Cath is like "WTF" 

I pretty much agree with all of this.

It is much better to budget with something stable like LTC.
More reasons:
LTC is well establish, the p2p network are extensive, software is mature (e.g. litecoin-qt). With prototype coins, expect problems with everything, even to transfer the coin from your wallet to the exchange bay.
There are many mining pools, the top5 are very stable, almost no downtime and great monitor interface.

Once you got the setup working and you got some experience with mining, then can you try to take your miner offline at try out some other coins.

I cannot say anything about spots, I have absolutely no experience in that.
I tried spot for 30 min, when I saw this thread, i could not mine anything descent.

There are many variables to take into consideration.
1. How much time will it take get the gear up running.
2. Can the gear run 24/7? (dont take it for granted that you can plug it in, and then it will run for 31 days, without some kind of tweeking).
3. How much the gear cost.
4. The electricity cost.
5. The difficult change.
6. The exhange rate on the scrypt you are mining.

If you can earn 1 BTC in one month with a 200-300 dollar investment, then would I say that you have found a sweet "spot".

Remember investment is always the game of risk, there are no sure thing and absolutely no guarantees.
You have to evaluate the risk vs. the opportunity for profit yourself, before making an investment.

This page is good too if you are planning in investing in gear:

Edit: Just remember that GPU mining is another game than bitcoin asic mining, since the GPU still have some value when then can not generate a profit in respect to electricity cost, then can the cards be sold used, and if you have already reached ROI by mining, then is the sell all profit.

Yeah, that should not be a problem.
I run mine on a corsair GS600.

Look at this one, if you not already know it, good for comparing cards, and some of them have powerspecs too:

Not at all, some old scrap:  I have 2 x HD7850 ~ 600 KH/s

I am only mining LTC at the moment.

I was mistaken, sorry, I tried mining a few spots to see the hash rate, but I forgot to set the intensity up, so my hash rate was ridiculous low.

What pool are you planing on using?

I don' think you cant get that card to mine SPT at 500kH/s

Great! I grabbed two more.
I presume it will be batch 1, right

BTC has definitely gone pro when it comes to mining.
There is absolutely no profit to gain by building your own rig unless you are ready to invest a large amount of dollars to invest in pro equipment and rent to warehouse to keep the gear.
Even with pro gear you need make sure 24/7 that the gear is performing optimum, since the margin for profit with BTC mining are very slim, the difficult estimation in 3-4 month basis is also extremely hard to predict.

However when it comes to LTC, then is there still opportunities to make a profit.
But you have to carefully make a business plan and budget before you start, here are some key areas:

- What equipment to buy, obvoustly it must be a AMD GPU's, find a good deal for your budget.
- Where to store the rig, you wife WILL NOT be happy about the rig in the bedroom.
- What is the electricity cost, they should be deducted from your monthly profit.
- Make a budget, and make a conservative estimation of the difficulty change over the next 6 month.
- How much can you sell your gear for, e.g. after 6 month.

If your budget gives black numbers, then are you ready to go and invest in your GPU's, get them up running asap, time to market are crucial.
If the numbers are red, then are you properly better of just buying the LTC. 

It looks like ordinary bulk capacitors (KNC's derating policy is very optimistic - if you could blow them up with a bit over-voltage).
I do not believe the capacity is critical (if they are bulks), just be sure to use 25V volt rating (or higher) so they don't blow up again.  
 

Thank you for reply's... (ofcause, doh).

OP: sorry I have messed up you thread, I guess my question about private key validation and retrieval was a bit of topic.
I can delete my posts about the private key validation if you like, just PM.

Do anybody know if a parser script exist that can run offline, to check that the public adr. correspond to the private adr. ?

It would be nice to double check that the private key and public key match, before you transfer a lot of BTC.
Ofcause you can redeem your private key - but then has the key been exposed.

I could not get Electrum to import the private key.
I tried the same private key with blockchain online wallet, it worked beautifully.

What method you use/recommend to redeem your private key?



 

The script works very nicely.
Thank you so much 

I really hope that JP is not successful in their stunt.
Normal practices is that "designs" that is already implemented cannot be pattent - but you never know with such a big player as JP, they have a army of lawyers and political influence.
Bitcoin will without doubt survive no matter the outcome, the question is if it can go mainstream with a pattent like that pending.

Edit: I do not know any details about JP patent, however I have just heard that the pattent might have been formulated before the time of BTC. Anyway, it could be good news for the cryptocurrency if JP wants a piece of the cake, time will tell.

Thank you for the info - I will try out UraSoft, the application look interesting.

Thanks for all the info, well appreciated


I have a test pc for theese kinda things, would be crazy to download a "unknown" crypto client on the same PC where you have your hot wallet.
Thanks for the advice, mate.   

Thanks you all for the feedback.


Ufasoft supports all the altcoins that I find interesting.
Looks promising.  

How buggy may I ask? Have you e.g. lost coins?

Edit: CSIS secure DNS got super paranoid when I tried to access "http://ufasoft.com/coin"  - CSIS claims that the site contain harmful material in the category "virus"
