pm your addy. I'll share some of your pain.

I've been awol for a bit, sorry chaps.

Hello Spreadcoin Community.  I want to share my experience with you so you don't make the same mistake I made.  I recently had my wallet.dat file corrupt.  When it did I was not able to access the full amount of coins when I imported my private key.  Why you ask?  Simple.  I didn't realize that when I mined Spreadcoin each block was being sent to a new address.  For example.  The first coins in my wallet were purchased from the exchange - roughly 7,500 SPR.  No problem - I sent those to my main address.  However every consecutive block I mined went to a new wallet address which means that I never dumpprivkey on those addresses.  I lost approximately 15,000 SPR in this debacle.  The coins no longer show up - even in my back-up wallet copies.  A few fellow Spreadcoin members gave me a great idea - thank you @jjjordan and @sirazimuth and @e1ghtSpace for providing the information and helping me to understand it.  I now use the following command in my spreadcoin.conf file - miningprivkey=thisisyouminingaddressprivatekey - this works like a charm.  Every new block that is created goes to your main wallet address or whatever address you choose.  Please learn from my mistake - this one cost me about $400 USD -  
thank you - pokeytex

Edit - on a bright note - there will be approximately 15,000 SPR less on the market that will never be accessed!  That is good for all of us! 

ive been mining with 2 GTX 750 ti's for 2.5 plus years pretty much 24/7
they are very efficient . around 40 watts at wall. both still mining like champs.
switched to Spreadcoin 7 months ago. i average about 1400mhs per card (more if i overclock)
(DING! just hit a block ! lol)
i believe sp has a private miner that gets around 1900mhs  for a .1btc donation.
i paid around $150 for each card back in early 2014. i guess the price has come down these days.
check amazon. theres some for under $100.  good luck and may the mining force be with you!

I believe Gladimore was in charge of the invites - haven't seen him in a few months. The slack sees very little action as of now anyways. 

Is $500-600 a reasonable amount to get a small set up going? I may be receiving a free desktop computer from a friend at the end of this week so I won't need to use my personal computer which will be nice. And free stuff is good too! >.<

I have to look into all of those different GPU architectures. We don't currently have an AMD miner, correct?

Has optimizing the code for mining become a priority as of recently?

Thanks for the help, Georgem!

If you have something to say to your fellow Spreaders just say it here and publicly. (or use our forum)

No need for slacky backrooms...  

(I haven't been active on Slack in a long time, it's too much of a distraction, and everything discussed there can't be publicly referenced, so this is a problem.)

Howdy fellow Spreaders, how does one get access to the SPR Slack channel? Unless it's public/open and I completely overlooked...

I guess it's a question of how much you want to invest.
And furthermore, do you have a spare Motherboard with CPU etc lying around....?
I wouldn't recommend doing those experiments with your main computer.

Absolutely, I basically only buy used GPUs at this time.

Currently I try to buy as many different (OpenCL or CUDA enabled) GPUs as possible to cover all the different architectures that NVidia and AMD introduced during the last few years.

for AMD this means:

• TeraScale
• Graphics Core Next

And for NVidia:

• Tesla
• Fermi
• Kepler
• Maxwell
• Pascal

But I'm currently not interesting in buying the most efficient and powerful GPU, I just want to study the different architectures and how you would optimize code for it.

I go with the cheapest and oldest first, make it work, study it, and then buy the next highest model.
So this will take a while for me to work through them.

I'm not entirely sure yet. I'm looking for something relatively cheap at the moment. Just want to get my feet wet in the process before I pour a lot of money into it. Do you have recommendations? Are used GPUs worth buying?

Nice! What GPU are you going to use?

Is there a beginners guide to mining spreadcoin? I don't know exactly where to start in terms of beginner hardware set ups. If anyone can point me in the right direction I would be greatly appreciate it!

It was quite funny, when a person pops on TV and offers no proof that he is Nakamoto Satoshi.

That's UK journalism for you. It was pretty hilarious watching BBC news and Sky news playing his interview.

He didn't mention a single statistic or fact related to Bitcoin.

One would imagine, a man who created Bitcoin, would know a plethora of facts and statistics about his own work.

Not, this guy

Here we go again.

not sure if this helps as its a very old short thread but same issue

https://bitcointalksearch.org/topic/nevermind-solved-bitcoin-wallet-runtime-errorstuck-coins-109547

I get that error with about 5 other wallets too , very annoying, especially for PoS

Lol, no it's just the actual private key. That's all.

Haha, I see how you could be confused.

so the exact syntax is: miningprivkey-spraddress-sprprivkey - in that order with the hyphens?

meaning I need the SPR address and the SPR private key or only the private key?  It is confusing with all of the hyphens.  Thanks - pokeytex

yup. thats exactly how I've set up my spreadcoin.conf file.
yeah, I suppose if I were to be hacked I'd be out a dollar or 2.
but so far, my "penny jar" hasnt been attacked   (knock on wood)
apparently hackers are more interested in 3.5 million
ethereum DAO tokens or some such thing 

Bad news mate. If every block you mined has a different address and you do not keep the exact wallet.dat they were mined to they are lost.
If you want to mine to the same address - put a line in spreadcoin.conf with a line like that:
That is also very NOT secure. If your SPR server's security is breached and the spreadcoin.conf file is accessed maliciously you are done (your address I mean).
