I have a really tough method in mind.

1] Extreme 7zip or RAR the wallet.dat with a password.
2] Convert the file to hex/decimal (You may also use QR code converter).
3] Print the file and password on separate sheets.

Warning:
Reversing the process can be pretty tedious! But that's a good thing.

I need suggestions on which cable/riser/extender to go for a Radeon 295X2. The mainboard doesn't have enough room for it.
I have heard some of these 'risers' cause fires/burn the board and other circuitry.

If anyone has successfully used a PCI E extender for Radeon 290 series kindly suggest one. Thanks.

If I need more than one system to mine. I need more than one rpcuser= and rpcminer= , right? I think not. Kindly guide.

emdje: I understand you mentioned algo~s and not coins. I checked poolpicker.eu and some other websites. It seems that a lot of new ones get defunct due to lack of users.

Thanks everyone.
24  Alternate cryptocurrencies / Mining (Altcoins) / Re: An optimistic sgminer solo setup on: December 05, 2014, 09:03:23 AM
Thanks emdje for the clarification.

I have a few more questions:

1] I am getting around 750 Kh/s and I have 2 cards and will be installing a third one with same specs. Would that help or still no?

2] Is the setup of commands for litecoin/any-altcoin mining correct or do I need to do something additional?

3] Can I use the same worker username password on more than one system?

4] I can try mining other currencies but is there any real world trading or exchange in return for BTC or real money available for them? .. especially for the ones you mentioned.

Thanks.
25  Alternate cryptocurrencies / Mining (Altcoins) / An optimistic sgminer solo setup on: December 04, 2014, 09:02:15 AM
I am running a recent git pull of sgminer on Radeon cards on a Linux setup.

SETUP:
1] litecoind -server
Previously I had generated 2 LTC addresses using litecoin-qt
So the .litecoin/ directory has the wallet I suppose

2] ./sgminer --url http://127.0.0.1:<port_number> -u <my_user_name> -p <my_password>
It detects the GPUs and gives a decent 3-digits Kh/s speed. I set the GPU MAX SPEED var but sgminer still says it hasn't been set.


===========================================
QUESTIONS:
1] Is this enough (practical) for solo mining Litecoins these days?  Huh
2] Once a block is found will they automatically know to send it to my wallet inside .litecoin or is there another step/command involved?
===========================================

Thanks.

Wow! Thanks for teaching us 'Arbitrage'
I think buying from BITCOIN24 and selling to Mt. GOX won't be a task and would be quite lucrative.

My belief that 'people who know real world finance and economics would fare better than nerds who just mine', is going stronger day by day.

The day isn't far when traditional NASDAQ, Dow Jones etc. investors will take BTC and other alt-currencies seriously and turn everything around.aka wreath havoc :-P

BTW do US or other country TV channels which air stock prices Sensex of Dow, NASAQ etc. show Bitcoin prices as of today?

27  Other / Beginners & Help / Re: Basic confusion between exchanges - buying and selling on: May 15, 2013, 05:46:56 PM
Thanks both. Really shocking and helpful :-)
I wonder how many people do inter-exchange buy/sells coz Mt. Gox prices peak than every other alternative .. atleast till date I hear.
28  Other / Beginners & Help / Basic confusion between exchanges - buying and selling on: May 15, 2013, 04:58:27 PM
All exchanges BitStamp mtGOX BTC-E all show different rates of Bitcoins at any given point of time.
Is it that when you generate a bitcoin address it is assigned/locked to an exchange?

Because if it isn't so then one may buy bitcoins from an exchange and sell it to another which offers a higher price within minutes.

I am confused how does it work??

Good one Pheal.
How much role does luck play in finding a block?
And hope by multiple machiens you mean > 1K systems. That's what I learnt here.

Thanks MrBSmith.

How did you sort the issue chowderman?
What are you using currently (which tool) to mine?

I am getting 8 digit-hashes and GPU #0: (null)
Others see a Graphics card name.
I also don't see a "yay" :-(
32  Other / Beginners & Help / Re: Solo vs Pools on: May 14, 2013, 06:24:39 PM
How much is lot for LTC and BTC ?
33  Other / Beginners & Help / Re: Is nVidia CUDA fooling me? on: May 14, 2013, 06:18:58 PM
I know! Right?

Found blocks   Current shares   Score   Last share at   Mhash/s*

It's all showing - and 0. It's already been an hour !!

I'll keep it running for 4 - 5 hours and check with the Pool Dashboard if my workers have generated anything.
Hope checking after 4 - 5 hours is a normal thing and generally does generate some cracked hash value.
My system is seriously slow coz of cgminer on one worker and cudaminer on another.
34  Other / Beginners & Help / Is nVidia CUDA fooling me? on: May 14, 2013, 06:03:43 PM
I have a single nVidia GeForce 6150SE nForce 430 on Windows 8
I understand GUI miner supports only OpenCL so I am using cudaminer (which I got working after overcoming a few hurdles since nVidia somehow ignores old cards in newer driver files available for downloads]
Anwyays,
cudaminer.exe says :

Code:
[2113-05-14 2:35:18] 1 miner threads started, using 'sha256d' algorithm.
[2113-05-14 2:35:19] Long-polling activated for http://xx.xx.xx:nnnn

[2113-05-14 2:37:19] GPU #0: (null), 45907897 hashes, 762.05 khash/s

[2113-05-14 2:41:39] GPU #0: (null), 10750290 hashes, 762.23 khash/s

But GPUShark says:
Code:
GPU and memory usage
- GPU: 0.0%, max: 0.0%
- GPU memory: 66.5%
- GPU memory controller: 0.0%

So I have 2 questions:

1. Am I making cudaminer.exe use CUDA or atleast the GPU's single GPU cycle or no??
2. Frankly I have never seen 3-digit khash/sec in my life until now! Can I use CUDA with some tool supporting scrypt for mining Litecoins ?

Thanks.

HuuHachu you are quite funny :-)
These CPUs are not P3, these are i7s and i3s.

Thanks.
36  Other / Beginners & Help / Re: Solo vs Pools on: May 14, 2013, 11:44:43 AM
Where is the Thumbs up button?? I thank you all.

So what I now understand is that unless I have a 100 CPUs (1Ghz atleast) I shouldn't go for Solo LiteCoin mining.
And unless I have 5000 CPUs I shouldn't go for Solo Bitcoin mining.. right?
37  Other / Beginners & Help / Re: Solo vs Pools on: May 14, 2013, 11:15:44 AM
Thank you both.

One small query: Typically how many CPUs would I need to match a bare minimum nVidia GPU ( hear ATI/AMD is little more efficient than nVidia ones).
P.S. I can;t sell CPUs  for GPU although pointing me to a good BTC mining client which utilizes Intel's GPU would be appreciated ;-)
38  Other / Beginners & Help / Solo vs Pools on: May 14, 2013, 11:02:02 AM
I am a part of a public pooled mining for Litecoins. I have engaged 15 workers, each with minimum 4 Intel CPUs, some have 8.
Would it be advisable to do Solo Mining? Will that help me make more profits?

Also is this setup good enough for Solo Bitcoin Mining? This setup does NOT have AMD/NVIDIA GPUs.
