standard, the difference being I'm going to a m.2 slot where most of you are coming from x1 or x4. "In theory" this should just work! I'll start with the 2nd part since it's very simple: m.2 connector -> x16 socket + sata power. I hooked this up, seated the gpu and booted up. Nothing. Not even bios. I pulled the gpu and booted. Bios worked and booted up (running a 1080ti direct on the board). Installed the gpu back and nothing. I bought the 1030 used so I pulled the 1080ti and installed the 1030 direct to the mb. Works! So then I thought maybe the riser is bad or that sata power is insufficient seeing that most gpus would also have 6+8pin direct whereas mine has no external power. So I swapped risers out. This time the 008s with additional power connectors. Exact same thing. First I powered via pci only. Then sata+pci. And finally sata+pci+molex. In all situations the red led lit up. In all situations if I do not have the gpu plugged in it boots up fine. The strange thing is I never get into bios. No speaker or post lcd on this board so my troubleshooting is limited. And to note I test both gpu hdmi ports just to make sure one vs the other was set to primary. I got lazy and just looked at my mouse to light up to see if it booted. The mouse stayed dark, implying it never posted. Any help would be greatly appreciated! solved I have two m.2. ports which are pcie only. I have 1 port that is pcie/sata. the suggestion by u/sqrtlurface was to use the pcie/sata port and now the 1030 is being recognized in both linux and windows.

/r/Monero - Newcomers Please Read. Everything You Need To Know.

What is Monero (XMR)?
Monero is a secure, private, untraceable (crypto-)currency. It is open-source and freely available to all. Don't believe us? Click here.
Monero is a tool that people can actually use. It makes receiving payments hassle-free, since merchants and individuals no longer need to fear the source of funds they are accepting. With transparent systems like Bitcoin, Ethereum, Verge, or Dash, these people need to hope (or spend substantial resources verifying) the sender did not use the funds illicitly. Furthermore, merchants do not want all their vendors known, and individually do not want everyone to know how much they are spending. If I spend more than I should at Newegg (store), that's my own business.
Monero is different because every transaction is always private. There is no way for pools and exchanges to opt out of sending private transactions. Thus, Monero's anonymity set far exceeds any other coin's anonymity set. Over 86,000 transactions in the past month of August, 2017 hid the sender and receiver, and about 99.95% of them also hid the amount (will increase to 100% of all new transactions in September)! There is no suspicion in using a private transaction, since all transactions are private. A single transaction does not stick out.*
This privacy is afforded with the best technology. I implore you to take a few minutes to learn about the four main technologies that Monero uses to provide privacy:
There are several other things that make Monero great! It has a smooth tail emission, dynamic blocks and fees, and an accessible Proof of Work (mining) algorithm.
*You can optionally choose a very large, unusual ringsize to make the transaction stick out. This is not recommended, and normal users who leave the ringsize at the default setting will not experience any issues. Also, it's possible for a user to manually add identifying information to the tx_extra field, which is something that a user must seriously go out of their way to do.
Now you know Monero (XMR) has the best technology. What else makes Monero (XMR) different than other cryptocurrencies?
P.S. Want a quick-start, simple your-grandma-could-do-it guide? Here's a great one!
Am I a bad person to consider using this?
No, Monero is freedom money. You can do whatever you want with it, whenever you want, where ever you want. We make it clear that you should own your wealth 100%. What you do with it, is none of our concern.
Where does the word Monero come from?
The word Monero comes from the language Esperanto. Monero means coin oand currency. The plural way of saying Monero in Esperanto and in our cryptocurrency is Moneroj.
How do I store Monero?
Monero Core
Monero Core GUI (If you don't know how to use it, click here for instructions and tutorial)
Monero Web-Wallet
Offline Wallet Generator
Is there a lightweight wallet for Monero?
Not yet, but you can use the official GUI with a remote node.
Are there any other ways to store Monero (XMR)?
Yes, there are many mobile wallets out there that allow you to store Monero (XMR). We do not recommend them, because they are not official releases of Monero. If you do decide to use other wallets, please make sure to do your research first before storing any Moneroj in the wallet. Anything used for Monero outside of official releases, will be used at your own risk. Some may be used for scamming purposes. If you still decide to take the risk; do not use them for large amounts. Also keep in mind that there is a high chance that Monero support will not be able to help you if you bump into any problems from applications outside of official releases. Why should you not use non-official wallets? Well would you buy a house and give your only key you have to the buildemanagement and wait for him/her to open the door to the house you supposedly own? No. Same goes with cryptocurrencies. You should always have possession of your private keys, and your Moneroj. Most non-official releases own your private keys, therefore you do not own the Moneroj.

I hate my Fucking Mining Rig - Short Story of my mining adventure (Don't really hate it)

Wanted to write a short write up on my journey of Crypto mining for some of the newer people and people who want to get into it. Not trying to discourage anyone from starting, but want to show the progression of a newbie.
So I am a good with computers and learned of Bitcoin when it was about $7 a coin. Laughed at the idea of some computer doing some math and getting some BS currency. Million dollar mistake on my part, but hindsight is always 20/20.
Anyways, Learned about ethereum in May. Bought some at around $180 and bought all the way up to $330. Now to the mining rig. Ran all of the calculations and with a 180 hashrate and 900 watts I was gonna get 6-7 Eth per month. Shit was gonna be profitable in under 3 months. I was gonna be a fucking crypto allstar and be rich as fuck!
Bought all of my parts literally the day before they were nonexistent. Literally bought the last RX480's from Amazon. Here is a list of my parts.
Asrock board Pentium dual core processor 4 Gb of ram 128 gb SSD 1200 watt Rosewill PSU 6 Sata to Molex PCI Risers (Junk) 6 RX480's - 2 Asus Strix, 4 Gigabyte Total cost - Roughly $2,500 (Pennies compared to my future ROI)
Please keep in mind that I am not posting every single miner issue that I ran into such as fucking with Wattman for a few weeks before learning about Trixx and Afterburner.
I've built computers before, so that part wasn't hard. Set everything up and get windows 10 running.
Problem 1 - Computer doesn't see all of the cards. Had to run the drivers a few times and tweak some shit, but got all 6 cards seen.
Miner hurdle (See what I did there) but off to the races. Let's get this bitch running so I can begin planning my retirement.
Get Claymore running, Got Trixx to overclock. Ran my cards at -96, 1200, 2200 fans at 85% (Cause I'm cool like that.) Major stability issues from the start. 1 card (Asus) would crash all the time. Didn't know about the watch dog feature in claymore that would restart my rig when a card crashed. Great feature but my computer would go into this state of having power, but not loading the operating system. Even if it did restart, most of the time claymore would get stuck right before setting the dag's and would just lock up. (Claymore program is awesome by the way, this was my rigs fault)
Could not get this fucking Asus card to stop crashing, even on stock settings. Sent the bitch back RMA style. Asus said something was wrong and sent me a new one.
Awesome, lets get this bitch running. I need to start looking at sick houses in Costa Rica to move to once I am rich as Fuck!
New card makes things better for a few days. Not 100% stable but better. Go to vegas for a driving thing (Race cars - Future rich guy stuff) and this mechanical demon starts crashing every few hours. Luckily I had Google remote desktop installed so I could log on and restart it or change settings in Trixx. Had to have my GF unplug it and plug it in a few times.
Get back home, fuck with this thing but still random crashes on random cards. Decide it is the PCI risers. Contact seller who will send me some more for free. Slow boat from china took two weeks to get them. They arrive but still some of them are bad. Can't seem to piece together 6 good ones.
Did some research online (Ethereum Forum and Reddit) and decided to get some new style of risers V007 6 Pin to Sata ($70) and they take a month to get here. Plug them all in and they seem to be working much better. Decent stability, But I ain't got time for fucking stock bios. Let's ramp these bitches up and get 32 MHs per card at 600 watts from the wall!
Actually flashing the bios was pretty easy. Thank you 6 pound 9 ounce baby jesus! Long story short had some major stability issues and bounced around with some different timing straps before finding the right ones. (Uber 3.1 for Samsung memory)
So now that we've got some good hash speeds and decent stability let's ramp this private ATM up a little bit by dual mining some Decred. Get dual mining up and running. go to sleep. Wake up the next morning expecting to see myself on the top 100 forbes list. look at my mining rig stats on my phone and see that it died roughly and hour after I went to sleep. Walked toward my rig on the red carpet I had just installed and saw that it was off. Flicked on the light to check it out. No light, WTF? Well I'll be god damned, no power in this whole fucking room. Checked my breakers and sure enough this metal motherfucker tripped my breaker.
No worries though. I'm smart as fuck. I'll just undervolt the shit out of it to get the power down. No way in hell I am just mining ether. I'm going balls to the wall!
As you can expect I had many days of stability issues and tripped breakers. But fuck it, I have homeowners insurance. Burning it to the ground will be covered. (Didn't happen)
My surge protector must be maxed out. Let's buy a bigger one ($25). Same issues.
Fuck Decred, I'll mine SIA, less power. Damn I'm smart.
Rig is more stable with Sia and no tripped breakers. Family medical emergency, have to fly north for a few days. But my rig has been fairly stable and I've got remote desktop if anything goes wrong.
Arrive at airport, check mining stats, rig is down. No worries remote desktop. FUCK, not responsive, no way to remote into the rig and no way to remotely power it off and on.
Lost 4 days of mining. But no worries the difficulty is only, Holy shit that's high! But the price of Ether will make up for it. Ether crashed to the $200's. Oh well, maybe a 10 room house in Costa instead of a 12. No sweat.
Get back to my house and this whore of a machine is just sitting there in a computer coma. It's on but it's not. LED lights glaring at me like "Fuck you human, I ain't doing your stupid math problems!" Fuck you machine, I'm your master. You will do my math problems and you will fucking like it.
My AMD Drivers seem to disappear and the computer goes into a coma like state. Someone on Reddit suggested using the 16.9.2 drivers. Installed and they worked better.
Still random crashing. This shitty PSU must be maxed out. Fuck you PSU, I'm getting you a little brother (EVGA 750 gold $120.)
What do you mean you have to jerry rig a second PSU so it starts without being connected to a motherboard? 2 more hours of my life wasted.
But finally some stability. On my way to being fucking rich. I start looking at people in bentley's and can only laugh. You dumb fuck, I'm gonna be way richer then you. Gonna get a Bugatti for each day of the week.
Damn this difficulty is a bitch. Fuck you Genesis Mining and your pallets of GPU's. You're killing me smalls!
But anyway, on my way to rolling around in my fuck you money!
Fuck you dag file 135, you're killing my future millions. Fuck you dag 138, you dropped me to 167 mhs.
Thank god AMD was there to save my ass with their dope ass blockchain drivers.
download, run DDU, Restart, install drivers, restart, run pixel patch, restart. Perfect, I'm in the money now! I can taste the caviar and champagne already.
Now my cards only run 4 Mhs each. WTF? Try a bunch of the other new drivers. Same shit. Roll back to 16.9.2 and they run fine, just at 167 instead of 180.
Someone on a forum said he had the same issue and did a fresh install of windows 10 and it worked.
So I'll just reformat my SSD (Windows wouldn't do a fresh install within the operating system. Fuck you Bill Gates! Gonna buy you once I get this thing running at 180.)
Format SSD, plug back in, throw in my gangster ass boot USB drive. Ramdisk error. Fuck you Bill Gates! Reformat SSD multiple times, lots of forum reading. Install windows from another computer through command prompt (I'm a coder now as well.) This shit has got to work, I did it in command prompt bitches!
Same fucking error. Now down to an 8 bedroom house in Costa and only 6 Bugattis.
Let's try unplugging my 6 cards and see if that works. Thank you 6 pound 9 ounce baby jesus. Windows installed.
New drivers work and I'm back at 180! Raking in the cash now.
With those speeds my Asus cards crashed. Had to dial down the hashrate to 177.5 for them to be stable. So now going to use some commands in claymore to run the Asus cards at lower speeds while letting my other cards mine harder.
I wrote this to let people know that mining isn't all Bugatti's and caviar. These machines are fickle little cunts that do what they want. No system is the same. So when you post on a forum, people will give you advice on what may work. But what works for them, may not work on your rig. In the end it's up to you to figure it out.
I have spent countless hours after work and on weekends working on this bitch. Hell I've probably spent a few hours just staring at it and thinking about all of the ways I could destroy it slowly.
While I love Etheruem and do value the knowledge gained, I would have made more money just buying Eth and holding.
The guys you see on youtube building sick rigs with crazy specs have been at it for a while. They have worked through the process and know how to solve all of the problems. You have not and will have to work them out on your own.
My whore of a rig will pay for itself soon. But I would suggest that if you want to start building a new mining rig. Check the difficulty chart and make sure you have tons of free time to fuck with it.
I'd post my wallet address for donations since I just saved you $2,600. But I am afraid hackers will steal my monies :)
Hope you enjoyed my mining life story from the past few months.

Edit - Had an Asus card die on me and replaced it with a 1070ti. Nvidia is so much easier!
My rosewill 1200 watt PSU melted the 8 pin port and cable. Had to drop $300 on Amazons last 1300 EVGA.
But my rig has well surpassed it's cost and is still mining away like a champ. Eth for life!

Romantic or not, who's someone who has truly changed your life for the better, or who you're just plain grateful to have around?

Wall of text incoming. May not be germane to the topic per se, but felt like writing it.
For me, it's my best friend who I originally met in sixth grade. I had been homeschooled up to that point and I was always a socially awkward kid with very fringe interests, and I got taken out of elementary in second grade because of bullying, so I was understandably reserved about starting middle school and reintegrating into the public school system. I still remember it, clear as day. It was my first day of sixth grade, and being myself I had shown up in full formal dress - button-down shirt, belt, tie, the works. (Don't ask.) After homeroom, I walked into my first class of the day, English, and sat where there didn't seem to be anyone else. Then he walks in, sits right next to me and starts a conversation, I think about video games. I mentioned some obscure game he didn't play (of course), but he played along and acted like he did and even BSed his way through a couple questions I ask him. We exchanged emails and before the end of the month we set up our first sleepover, and the rest just went. He was also an awkward kid who didn't have many friends - obviously not as bad as me, but it allowed us to establish a connection.
We had a ton in common from the get-go and it seems like we get more and more each day. He introduced me to Steam, convinced me to setup an account and talked my mom into allowing it, and got me into PC gaming; then I got into PC building and hardware, convinced his dad to let him build one and helped him build it, and then watched him build a second one completely independent of me about two years later. I taught him how to touch type and write well, and I'll still go back and incredulously read some of the stuff he would write one or two years back. He spurred me onto the idea of starting our own business when he was at my house one weekend, a business which has now grossed over $3k with us as pretty much the sole proprietors and employees. He got me into cryptocurrency back in early 2015 when Bitcoin was $300 and he had his own jerry rig of USB miners, a topic which I'm now very actively involved in and doing my science fair project on; we're also planning on divesting some of our business earnings into a legitimate mining venture. And so on, and so forth - anything he gets into, I get into, and vice versa ad infinitum. We have so many common interests and we know each other so well it's crazy.
Above all, he took me out of my shell. In the middle of eighth grade, he recalled that day we met in sixth, and said he noticed me sitting alone at the back of the class and decided he'd give me a chance. God fucking bless his soul, because I don't think there's been a single more pivotal point in my life. Talking, chilling, and doing stuff with him all the time gave me an actual practice base for social skills and convinced me that I was someone worth putting myself out there. I started sitting with the "cool kids" at lunch at one point, and now they all say I'm one of the best people they know and they're glad to talk and hang with me even though I don't necessarily align with their interests. I sent a Snap to everyone I felt grateful for this past Thanksgiving and nearly all of them had great positive stuff to say back. When I walked in the door for the first time at my day camp this summer, the whole room lit up, and everyone was glad to see me. It's fucking incredible how far I've actually come and I owe almost all of it to him and the chance he was willing to give me back then.
But most importantly, he's still the best friend I have, and I'm still the best friend he has. We still have more in common than any other two people I know, and likewise for how well we know each other. Every time I go over to his or he comes to mine I feel genuinely happy and glad to see him again, in a way that almost nothing else makes me feel. His mom died unexpectedly towards the end of eighth grade, and at the funeral I cried fucking uncontrollably because I truly do feel for him. We went on to different high schools, and we both have way more non-mutual friends now and do tons of things that aren't with each other, but our link is still the strongest of all. He lives on the nice side of town and I live in the ghetto, he's Jewish and I'm a Catholic-born agnostic, he doesn't give a shit about school and I have a 4.9 GPA, he's a die-hard Apple fanboy and I have an Android, and on and on - but none of that shit matters. We're friends, and we're great friends.
I felt compelled to write this because "Still the One" by Orleans came up in my playlist today and I noticed how many of the lyrics feel relevant to us, minus the romantic part. "Sometimes I never want to see you again...but I want you to know, after all these years, you're still the one I want whispering in my ear," "Changing, our love is going gold...even though we grow old, it grows new," etc. etc.
Thanks to anyone who read that. Who's someone like this in your life?

I've started working on modifying the Vive wireless adapter for better passive cooling.

First and foremost: I voided my warranty, this is not a how to, this is an attempt to see if anyone else is working on a similar solution and to get as much input from as many people as possible. Please chime in if you have any thoughts on the subject. I have the Pro version, which means the adapter is under more strain, it's constantly at the bandwidth limit in most games.

I have no background in engineering nor am I in any way qualified to do this, but I did mine bitcoin back in the day and learned a lot about heat accumulation and dissipation. My proudest achievement was running a 6 GPU rig on my balcony for a year consecutively in Finland with the ambient temperature of -30c to +40c. Almost nothing ever caught fire :) This experience leads me to think that it's a bad idea to draw more power trough the headset, from the same battery for a fan. Also I have long hair and am downright afraid of adding a fan to my head.

I have begun to cut off some, not all of the, "plastic strips" covering the openings in the adapter. I intend to remove about half of them, every other to be exact, removing all seems like it could weaken the "chassis" too much. If that is not sufficient then I'll open the entire thing out and try to figure out if there are spots where small aluminum heat sinks could be added without interfering with the reception. What material would be the least interfering with the reception whilst having the greatest possible thermal conductivity? The answer is probably not metal at all?
Here's where I began, I intend to go back and smooth the edges, possibly with a soldering iron: https://imgur.com/a/smMdT7n

I'll try to post updates in comments as the chopping progresses, hopefylly we see some input before entirely "gut the sucker" :)

Anyone considering adding a fan might want to cut off the "plastic strips" covering the openings in the adapter from beneath the spot you intend to add the fan to, especially if you intend to glue the fan on to the adapter. Actually I can guarantee this will improve the (unknown to me) efficiency of your fan mod by a double digit %.

[edit1]
I have removed roughly half of the strips and done some testing, not enough to say anything conclusive, but the adapter seems slightly cooler after and during intense use. I did play a full battery's worth of Skyrim without seeing a grey screen, this has happened before, but not that often. I discovered the back "plastic strip" has a clip that's holding the enclosure together. Had I known this I would of not cut it, looks like it missing wont be a problem tough. I have clearly created openings that will gather dust, so from here on I'll make a routine of blasting the adapter with air duster from time to time. It's obviously also more vulnerable to liquids now, but I don't see any sweat getting in from the top and sides where the modifications are.

Has anyone opened the adapter up, does a teardown guide exist?

[edit2]
It just occurred to me that anyone using a fan mod would achieve greater efficiency by running a split usb cable, so the fan does not draw power trough the headset. If my current tinkering proves inefficient I will probably go this way myself. Having the fan pull air trough the top of the headset, rather than pushing it in.

[edit3]
10 hours of gaming in and I haven't seen a grey/blue screen yet. Apart from one IRQ error, those usually bsod my whole computer. Unfortunately I seem to be stuck on that front because my mobo's bios dosen't seem to include any IRQ settings at all.

[edit4]
Haven't seen a grey screen since the modifications, but my holodeck is in a room that gets no heating, so the ambient temperature has been 5-10c less than usual. So I'm pretty sure I have no valid findings to report atm. I will, only, continue working on the adapter as the problems re-emerge. Doing anything now seems like fumbling in the dark.
[edit5] Been slightly warmer so yesterday when I fired up Moss and turned the graphics options all the way up I experienced the first grayscreen that lasted longer than a second and did not recover on it's own after beginning modifying the adapter. This was after ~20 minutes of playing. So I proceeded on with the chopping, I promise pictures soon but atm there is no light, I have now cut all the strips on all the sides, 6 out of the 18 strips on the top mid part remain and 1/3 on the horn's remain. Please note that I've concluded that cutting the strips on the horns does absolutely nothing heat wise, so knowing what I know now I'd leave them be.

I'm about to attempt to overheat the thing with Moss next and if I succeed, I'll start looking at usb fans.

[edit5]
Did not overheat this time around, regardless I'm looking at fans. Optimal sizes seem like 5cm or 7.5cm diameter. As explained earlier I'll go for a "split cable" or "passthrough" to avoid running any extra current trough the adapter. I'm pretty sure no ones reading this, but I'll keep updating it and will re-publish if I feel like I've gotten the issue sorted. Not covering the button seems harder than anticipated, I should move it... but I don't feel comfortable doing that. I guess I'll order a bunch of fans and see what works out once I have them in hand.
Note to self: the added usb cable/'s should run under, not over the adapter. So that we don't introduce copper wires to block or hinder the signal. This means the minimum cable length is ~13cm. Arctic cooling can move 15.1 CFM / 25.7 m³/h @ 0.08 Sone (@ 1,200 RPM) with a 8cm fan. Settling for less than half of this would be madness. USB to 2 x 3/4-Pin PWM 5V USB Sleeved Dual Fan Power Adapter Cable exists, were not settling for less :) I orderedhttps://www.amazon.com/gp/product/B077PXJRTT/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 mainly because they did not attempt to screw me over with shipping costing more than the 800% markup product.
and https://www.arctic.ac/eu_en/f8-silent.html because they make the best products in the field. at 5v this runs at 400 rpm, completely silent and still shifting 5 CFM or 8.5 m³/h. If this proves inefficient I can try running it with a separate 9V battery, no speed is indicated for 9V, but that'd reach 700-800 RPM and increase the airflow at the same rate.
Still looking for usb male to male type a splitter (all male) these don't seem to exist : /
[edit6]
Gave a try using a soldering iron to smooth the openings and cut edges, not a huge success, but gets the job done.

Did some log digging, things are bad:
The latest log is three days old, it shows the adapter consistently hitting 80c and during one session, I suspect it's Moss, but can't be sure, it gets really bad:

87c that's not a safe amount of heat to attach to the top of your head. That's also a temperature that would kill a GPU if constantly reached.
And here's a snippet for the inevitable nay-sayer claiming I've made it worse it's from a day before the original post and before I made any modifications to the adapter:

Fan arrived, I got the size right, but can't proceed to test before the cable arrives. I did think of a lazy but promising way of testing ways to mount the fan: I'mma just ziptie it to the horns and experiment at different angles with wedges of cardboard to hold it. The fan weighs 71g and the plastic strips that I've removed total about 6g. I'm pretty sure I can shave off up to 10g from the fans plastic components once I decide on a mounting style/method. There'd probably be an another 2g to shave off by shortening the power cable, but in my case I'll need a friend to do it for me and I was thinking of shortening the power adapter cable to the bare minimum too so might as well stack the jobs. I'm also scrounging for a net of some sort to keep my hair out of the fan, that'll obstruct the airflow like a mf especially as I'm adding one to both sides... but I'm hopeful that the fan is overkill enough to still do the job and keep me cooler during Beat Sabre.

Bitcoin farming discussion

So I was watching a slushpuppy Tarkov stream and chat got talking about bitcoin farming with quite a few people seeming to want it in. Gave me an idea, I figure I'll throw out there up or downvotes I just want some opinions on how you think it should be implemented or even if we should be able to farm them (Obviously this is a lower priority than optimization and netcode fixes) . An interesting way to implement bitcoin farming in my opinion would be you have to set it up on an in-raid computer and it has a 85% chance of spawning a bitcoin next raid if you go to the same computer, but anyone else can also have a crack at the PC if they get there first or kill you for it. Computer can be setup with or without a lock, pricier with one cheaper without, the difference being either one requires a codebreaker device (Costly USB) or some extra time to crack Obviously this would give you a virtual bitcoin and I figure a fair way of doing it would be to trade 2 virtual for 1 physical . No idea if it would work and it would possibly flood the market with bitcoins but I like the little interesting ideas . Probably have to have the mining rig it as a T4 trader item and really costly 500k+ roubles, have it be externally visible either via a monitor being running or something more subtle like a different usb in the computer Keen to hear some thoughts or alternate suggestions . EDIT: Did not know computers in the hideout was gonna be a thing my bad

[Discussion] My own personal guide to used hardware alternatives.

Hi there. My name is Jeff. I've been building systems for the better part of 15 years and try my best to contribute here actively. After being involved in this little community for a few years now, I'm noticing a serious lack of discussion about buying used components, and I feel like it's time to shed a little light on the subject for those looking to build on a (seriously) tight budget.
As Linus said in his scrapyard wars video, buying new on $300 isn't practical, and if you posed the challenge to him on a random day, buying used is almost certainly the path he'd choose. As someone who's been "scrapyarding" as a hobby for the better part of 10 years, I figured I'd take some time to share some of what I've learned for the modern audience.
Let's begin with a simple rundown of modern "budget" choices, and I'll tell you what I'd do instead.
CPU
The G3258 and Athlon 860k are the sub-$100 CPUs of choice, and both work just fine. I have built with both in the past, and each carries their own set of advantages.
Used Alternatives: You can go in a couple of directions here; if you happen to have an LGA 1366 motherboard lying around, you can get an i7 920 or better for under $50, and they still hold up reasonably well. Being that LGA 1366 boards are not typically cheap when purchased used, my favourite option is the Phenom II x4 Black Edition series, each of which compare favourably to modern budget options, and will even overclock on some incredibly dated, dirt cheap AM2+ boards. In my experience, eBay prices on these get a little too high for my taste, but I've been able to nab several on Kijiji locally in Toronto for under $50 as well.
GPU
The R7 260x and GTX 750 ti are often cited as budget options for most builders, with the latter serving a very specific role in systems where power draw might be a concern. While there exists no option that can complete with the low consumption of the 750 ti (or even the single 6-pin connector goodness of the 260x), its performance can easily be matched (and exceeded) for less money.
Used Alternatives: The bitcoin mining craze from a few years back led to the Radeon 7950 and 7970 being blacklisted on the used market, and I think the fears about burned-out cards are a little overblown. Here in Toronto, you can easily grab a 7950 for the price of a 260x, but I don't pay anywhere near that for my builds. At most, a Windforce will cost me $125, as where I recently picked up some non-boost edition PowerColor versions for a mere $83 each (bought 3 for $250).
EDIT: Forgot to mention something important - avoid the reference 7950 and 7970. They were employed to a far greater degree in mining rigs because of their rear-only exhaust, and if you see a bunch of them from the same seller listed at once, they're likely old mining cards. Only pick them up if they're incredibly cheap.
Want to go even cheaper? The Radeon 6950 (with the shader unlock, preferably) or even the 6970 will rival the performance of the 260x, and shouldn't cost Canadians more than $50-$60. I personally have 2 in my possession right now, and have gone through at least a dozen in the last 6 months.
In general, one should always avoid Nvidia when buying used, because they are far too popular and overvalued for their performance as they age. I still see GTX 660s selling for $150, which is absolutely absurd.
Motherboards
Motherboards on the used market are weird, and this can largely be attributed to the fact that they're hard to transport and don't handle well over time. As such, people don't really sell boards on their own that often, and you'll likely have more luck finding a combo of some kind (or even a ready-to-go tin-can with no graphics card) for less per part than you will finding a given board on its own.
Used Alternatives: The boards I'd recommend depend entirely on the CPU you've chosen. Being that I'm a fan of the Phenom II x4 series, AM2+ boards are going to be dirt cheap, but DDR2 RAM is actually fucking expensive, so you'd likely be better off going with AM3. I've even seen some used AM3+ boards (The 970 ASRock Extreme3, in particular) for as low as $40, so it wouldn't hurt to look.
On the Intel side, you're actually at a significant disadvantage. Much like Nvidia cards, Intel boards (and CPUs) actually retain their value and don't often come cheap. For me, LGA 1156 is the price/performance sweet spot, granted I can find an i7 8XX to go with it. Even still, they're going to run you a fair bit more than an AMD board, and likely aren't worth it by comparison.
RAM
Ram is ram. DDR2 is pricy as fuck due to an obvious market shortage of the stuff, so the AM2+ board option might not be best by comparison. DDR3 ram, however, is ubiquitous, and I always die a little inside when people building on a "budget" choose to buy new at all. If I'm being honest, I can get DDR3 ram from e-waste recycling companies for as low as $10 per 4GB stick, at 1333MHz, and not once have I ever had a bad stick of the stuff. Even for people going the route of the G3258 (which only supports 1333MHz), this is the clear winner.
Is value RAM ugly as sin? Sure it is. It is just as good as that fancy Ripjaws shit you've got in your current build? You betcha.
Storage
Hard Drives are actually a tricky game, as they are the single most volatile component in any budget build, easily succumbing to wear and tear from age and daily use. As such (and some might find this hard to believe) I actively avoid HDDs when building value systems for people and opt for cheap SSDs instead. As always, check the date on a drive if you're really insistent on buying one, and considering how cheap a WD blue is new, don't pull the trigger on one unless it's for less than $30/TB.
SSDs are obviously (akin to RAM) highly resilient and are nearly guaranteed to work when purchased used. The average SSD pulled from an old laptop or an office off-lease desktop, will have no more than 100GB of writes on it, which leaves 99% of its life for you to exploit. While there exists no specific recommendation for which brand to buy, just be sure you're getting a relatively good drive with SATA III capability. 120/128GB variants of these sorts should cost you no more than $50 in my native Canada, and I've even gotten lucky on some larger sizes too. Recently I picked up 4 256GB Samsung 840 Pros for $75 each (I came), just days after I bought a Crucial MX100 of the same size for $85.
Monitors
Monitors are fun to buy, because the recent shifts in display technology have rendered a lot of recent-but-obsolete models nearly valueless. For example, remember when 16:10 was a thing? I actually still like 1680x1050 monitors, but the rest of the world seems to disagree, so I've been able to pick up 23" variants for as little as $40. Being that the slightly lower resolution actually eases the strain on your VRAM a bit, it's a nice fit for a lot of budget cards that might not have a full 2GB available, like some variants of the 6950. 1600x900 monitors are often just as cheap and come with the same inherent benefit of being obsolete despite being almost as good as its bigger 1080p cousin.
Keyboards and Mice
If you're on a budget, we can't even have this discussion. As much as I like mechanical keyboards and high-precision gaming mice, people building used $300 systems aren't going to allot any of their budget buying them. That said, wired USB keyboards and mice are virtually free (search your local goodwill or value village for some), and if you have to pay money, buy a wireless combo for $20 new from some little shit store in a suburb somewhere.
Cases
Cases on their own sell for about half of their original retail price, give or take based on the condition. I normally just get them as a part of a tin-can bundle and make use of them if they aren't too dirty, but when building for someone else, I'd often just prefer to buy a new budget case in the $40 range.
PSUs
I saved this topic for last, because it's by far the most difficult category to master. First off, you really need to do your research and understand how PSUs work before delving into these guys, as the cost associated is almost entirely dependent on how resilient the underlying platform has been proven to be. Generally speaking, reading reviews on JonnyGuru and HardOCP is a great start, but none of them account for units that are several years old.
As a general rule of thumb, I use the EVGA 500W W1 as a reference point, and build my value tree around that. In other words, if a new EVGA 500W (a passable, proven budget unit) is cheaper than a used 500W variant of a better brand, why would I bother buying used? Sure, that 520W Seasonic S12II puts the EVGA to shame in terms of voltage regulation and ripple suppression, but can I really make the same claims of a unit that's 5 years into its life? Wouldn't I just be safer buying new? These are all factors you have to consider.
For me, the threshold lies around 50% in terms of cost savings vs. risk. In other words, if you can find a used quality unit for less than half the price of the cheapest quality unit available at a given time, buy it.
Anyhow I think that covers everything. And as a closing note, remember to be safe. Meet potential sellers (and buyers) in public, well-lit places, and try your best to avoid entering someone's home without some protections in place. Also, the more info you get about the person (address, phone number, etc) the less likely it is that a person will be trying to scam you. People who purposely conceal their identity do so for a reason.
Also, feel free to ask me anything about my own experiences buying and selling used. I've been doing it as a hobby for a long, long time and have sold many value builds to people who can't otherwise afford PCs. I'm happy to impart any wisdom I might've gained over the years.
Edit: CPU Coolers! Forgot those. Air coolers are a safe bet. They're slabs of copper and aluminum with fans strapped to them. Buy with confidence, and seek one out for $10-$15 if you plan to overclock. AIO water cooling is not so safe. Those things are typically only good for 2-3 years, and you have no idea how much longer a pump has before it gives. Budget builders likely aren't water-cooling anyhow, right?
Edit 2: Just to be clear, when I said I'd been doing this for a long time, I should clarify that a) I once owned a game store and sold systems out of there and b) I currently resell systems out of my house to raise money for charity builds. I really don't want people to get the impression I'm trying to sell anything.

New to mining, just discovered this Reddit. Rig ok?

TL;DR: look at my component list, is it ok? Or did I butcher it?
So after a few years of trading through exchanges (coinbase) and making a bit of cash from latest Bitcoin surge (not much, like others I sold thinking it would tank again, but hey, it's cash I didn't have before). I decided to make jump to mining. Never really use Reddit. So never knew there were communities on here for it.
Read reviews, guides, and forums elsewhere, and came up with / bought hardware for a rig. Plan on having it up and running before New year. Just wanted to check with some experts if I did ok, or if I made some bad choices. Open to suggestions and advice. Thanks in advance!
CPU : Intel CPU BX80662G3900 Celeron G390
MoBo: Biostar Motherboard TB250-BTC 1151
Risers (6 pack to have spares and room to expand) : Mailiya 6-Pack PCIe Dual Chip PCI-E 16x to 1x Powered Riser Adapter Card w/ 60cm USB 3.0
RAM (from what I understand 4gb will be plenty, I'm going to try my hand at Linux, but if that doesn't work out I have a win7 license I can use): Ballistix Sport LT 4GB Single DDR4 2666
PSU: EVGA SuperNOVA 1200 P2 80+ PLATINUM
I also already have some other equipment I plan on utilizing, a couple push buttons for power, a power usage monitor I have had for bit, but will work for this purpose. I also have an unused 120gb SSD that should work just fine, And I managed to snag an open air frame that someone must have given to a pawn shop, I found it there and recognized what it was, even though they had it labeled as a "server rack" technically true I guess) it came complete NiB for 100$ and retails for 160$ on Amazon, I was going to use an old tower I had laying around, but figured this was worth investment, it's a: Veddha 6 GPU Minercase V3C Aluminum
Finally, the bread and butter, 3 identical GPUs, brand new (I had an option for used, but got these brand new from a few different sources): ZOTAC GeForce GTX 1060 AMP Edition, ZT-P10600B-10M, 6GB GDDR5
All in all, including things I've bought previously and are still serviceable, this set me back about $1600
The goal was to have a rig I can not only expand, but one I will be able to swap out cards into / out of to upgrade without changing much else. Like any other miner I dont expect to strike it rich, but averaging a few hundred a month after power costs would be nice. I did some research and am thinking I can get my RoI in about 6 months. Before system is up and running I plan on researching more about pools (the guide here is great!) And picking some coins to go after other than Eth. I'd appreciate any other tips. Thanks for sticking around all!
So will it work? Or did I butcher it?

5 AntMiner S1's for my home mining rig?

Sometime mid next week (Jan 19-21) I should have ~$5,000-6,000 in PayPal. I am looking to buy 5 S1's direct from BitMain.
I've got a few questions/concerns however.
The biggest concern right now is being able to buy $5,000 of bitcoin, using PayPal. I'm 16, so withdrawing all that money to my student checking account is a no-go. My mom also doesn't want to give PayPal her tax ID, and credit card so she has unlimited withdrawing capabilities. I plan on asking around the Chicago Bitcoin Meetup if anyone there would be able to sell me that much Bitcoin, and for PayPal or something along those lines.
After I get the bitcoins, and the S1's delivered, any advice on keeping them cool, and clean? They'll probably go in my basement, and I'm thinking about some kind of horizontal rack, and cooling system. I'd like to overclock them to 208 gh/s. One of my friends has built a LN2 creator before, and was talking to me about possibly doing this for all my BTC miners, so we could further overclock them, increasing profitability.
I'd expect some kind of decent ROI with this setup, and yes current profiribility calculators will probably tell you I won't make much, but I'm gonna go out on a limb and assume Bitcoins will be at, or over $1,000 a pop by SeptembeOctober of 2014.
I also plan on using Coinwarz and mine the most profitable coin each day, and sell via cryptsy. I'll also just save some bitcoins for the future.
What kind of PSU's should I get for 5 of these bad-boys? Would 2 1050w PSU's and then another 700w one be alright?
My friend, who bought an Avalon Asic Batch 2 last year for ~$1,500 made a great ROI, and he is doing the same exact thing I am with this project. Except that he might end up with 10 S1's, while I'll have 5 of them.
If anyone has any advice for me, I'd love to hear it. I've been following Bitcoin very heavily sense I first herd about it in 2008 (It was only $2 a pop when I just went on #otc) but this will be my very first mining rig of my own. I've mined of my GPU/CPU using various coins, along with my usb asic, but this will be a large project/rig.

Two things: 1. Stop spreading FUD about ASICs and 2. Are too many exchanges a bad thing?

Hello shibes, I hope everyone is having a blessed day! It's sunny down here in NOLA and life is good.
I just wanted to stop everybody before we get 1000 posts about ASICs. ASICs have had a long and rocky history whereby the consumer has been royally screwed many times, and the ASIC developer has taken their bitcoins and laughed all the way to the bank (unless they were using MtGox to store their bitcoins).
Anyhow, any ASICs are projected to come out in Q2 or Q3 of 2014, a very optimistic and unrealistic date. To improve ASICs from their current 300kh/s per rig to 100mh/s per rig by then, in my opinion is laughable and expensive. Rewards will be much smaller by then at any rate, and that's if they come out. A big big IF. When they eventually come out, they will provide maturity and power savings to the network.
Anybody who is currently buying graphics cards can instead invest the same amount of money into a USB ASIC which consumes less power and provides higher hashrate. Anybody who hasn't invested currently in graphics cards can hardly mine, and that position will not change. ASICs are coming either way, and the fact that we are recognized and targeted by them is a good thing, not a bad thing. It shows we are a mature network. Yes we can make algorithm changes and keep distancing ourselves from mainstream financial systems, but we want to move forward, and this is what progress takes. We will still most have an early adopter advantage, so I'm not complaining at all.
Enough on ASICs. Que sera sera, and our community is too big to be killed by ASICs, so they will change things, but change can be good.
Second point: at this stage in Dogecoin, I think too many exchanges are a bad thing. Maybe I'm jumping the gun because they both launched, but prelude and coinmkt have very low volumes, and frankly at this stage I don't think our market cap can support 30 exchanges. I don't know 100% what the solution is, but I'd like to hear some ideas about that. For now, I just want 1 good exchange for the US and canada, 1 for EU, and 1 for China. Anything above that just dilutes trading volume.
Feel free to disagree with me, I'm just one shibe.

State of the Bitcoin community.

This may be a long post but I wanted to get a few things off my chest. Some of you may not like what I'm saying but if that's the case at least take the time to discuss it rather than downvoting me. I think that's what communities on Reddit lack - discussion is how we progress and sometimes it feels like all Reddit does is downvote instead of actually talking up.
Firstly - Bitcoin in the media.
It's no big news that Bitcoin was synonymous with Silk Road and the Deep Web for a while. You couldn't have one without the other. This lead to a lot of negative press for Bitcoin itself. I think it was handled quiet well, we showed the majority of people that Bitcoin was useable in a mainstream setting but I don't think we did enough. How often do we see the good features of Bitcoins like:
How often do we see these features? I recently saw a sign in my local shop saying they couldn't accept credit card payments due to high fees. Imagine if they knew about Bitcoin, as long as they have a computer or even access to one they could attract a wider audience.
I think we can do a lot more to give out a clearer message about Bitcoin. I think a lot of the fear comes from the fact that people don't understand it. If we spend more time educating then we can get a more positive image out there.
Secondly - Miners, their profitability and other issues.
