1  Alternate cryptocurrencies / Mining (Altcoins) / Size of your mining farm? on: December 11, 2016, 01:25:36 PM
I am curious of the makeup of the forum users and what size farms they have and how many GPUs they are current running.

The sizes are arbitrary but I think are still fairly representative of what the expectations would be if someone described themselves to someone else who was also a miner. I am counting the number of GPUs only as rigs can come in many sizes from 1 GPU for a gaming rig that mines on off-hours, to a dedicated 7x GPU 24/7 miner.

For example, I feel a hobbyist is someone new to mining cryptocurrencies and may be using their main rig with 1 or more GPUs to mine with. They may also have additional rigs they cobbled together from old equipment, or possibly took the plunge and setup one or two dedicated rigs.

A Micro Farm is someone who is taking a little bit larger stance and dedicating 3-6 rigs full time with 4-7 GPUs in each rig.

Small is someone who is starting to invest seriously into mining as it is doubtful at this point you would still be building out of old hardware and your purchases are geared toward ROI and making a small amount of side income.

Medium is again someone going further and looking to seriously start supplementing their income and treating mining as a side job. At this level you are probably also starting to dedicate areas of your house or property specifically for mining and either upgrading your power and maybe considering switching to 240V if you haven't already. Cooling also starts to become a concern at this level.

Medium-Large I broke this out as a separate category as I think you would still be a bit too small (at the low end) to rely on mining for a full-time income, but you are definitely looking to seriously supplement your income and invest heavily in mining. At this point even with 7x GPU rigs, you are maintaining 20-40 rigs and have probably addressed and mastered issues such as cooling, power, as well as automated much of your management duties such as monitoring, software updates, restarts, etc.

Large is someone who may very well be relying on mining for a large portion or all of his/her income. At this point you are probably beginning to add rigs in batches and starting to negotiate your purchases with wholesalers. You buy in bulk and take advantage of this to lower your build costs. You may even been looking to host your rigs in a dedicated location outside your home.

Professional is where you have mastered everything below and most likely are not only are earning all your income from mining, but perhaps hiring help as well to administer and maintain your farm. At this point you are also likely to be setup in a dedicated location to host your farm to take advantage of lower power costs and well as other infrastructure issues such as cooling, security, and a redundant internet and possibly power providers.

I have several game codes for AMD HITMAN that I acquired after purchasing video cards. These codes can be redeemed at the website.

Selling for BTC, and will entertain any reasonable offers as I cannot use them all. Post or Private MSG offers and/or questions.
3  Alternate cryptocurrencies / Mining (Altcoins) / Thermal Shock? on: December 08, 2016, 11:10:55 AM
Thermal Shock may or may not be the best term to use, but what I am referring to is a sudden temperature change that miners can be exposed to.

I live in a cooler climate and with Winter setting in the outside temperatures are starting to drop below freezing. This year, I have moved many of my mining rigs into my garage due to the tremendous heat they produce if all were left inside the house, even in the Wintertime. However, while it is a good place to move some miners to I would still like to use my garage for its intended purpose, namely keeping my cars inside. So when it is below freezing outside, my garage remains close to room temperature inside when everything is closed up. I do keep a Window open slightly but overall it is pretty cozy in there.

My worry is as outside temperatures continue to drop, at which point do I need to worry about the extreme changes? So say if it is 10-20°C inside my garage and I open one of the doors and the outside temperature is -30°C, would the sudden inrush of cold air cause any issues? The miners are inside the garage a bit, along inside walls, so I assume there would be a sort of "air bubble" protecting them somewhat, but there would still be a significant rapid decrease in temperature.

So my question is is there a safe tolerance or is it any concern at all? My one thought is to keep more windows open and try to keep the average ambient temperature lower all the time, but on the coldest of days (it can get as low as -40°C on extreme nights where I live) I think I would still have a significant temperature drop should I open a big garage door under such conditions.

Any thoughts or experience on the matter are appreciated.
4  Alternate cryptocurrencies / Mining (Altcoins) / What (Ethash) MHash/sec is it better to switch to solo mining? on: October 02, 2016, 03:11:58 PM
I am thinking of maybe switching to mining solo or setting up a private pool to point to for me and my friends. I was wondering if this is still feasible and at what hash-rate(s) one would need to make it more practical versus pool mining.

Say what would one need to find roughly a block (5 ETH) per day? The calculators show roughly 1GH (1000 MH/sec) but would like to hear from anyone who is actually doing it.
5  Alternate cryptocurrencies / Mining (Altcoins) / Question on PCI-E USB Powered Risers VER # on: September 23, 2016, 09:16:25 AM
I am looking at making a purchase of a dozen or so of these, and noticed they seem to have different versions as shown in the images below. My question is does this VER # have any difference on quality, as in VER 005 is later and perhaps better (or worse) than VER 003?

Looking at the USB Risers I currently have, most are the Ver 003, with even a few are Ver 002. I have one or two of each, out of dozens that are bad, so I am interested if anyone has any experience with this. Obviously looking to find the best quality ones I can get. The price seems to be mainly differentiate between the USB cable lengths more than the version of the board, so just looking for something I can key off of while making my selection.


6  Alternate cryptocurrencies / Service Discussion (Altcoins) / Warning: was Hacked on: May 09, 2016, 02:47:04 AM
Be careful if you downloaded the wallet from the website within the past 2 weeks:

It appears this only affected wallets downloaded from Litecoin.COM and not Litecoin.ORG, but you may want to take actions to be safe in either case.

Dear /r/Litecoin community, was compromised: between 31st of March and 18th of April, and has been compromised until today. The site was serving virus-infected downloads for Windows and OSX using a Javascript injection. The attack happened due to a configuration error with the database, allowing someone to enter malicious JS into the template.


Please remember ​to change ALL PASSWORDS​ ASAP, as the attacker may have stolen them from you.

Site will be back up tomorrow. We are sorry to tell you this.

Not sure of you seen this yet or not, but it is an interesting and positive news piece for Ethereum, especially from the NYTimes.

Ether launch
Posted: March 12, 2016

Bitfinex is pleased to announce upcoming support for trading Ether.  While we are generally wary of adding new digital assets to the platform and believe that Ether’s future as a store of value is quite uncertain, it is, nonetheless, hard to ignore the Ether trading volumes at other exchanges and the many requests we have received from our customers to add Ether trading pairs.  As such, we will begin trading Ether against both US dollar and bitcoin on Monday, March 14th at noon UTC.  Starting immediately, however, customers will be able to deposit Ether into their exchange wallets.

It is our plan to allow shorting and margin trading on Ether as soon as we are comfortable with the book depth and availability of Ether for lending, but that will depend on the community’s support for Ether trading on our platform as Bitfinex itself is not a market participant in its own markets.  Assuming strong adoption of Ether trading on our platform, we could enable shorting and margin trading in less than a week.  We do not yet know what sort of leverage ratios we will permit on Ether, but given Ether’s substantial volatility relative to bitcoin, we may, in fact, initially allow less leverage than we do on bitcoin.

In order to encourage market making to help jumpstart our Ether markets, we will be offering introductory pricing on both Ether pairs.  Through the end of March, it will be free to add liquidity (market maker) and 20bps to remove liquidity (market taker).  Trading volumes in Ether during this time will not affect volume tiers for bitcoin and litecoin, but after March, Ether will be part of the existing aggregated volume pricing tiers.

We are also actively pursuing the addition of Euro trading pairs as well – we will naturally keep the community apprised of any further developments.  Once again, we thank you for your continued support as we strive to deliver the best in cryptocurrency trading.

10  Other / Meta / Questions on making a "guide" thread topic on: July 25, 2015, 05:41:08 PM

I am considering creating a new topic on the forum that I would like to become a guide for new users, such as myself. I have a few questions of the forum rules and best practices though, as I would like to avoid any issues by starting out right.

1. If I create a new topic, can I make the OP with minimal text and right away reserved the first few response myself? I was thinking something like a brief description in the OP, then maybe 3-4 replies reserved with placeholders, such as the word "reserved", so I can later back-fill the guide without it being too unwieldy in one post. I anticipate the guide will become quite lengthy and breaking it up into different replies would make it more manageable and easier to read.

2. Is it a good idea to make it a self-moderated thread? I seem to sense there is some debate on this, but I would like to keep the thread clear of any unnecessary trolling or other detracting posts. I would keep constructive criticisms, etc., but many threads I see deteriorate to the point the original intent gets lost. Or does using a self-moderated post detract from the thread creditability?

3. I have read the rules and feel I have a good understanding of do's and don't s, but if anyone has tips to offer that would be great.
11  Bitcoin / Bitcoin Discussion / Bitcoin Wallet Questions on: July 13, 2015, 08:24:47 PM
So as I understand it, each public address that I see in my wallet is actually just way to credit coins to a private address. So if I had a wallet with a hypothetical 100 BTC in it, is it safer to store it all in 1 address or break it up into different addresses? Do I need different wallets or is just having several addresses more important?

I understand if my computer gets hacked, etc., I could lose it all, so it is safest to store on PC that is not used for other things. My question concerns more if the private address is compromised, would someone get all my coins or just what was on that private address?
