1  Alternate cryptocurrencies / Mining (Altcoins) / Chinese mining motherboards suck! on: April 15, 2019, 03:25:49 AM
A word or caution, even the Lexus of these turds are terrible. There is always an issue, they're finicky as hell, the bios are old and outdated. Stay away from the pieces of shit, just buy a reputable motherboard maker, a cheap cpu and a server case if that was your plan. Use good risers and forget all about that terrible Chinese shit.

Sincerely a mad motherfucker who's had enough of this bullshit and is buying a new server case and listing the Chinese shit tonight.
2  Economy / Services / Escrow for anything via discord by Dream (fpga channel mod) on: March 03, 2019, 09:56:33 PM
I just wanted to let everyone know that Dream the dogs channel mod has a discord server with low low fees.

His channel is here: https://discord.gg/MezcCxb

His fees are as follows

$0-$100- free escrow
$101-1000- $2
$1001-$5000 $5
$5000+ $10

This is all paid through discord rep (not 100% if he accepts crypto I am sure he will though)

He has a Bitcointalk account which is new : DreamBlob

He's already done 13+ btc worth of transactions and can verify it.

He's a great guy and if you're doing an OTC trade on discord I definitely recommend stop what you're doing and use his escrow.

He will escrow anything legal.
3  Alternate cryptocurrencies / Mining (Altcoins) / Octominer Server style case Review on: October 15, 2018, 03:22:37 AM
This is a review of the full server style octominer case, if you do not know who octominer is they are a company out of china with an international team that produces 8 slot riserless motherboards for GPU mining. More informatio can be found at Octominer.com

So lets start this out, the hardware I have been using is an Octominer B8plus Motherboard which has 8 PCIE x16 slots an integrated Intel  3855U, I used 4gb of Laptop style so-dimm DDR4L and a 32gb M2 ssd (although I actually ended up running off flashdrives for ease of switching OS)

I had this set up with four different 2.5 slot AMD gpu, two 480 and two 580, this was originally in an open air rig from Spotswood, that case has more information here: http://spotswoodcomputercases.com/wp/?page_id=9194

This setup is quite a handful and a mess of wires for the home miner as seen here:

This open air case also happens to have a bit of an odd psu mounting system that leaves a bit more to be desired, especially when using an expensive psu:

As you can see here when the board is not fully populated there is quite a large space between these cards, this is the only time I would actually really recommend not adding any extra cooling.

The package came via DHL in about 5 days from China (I want to say Shenzhen but I honestly can't remember) I had no issues with postage with this being delivered in the United States.

The box it came in really gave an honest feeling for how big this case really was going to be, but to my surprise it was quite light.



The case itself comes with three high powered fans preinstalled and makes the extremely long motherboard feel like a dwarf when first placed within.
This does give plenty of room to get everything installed correctly and set up, which was a great thing to me. You can also see the attached digital fan controllers back side from this photo, Octominer had sent me this and an analog controller as well.
I found my results with the included digital controller to be MUCH better as you can see what each fan is spinning at (RPM) and the temp in that area.

This also allows you to control each fan individually as compared to the analog single fan controller seen here:


The case itself fits everything very neatly on the inside and is made quite durably,


You can also see that compared to the open air the atx power supply fits quite well, this also comes with a bracket for fitting server style power supplies.


The front ethernet port connects to the ethernet port on the back, this comes through a small window beneath the power supply, i do wish this was handled some other way as this gives it an easy way to break a piece of the motherboard if laid down incorrectly.


My case also came with a custom engraved usb flash drive, this can be used for loading an OS if needed, I had already prepared an OS on a flash drive so I did not use it but it is quite the nice touch.



When it came to testing the open air system I had averaged a temp of 76c on all four gpu when mining Eth using the simplemining OS. This was a similar temp on a few different algorithms.

When placing the same setup in the Octominer case I was able to get the same temp with the fans set to 1200 rpm, when turning things up to 2200 rpm I was able to see temps drop around 1-2c, when cranking the fans up to their max (~4000RPM) I was able to see a temp drop of 3c on all cards while keeping all settings the same. It really seems to me that if you are going to be populating an entire 8 card board you will need to have these fans turned up to the highest speed to keep them cool and I believe they would stay cooler than an open air frame even with some fans due to an air tunnel effect. (static press blah blah blah) I also think that this case is a remarkably well made product and a beauty as well. My thought process for a case like this is that it will always have a use, GPU mining will always be relevant is one form or another and the main in tearing down and rebuilding an ugly, space consuming open air case just is a slow down. The ability to be able to only need to swap GPUs and keep the wife happy easily makes the decision for me. The case is for sale with DHL shipping from Octominer directly for $125 and $150 for the shipping and if you are going to build a nice GPU setup I really think it's the way to go, they even sell prebuilts with GPUs included for same shipment cost so that's nice if needed.
4  Economy / Computer hardware / [WTB] Octominer Case on: September 07, 2018, 04:23:44 PM
I'm looking to buy just an octominer case, the enclosed server style one, I currently have the open air but due to the wife I need to have it enclosed. I'm US based.

Thanks
5  Economy / Service Discussion / [Review] Zoomhash.com $50 used Power Supply on: September 04, 2018, 03:21:12 AM
This is a review of Zoomhash.com and their $50 used power supplies they currently have for sale, the link to their thread is here: https://bitcointalk.org/index.php?topic=4614111.0

The user Zoomhash LLC is the one doing the communication for their website, as for when I initiated the purchase of the Power Supply I went through him as their website did not have individual orders as an option yet.

Zoomhash LLC on Bitcointalk promptly had everything go over to email, I believe this goes from a social media representative to a sales representative which helps you get what you need rather than social media post.

I was put into contact with Riley who was super helpful and prompt with their replies, I was able to get an invoice in under an hour sent to my email.
Since the order is listed as "$50 ea.
1000W or more ATX PSU, 80Plus Gold rated
1200W or more non-ATX PSU for Antminer L3" I had requested a bit more information and Riley was able to get back to my emails in under half an hour, although they will have to get a tech to specify the brand if you are requesting this which will slow things down and may not be a standard part of the ordering operation.

The payment options accepted are as follows : BitPay, check, or wire transfer.
With the following note : Shipment is fulfilled after funds have cleared.

Shipping for my Power supply came from Washington and their standard is UPS Ground shipping, this was around a $20 shipping fee, if you are close I would expect less as I was on the exact opposite end of the country.

My package arrived very quickly in about two days, although I was surprised as it was in an reused Amazon box, this caught me off guard a bit but I figured this was due to me ordering an individual unit and not a bulk order. The packaging on the inside was extremely well done and I was happy to see it was extremely secured.





Now here is where the exciting part happens, I finally saw what I could not believe the PSU I received was an Enermax Platimax 1350w 80 Plus Platinum, this is a $350 PSU when new. It really seems like Zoomhash really went highend when they built out their mine with the PSU's, this go me extremely excited to really check out the condition it was in and boy was I happy with the results.


The power supplies they have set up in their mine seem to be very 12v rail focused like we would all expect:


All the stickers are here except parts of the serial sticker which could possibly hinder RMA but honestly that's a pretty low possibility as I have never been asked for that information when RMAing a Power Supply.

Here are some more photos of the outer PSU to show the condition:





Now I have compared this Power Supply with the specsheet online and I am happy to report that it came with all of the original cables, the modular ports and cables did have a small amount of dust and one broken clip but other than that it was great.

 

To be honest though if your power supply arrives with a broken clip on the modular side, make sure to not use that, poorly socketed cables can cause melting, check your spare part bins for more cables (Cautiously as mentioned by Darkstar, modular cables are not standardized, using one made for a different PSU could kill hardware or cause a fire.)   or ebay if more connections are needed.
PS: If worried about adding cables order based on the PSU model or you have a possible cable match the pinout to the PCI-E side and match every single line to the modular port, if one does not match the official cable it is NOT suitable and cannot be used.




Overall Zoomhash has been an amazing experience for getting a power supply, sure it was used but the quality for price was unbelievable, a quality brand with high efficiency without the fear of it combusting all payable in BTC and with a reputable quality customer support all based in the states.
6  Economy / Computer hardware / [WTB]Used Octominer Board, case (possibly PSU) on: July 25, 2018, 12:25:52 PM
Looking for the cost of am octominer Mobo and case, PSU would be nice too but not mandatory. I know a lot of people have liquidated their GPU rigs so I'm hoping someone will have this or similar.
7  Bitcoin / Bitcoin Discussion / So what the fucks up with China and Bitcoin on: June 16, 2018, 03:44:25 AM
So I get asked this all the time and figured I'd write an article on it, let me know what you think:

If you have any more questions let me know and I'll answer them in here about this shitty couple that is Bitcoin and China.
8  Alternate cryptocurrencies / Mining (Altcoins) / What algorithm is Bitmain secretly mining right now? on: April 08, 2018, 06:02:45 AM
We know Bitmain mines long before they announce a new miner coming out to the public, this means logically we can assume something else is being mined, it went like this:

1. Bitcoin (Sha 256)
2. Litecoin (Scrypt)
3. Dash (X11)
4. Monero (Cryptonight) - This was surprising I expected Ethereum for sure before this
5. Ethereum (Ethash)


What would be next?


I want to say it would be Vertcoin they seem like a major up and comer to me but they could never publicly sell this miner as it would cause a fork immediately, they (Bitmain) have now finally felt community backlash, they are starting to realize how painful this can be.


What other coin is being targeted or already mined?
9  Other / Meta / Mining Section change of posting rules? on: March 21, 2018, 03:19:05 AM
I used to be a big time poster in the mining section and I went back to focus on it a bit the other day and noticed today I have 5 personal messages today, all delete notices.

They were all deleted by moderators for being off topic it seems but looking back at the post this really didn't seem the case. Is there a new Moderator in charge of this section or has the section just been tightening up what post are allowed there?


I'll give a few examples:

Here is a post about the new ~1000w Bitmain miners:
The only good thing about this would be for us Americans on 110v and have room for a miner or two but this is just silly for the price. Hobbyist are growing i'm sure though so Bitmain can unload their repurposed S7's.

A post on a DIY miner by building it with all the pieces :
I remember that their old boards used to use Beaglebones as controllers, we know they used them for 1-5, anyway to just try and repurpose one of those and focus on making a firmware? The BM1384 was the chip on the S5 if I remember and I think they didn't do a shrink on the S7 but I could be wrong on that. Unless you are wanting to go ahead and manufacturer your own controller either way more power to you.

A post on if it's safe to have a miner in an area that power goes out often, replying to a post suggesting a tesla power wall:
An uninterrupted power supply would be the better solution wouldn't it? I haven't looked too much into the power walls recently but I can only assume they are quite the initial investment and unless power outages are frequent or you are starting a solar operation they seem overkill.

and finally a post of a company rolling out 3 miner models to compete with Bitmain, the 9+, 10 and 10.1:
Am I missing something or are they just going off of Bitmains Naming scheme to try and trick buyers into thinking these are newer Antminer models? Seems like a scummy thing to do, if it was just the best they don't need to name them like this.


All of these were deleted not by the thread starter but by admins, I understand if we are going for very strict post on there but this definitely didn't use to be the case and I understand if I am being flagged but I just don't get it.
10  Economy / Speculation / Over 1 million people have signed up to Robin Hood Crypto Early access on: February 05, 2018, 03:44:40 PM
Alright, lets be honest Bitcoin is down but right now just might be a prime time to get in, sure we have FUD everywhere but we have investors eyes still.

When Robinhood turns on crypto we are going to have a boom in demand, a massive one, this should really cause a rise in price. A lot of investors weren't looking to go out and open new accounts all over the place but since Robinhood already has a ton of investors this makes it easy for them.

What this also potentially leads to is other players like Etrade allowing crypto trades through their own systems.

Just be prepared for this is what I am saying, we could see a massive rise again due to this.
11  Bitcoin / Bitcoin Discussion / Stock trading app Robinhood is adding fee free cryptocurrency trading soon. on: January 25, 2018, 06:04:20 PM
This is a semi major player from the stock world adding Ceytpo, I expect this to lead to others adding if it goes well. This will definitely bring a lot of standard investors into buying a bit of cryptocurrency.
12  Alternate cryptocurrencies / Altcoin Discussion / An open source version of youtube? on: January 17, 2018, 09:20:50 PM
Youtube has essentially killed off all of the little fish, now to receive ad revenue you must have 1,000 subscribers and 4000 watch time in hours in the last year.

This kills small channels, and youtube keeps changing their terms to consistently manipulate what is shown.

We have heard for a long time that a youtube competitor needs to come and liberate people from relying on youtube/google. There is a massive massive issue though, youtube always operates at a loss, this means a startup is going to have essentially much worse odds of trying to compete and not go out of business. This has led me to believe that an open source system based on a cryptocurrency could definitely be the way.

Here is my idea:

You host videos via one of two ways by either donating cloud storage twice the amount of your upload or using a variable amount of video coin depending on upload size. People will mine these coins via hosting encrypted files which would be the videos people pull. (Spread on multiple host locations in case one goes down) Buying these coins is how an advertiser would advertise. They would have to pay a variable amount of tokens for ads on people's videos. This payment goes to the content creator while the transaction fee goes back to the miners along with the block reward.

Essentially we take Sia and youtube and mix them together, it could easily be a fork of sia with the extra conditions added to meet the video streaming/hosting demands.

This solves the bandwidth issue by paying for the storage freely trough upload space or buying tokens from miners through an exchange, content creators get paid, advertisers advertise.

Consumers would have zero change they would just go to a website type a video, get an advertisement and continue on.


Am I in crazy town or does this seem like a totally viable option?
13  Economy / Speculation / Thoughts on what's going on. ( Price related) on: December 22, 2017, 02:16:09 PM
So as we know we are going through a bit of a dip. Now let's ask why? One we recently saw a lot of money come into bitcoin from outsiders who aren't even standard investors, this means a few things. Not knowing how Bitcoin works, not having strong hands and listening to standard news outlets for information. We all know bitcoin cash crew has taken this as an opportunity to fud and muddy the waters to try and overtake Bitcoin, we have all seen the headlines, bitcoin CEO sells all bitcoins for bitcoin cash and coinbase having insider trading. (By the way why wouldn't the CEO of bitcoin cash already have traded his true bitcoin for bitcoin cash I mean he must believe in his own coin) Norwegian banks warning people making world wide headlines even though they don't understand.

Fud from random people everywhere, it's a side effect of becoming popular.

Just hold and remember for ever coin sold there is a buyer , we are having the lighting network come Q1 2018 and segwit is gaining use.
14  Economy / Trading Discussion / Fuck Kraken Fuck Coinbase on: December 10, 2017, 05:08:06 AM
Hey everyone i just wanted to say FUCK YOU to kraken and fuck you to coinbase.


Now lets ask why?


So to be fair coinbase was my old trader, and the issue with them was they stopped recognizing my bank account, kraken was a huge pain to try and get verified with. So much so they said my 1200 dpi license wasn't good enough and that i needed a jpeg photo of my license (nice joke guys). Gemini was not just a breath of fresh air but a damn relief compared to these bastards. They only needed my social and personal info and 3 days to allow my to trade. Coinbase still can not confirm my bank, I can now trade $100,000 a day (which thankfully i can use a lot of for my house down payment compared to coinbase) which is a lot more than others.
15  Bitcoin / Bitcoin Discussion / Has Bitcoin become proof of stake without anyone noticing? on: December 01, 2017, 03:35:18 PM
Now listen I'm not talking in the form of confirmating transactions but in the form of earning based on the amount held.

Bitcoin has been fork and fork planned on the main chain where you get x amount of the forked coin for the amount held at time of the snapshot.

You take these forks and sell them to increase your mainchain holdings, it's definitely a form of interest based on amount held we just don't know how much. Bitcoin cash gave us a 10% stake, Bitcoin gold I'm not sure how much and I'm hearing about a Bitcoin diamond. It seems this will be a more and more common thing that should be taken into account when investing long term.

So as we progress and forks are more common should we start to anticipate an interest earned by holding main chain and dumping forks?
16  Alternate cryptocurrencies / Mining (Altcoins) / Powering the D3 from Bitmains psu does cable setup matter? on: December 01, 2017, 01:38:40 AM
Alright time for me to look like a newbie, I just got a shiny D3 and before i flip any switches I wanted to make sure I didn't mess anything up with my coordination of cables. Using the Bitmains Powersupply you get 4 bundles of cables, two are single and the other two are 4 each for a total of 10 pcie plugs. the D3 takes 10 plugs in total, a match made in heaven.

The D3 has 3 rows of 3 and a final single pcie slot on top.

Now here is my question does it matter how these are plugged in? I am only worried since I haven't dealt with server style psu and I am not sure how the 12v rail works on this and if there are multiple rails.


Please if you have experience with this setup let me know, thanks.

19  Bitcoin / Bitcoin Discussion / Cashing out large sums of bitcoin on: August 24, 2017, 01:58:29 AM
Alright so here is what I have going on, I am trying to find out the best and 100% legal method of transferring money from our investors in China to our company in the US.

Which exchanges could I do this the quickest to avoid volatility issues, and what exchange can I sign up as a business for reporting to the IRS?
We are talking pretty large sums so higher limits would be better.

I personally have a coinbase account and I believe I have a 100,000 monthly limit (or it was something like that the last time I sold coins)

Which exchange is the best for our Chinese partners to buy high amounts from?
20  Other / Meta / Are we under a DDOS? on: July 25, 2017, 02:44:01 PM
Seems like the forum is getting laggy and throwing up error pages here and there, I say this is bitcoin related as its an attack on the site if so, or less likely the site is just getting more traffic than usual.
