3  Bitcoin / Development & Technical Discussion / that new wallet 10 on: January 13, 2015, 01:22:27 PM
works a treat. great work folks  Grin

updated below after using it for a few days

on second thoughts

this from mmpool thread (mmpool pays tx fees to miners - it's a small pool with long rounds and miners often rely on the little bit extra to make those long rounds worthwhile):

Block 339057 was found by f92341d8 earning them an extra 0.00783979 BTC in transaction fees.

miners are losing out due to qt users having the ability to specify very low tx fees.

I sent a tx of ~2.5BTC yesterday - and specified the 'normal' tx fee - with a tx fee of only 2230satoshi - it confirmed within 7 blocks, so took not much longer than a tx with 0.0001 tx fee.

I think that the low tx should be capped at a more sensible rate. 0.0001 was fine before, why give people the ability to reduce it by such extents and skim it from the miners?

me no likey.

6  Economy / Scam Accusations / GAW DDoSing Legitimate Cloud Mining Operations on: December 23, 2014, 03:50:18 PM
It has come to my attention that Genesis Mining is currently under DDoS, as are other legitimate cloud mining operations.
The attacks began yesterday (22December) on Nexus Mining website, and have expanded today onto Genesis Mining website.

I've been trying to gather some kind of evidence, but it's difficult to ascertain, since the attack is being orchestrated from 1000's of ip addresses.
I'm led to believe that someone at GAW thinks that these genuine operations are a threat to their Paycoin ponzi scheme and as such are carrying out these attacks.

I'm also under the impression that this is not the first time they have done this.

If anyone can help, it's frustrating for my friends who work at these operations, albeit, not a threat to the mining side (payouts are being made as normal).

Please help, whoever can. This sort form of dirty tactic is not what we need to see in crypto.
All I know is that it's not just some small-time hat doing this and that my instinct points towards GAW.

7  Bitcoin / Mining speculation / Is the S5 string design safe and was it really tested properly? on: December 23, 2014, 07:32:09 AM
I have some serious reservations about how Bitmain have gone about creating their newest miner, the S5.

After seeing the magazine adverts and watching the speculation build, it would seem, to me at least, that they are designing a miner which has a good chance of failure due to the risky design.

Bitmain have done a private batch of S3++ using the chain design on an entirely new chip, in preparation to sell the S5 en-mass.
S3++ hasn't been released to the public, so we can only presume that there are a few large farms, with vested interest, mining large scale, across the world on a private batch of S3++ miners.

The string design is a very bad method to use, after so many experienced the troubles with the Prisma from AM... and... AM had to recall an entire batch.

Sure the S5 is BMT's most efficient miner to date but it's quite late to the party, the SP20 can reach this efficiency and below with proven dc2dc stable design and... without what seems to be, by Bitmain, a risky cost cutting exercise.

I can't help but think something is not quite right here... presuming that there were problems with the chips, or the boards on the S5's for them to appear this late after advertising... having an open-top design of the casing, surely won't allow enough airflow, either?

I can't get my head around what Bitmain are trying to accomplish here, so I'm putting it out there... it's a product which has high chance of failure and I can foresee many RMA'd units.

13  Alternate cryptocurrencies / Service Discussion (Altcoins) / [GUIDE] Renting out your mining rig to Paycoin (XPY) Miners on: December 15, 2014, 07:49:27 PM
There is currently a massive buzz about the new altcoin, Paycoin (XPY).
Some people have been asking me to advise how to rent their new Spondoolies-Tech SP20 miner's hashes out, so that they can benefit from the current high rental prices which are being paid.

This simple guide will help anyone who owns an SP20 mining rig configure their miner to get the most out of this short-term phenomenon, by renting out your SP20 miners to those who are interested in mining Paycoin.

Note: I am not advising that you mine paycoin directly, rather, rent your miners out to those who wish to mine it and earn more BTC than you would normally by mining BTC directly. I am in no way endorsing XPY as a viable asset to hold.

I have set up this guide using my Spondoolies-Tech SP20 1.7TH/s miner. Currently on sale for $695 $659+shipping. I currently only use Spondoolies miners and also have SP10's and an SP31 out for rent using this same methods as stated below.

To get the best rental price possible, start by setting up your pools.
As you can see from this screenie, I have set up the pools in GUI for the SP20.

I advise that you set your first pool to hash via the proxy. So initially, if you do not already have one, you will need an account at and set your prices for each of your miners. This next screenie shows how the setup page looks, including the stratum that you should input as your first pool in your SP20 GUI miner pools list. Set a high price that you would be content to receive for the rental of your miner...

When your miner gets rented out on betarigs, stats show like this:

When your miner gets rented out on the betarigs service, it will activate upon payment and failover to the second pool when the rental ends. This second pool should also be a rental site, i'm using Nicehash.

Use / as your first failover pool. Setup of this pool is simple; Nicehash have a simple guide here:

Nicehash/Westhash rentals work on a bidding system. Where the highest bidder claims their required share of the hashes.
Prices on Nicehash/Westhash will fluctuate and you have no control over the price, hence why you should use this as your first failover.

Your third /fourth / fifth pools should be your normal BTC mining pool/pools.

I hope this short guide will prove useful, I think everyone should have a chance to benefit from this short-term phenomenon.

I will reiterate, I am not endorsing the mining of Paycoin, nor am I advising that you purchase any Paycoin and I am not affiliated with GAW in any way.
thanks for reading my simple setup guide to renting out your hashes for the most profit possible! As ever I have made this thread open so feel free to discuss it without censorship.

if you found this short guide useful, please tip me at

15  Other / Meta / Proposal: hardware manufacturers should have their own child boards. on: December 11, 2014, 10:52:00 AM
To assist buyers who may be considering mining hardware purchases, I would like to propose admins of the forum create child boards within the Hardware Section, relating to each trusted manufacturer.

This would help buyers more easily navigate when choosing which product to buy and would also allow manufacturers to host individual support threads for each product.

17  Economy / Scam Accusations /, a ponzi scheme? on: December 05, 2014, 04:14:26 PM
Of late, customers of PBMining - the 'cloud mining service' have noticed reductions in payouts, amidst continual rebuttal from user pbmining that he was not prepared to give out business details or answer any questions regarding how the payout figures are reached.

When i asked pbmining about the calculations made to produce the weekly payouts, I got this as a retort:

[quote author=raskul link=topic=418183.msg9743441#msg9743441 date=1417740319]

$per24 = ($totalHashingPower * 25 / $difficulty) * (60 * 60 * 24 * 65535 * pow(10,6) / pow(2,48));

[b]That is quoted from January, and was deleted after, as we changed our formula to include other factors.[/b]  

You initially gave a calculation in a PPS method as to how your customers will be paid. This was a good move as it persuades customers that earnings may indeed be made on a PPS algorithm and there is a possibility that you are mining.

To then simply delete the post without notice to your customers, is rather deceitful is it not?
As a customer, I had presumed payouts were still as-per that PPS calculation.
You should have advised the new calculation, instead of leaving us to notice payments were being reduced.

You will have to go a long way from here to convince those of us who - you must admit to yourself - have every right to be dubious about your practices.
I'm not yet convinced in any way that you are actually mining anything by these remarks.

I will state this one more time.  If you are one of the customers who read this formula while it was still posted in the forums at that time which resulted in you buying a contract, please e-mail our support and we will make sure you are compensated for any losses you feel that you endured.  

I don't mind being open and transparent.

i am customer #51.

your turn to be open and transparent.

Please e-mail if you feel you suffered any losses from our service.

I do not understand why we cannot discuss it here? please advise the new calculation which went into place after the old calculation was changed.
please post it here:

A - B = C

Here are the facts, as disclosed by another forum member on their thread;

Well, ISC is a PITA and just moving your mouse around costs cash, but it has some interesting information on there.
One of those companies caught my eye, specifically "Digital Mining Store". Some quick searching turned up a Wordpress site with an Asicminer USB stick on it. Say, didn't PBmining's eBay account used to sell Block Eruptors?
Another link takes us to the Saskatchewan Gazette, where we can see that Digital Mining Store was registered as a Sole Proprietorship on Aug 7th, 2013. The address is 314 33rd St, Saskatoon.

Doesn't mean anything though, so let's pull out the CC and get that registration.
Well, that's disappointing. Turns out it's some guy named Jason Boyko.

Before we pass that one off, let's try a couple more things first. Let's see who owns 314 33rd St.

Seems it's a couple people named Ryckenboer. That doesn't help.

facebook details redacted

So, we know Jason Boyko owns Digital Mining Store and lives in a house owned by someone else, but that's about it. Nothing to connect it to PB Mining at all.

Let's just do a quick check here got "pbmining" and "digital mining"...

Digital Mining (“We”) operate the company Piggyback Mining (PB Mining). We are registered in Saskatoon, Canada.

Our Ebay name is SaskatoonRoxy.
Well, that settles that.

At least when this all goes under, you know who to sue. Unfortunately they don't allow Canadian customers anymore, so it'll be tougher to find a local to push it through.

PBMining currently shows slightly over 54PH/s mining for it's customers.
I put it to this community that they are running a massive ponzi scheme and are not in fact, mining 4284TH/s
as stated on their homepage


i have made this thread self-moderated and will delete any attempt to promote or defend this scheme until 4284TH/s of mining has been proven.
please discuss.
18  Bitcoin / Bitcoin Discussion / Most Influential Person in Bitcoin 2014 on: December 04, 2014, 06:36:32 AM

Coindesk are asking for input from bitcoiners to find out who has been the most influential person in Bitcoin in 2014.

My personal opinion is that, that this year specifically, the accolade should be to someone who has striven to put bring most efficient bitcoin mining rigs to market, and allow hobbyists to stay in the game up to this point. Even if staying in the game means whatever small part we still play, we are still here, and we are still interested in bitcoin - and, we are still contributing to the network we worked so hard to raise up from the ground.

Aside from the fact that the network was always destined to go large scale, the situation we find ourselves in today has been an unavoidable fate from the very beginning and I have based my own nomination on all of the above points.

I've started this thread to discuss all the candidates that might be put forward for this nomination, and why?
please discuss.

20  Bitcoin / Mining speculation / [POLL] WHAT METHOD DO YOU USE & TACTICAL PROSPECTING on: November 10, 2014, 03:31:03 PM
A Bitcoin Miner: The Home Mining Method


i've posted this in Mining Speculation forum, although it is a form of Prospecting and is yet to be proved by more than just myself.
Thus, I would like feedback on whether this 'speculation' could be a long term method to assist home miners who have more time to monitor their shares submitted, than those who unwittingly run large farms without enough time to mine the full potential from their stacked rigs.

it poses a thought... and I have also added a wee poll to see where our preferences lie. Feel free to also discuss how the percentages may evolve over time.

thank you for reading:

I'll try to explain this for the most inexperienced of home bitcoin miners.


This guide explains how to earn more BTC from home mining than the average that a big mining farm will earn per TH/s.

Firstly you will need some bitcoin.

Plug in your miners and find a DGM (double geometric method) pool to join with other miners and find Bitcoin blocks.

recommended is
you can also use
and is also a DGM pool

You will find, that depending on the pool hashrate, bitcoin blocks may take a from few days to a few months to find. If you can resist from being put off by the length of time it will take you to earn some BTC, then choose the smallest pool (in hashrate) that you can find.

Mine until you get paid.

reinvest those earnings into extra hashpower from rental websites.
Always rent SHA256 mining rigs


recommended is
alternatively you can use
there may be others...

When you are renting hashes, do not rent from cloud mining operations that you cannot change the pool details - you will also be renting out your own rigs to other miners (keeping the home mining network alive), so sign up to the rental site and set up your pool config and proxy addresses in the rental website graphical user interface.

So, once you have been paid from your first DGM round on the pool of your choice, then activate/make available your own rigs on the rental websites (do not do this before you get paid from your first DGM round) and set a competitive and reasonable price for the rental of your miners.

Keep the failover pool details on your own home rigs set to the DGM pool. At the times when your own rigs are not rented out to other home miners, they will failover to your DGM pool, keeping your earnings somewhat consistent.

REMEMBER, you are not 'pool hopping' you are alternating between helping small home mining pools find Bitcoin blocks, and earning BTC from them and also helping other home miners earn BTC and contribute to their own home mining network. You cannot apply this method to pools which are not DGM pools but it matters not what pool type the renter of your own rigs is mining.

Here is where you will need to use some of your own judgement.
From the earnings you made on your first DGM round, reinvest the entirety into renting other rigs from the rental website of your choice. I would recommend looking at the average block generation time on the pool that you are mining on with your own home miners, and spend your first month earnings over the that time, trying to keep as steady a hashrate from your rented miners as you can.

Here is where you introduce a 2nd DGM pool to your home mining operation.

Split your hashrate between the two DGM pools, and, only if you see a profit after the end of round 2, keep reinvesting until you have a wallet of BTC that you feel happy to distribute via exchanges to people who want Bitcoins but don't or can't mine them for themselves.

It is possible, but if you can't turn a profit from round 2, feel free to email me and i'll explain my own exact method. The above is a rough guide but I shouldn't expect to hear from anyone that cannot turn a profit.



There will only ever be 21,000,000.00000000 Bitcoins ever mined. At the point when mining ends, the upkeep of The Bitcoin Network will cost nothing more in carbon footprint than running a small app on your computer or mobile device. It is recognised that the massive use of electricity used to produce 21million BTC is a stain on the integrity of the Bitcoin Mining Community, but I feel, insignificant to the value of a community powered banking system; which in itself, puts the cost of running World Banks at NIL, as they will be rendered useless.

whether you believe it or not, this is the future. There is a long way to go, but it happens.

happy mining.
