It seems that if it was never confirmed, then it should go back in the wallet. Otherwise, it's in limbo forever. Is that even possible? It is either sent or not sent.
This makes a good point. Bitcoin isn't "in limbo." At a low level, bitcoin relies on inputs and outputs, so the bitcoin is either in the original "spot" or the next "spot." Nothing gets 'returned' and nothing 'goes back' because it is either in spot A or in B. ;-)

Thank you for your quick response...If I decide to go with Electrum, can you provide me the link to download? How do I export the private keys from the bitcoin core to electrum??
My system is old (vista OS). How long would you estimate the download of Electrum??
I hope to hear from you SOON!!!
Electrum is here: https://electrum.org/#home(ONLY download from the official sites for any of the wallets, btw) The Electrum sub-forum is here: https://bitcointalk.org/index.php?board=98.0Electrum itself is small - maybe 30MB depending on the version so it is quick to download electrum itself. As far as exporting, this has some step by step instructions: http://bitcoin.stackexchange.com/questions/4203/how-can-i-export-the-private-key-for-an-address-from-the-satoshi-client/5933#5933 : launch your bitcoin client click on 'help' in the menu bar (top right) click on 'debug window' select the 'console' tab type: walletpassphrase "your walletpassphrase here" 600 type: dumpprivkey [your Bitcoin address here] this will return the private key, you can copy it now; ensure you clear your clipboard/history afterwards

Thanks cr1776 appreciate the reply...... ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) think i am probably being overly cautious, but have already lost 2 BTC to a scam and dont want to lose any more....lol ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) I don't think you can ever be too cautious. :-)

-snip- Ok so a random 12 word password should be strong enough then ?
See the post by cr1776, I dont know. It depends on your way to select random words and the word basis or number of words. It sounds good though. and i prob have no need really to create a .conf file to be honest, but interesting to know. thanks alot for the help
Usually not, no. i used a 12 random password that i had generated from counterparty wallet for some SJCX, could that be an issue? counterwallet.io i doubt very much that the counterparty wallet stored my password....... i think that it is browser based.... ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) In theory a 12 character random password should be good enough. Is it just alpha-numeric characters? Lower case? Upper case mix? Special characters etc? (Don't answer, but that changes the math). Was the random generator that generated it really random? I think the smart advice is: if you don't need to leave the wallet.dat somewhere where someone could copy it and then try to brute force it, don't. But it really depends on the threat that you are worried about. If this is just a computer that your family is using, that is one thing. If this is a USB that you are going to throw away where someone might find it and look at it that is something different. If the wallet.dat is going to be somewhere where you have untrusted people -e.g. people you don't know- who have access to the wallet and computer at random, if you can remove it from the computer/drive etc, you'll be better off. The more bitcoins you have stored in the wallet (or the more that you could potentially have in there at some point in the future) the more concerned you need to be about where it goes. I think the main thing people have to be worried about is a virus on the computer that is stealing their credentials though.

-snip- Great help, thank you, so thats why it is always best to use a new address for sending and receiving Bitcoin ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) But its wrong!. Bitcoin core keeps (by default) 100 unused private keys and addresses pre generated for you. This would only work if you would use all 100 (change)addresses. You can change this by adding keypool=103 to your bitcoin.conf file. Ok so then it is dangerous to leave old wallet backups on computers or USB pendrives that others have access to. Shorena could you explain abit more about keypool 103 into bitcoin.conf? where is that file? i have checked %appdata% and cant see it Yes, it is dangerous to do so. Even password protected wallets shouldn't be left where others have access. People often overestimate the security of the passwords that they use and the password that they think is "good" is, in reality, bad. So while the software is good at protecting the wallets reasonably well IF you have a "good" password, if you have any significant number of bitcoins (or alt coins in an alt coin wallet) leaving the wallet.dat exposed anywhere is not recommended if you have the ability to remove it.

Random economist: Fiat use should be allowed only after a financial education course. Instead of promoting or banning fiat, authorities should educate the public about fiat. Access to fiat should be denied to those who are not aware of the dangers of inflation, confiscation, use for illegal activities, ease of stealing, and counterfeiting. :-)

So you think when they answer
They won't answer, if you look at the FAQ: https://block.io/faqSee: I forgot my Secret PIN. Can you get my coins for me, please? When you signed up, we asked you to save your Secret Mnemonic. Do you have this?
If yes, go to Settings, enter the Secret Mnemonic (ignore the Secret PIN field), and then your new Secret PIN, confirm your new Secret PIN, and click 'Change Secret PIN.' This step will also generate a new Secret Mnemonic -- make sure to write this new Mnemonic down!
If you do not have your Secret Mnemonic, we cannot help at all. We do not maintain access to your coins -- only you can access these once you remember your Secret PIN or Secret Mnemonic. You can always confirm your coins are in their respective addresses using any third-party Blockchain Explorer, including SoChain.

Yes, the block should be generated every 10 minutes but it is not. I want to build next difficulty prediction based on time value that will be required to generate next 2016 blocks after difficulty change. I want to extrapolate current block count into future and estimate this time.
You can always run Bitcoin Core and track it yourself.

Hello, i bought 10 miners, i have my rasp PI, everything is connected correctly. But the miners are flashing yellow all of them, I put the pool address and my worker username and password and it won't connect to the pool. Please help.
At the beginning i manage to get 3 of them working with the blue light, but i didn't notice that 1 of the cables that connect the miners to each other was disconnected and then i connected and restarted the miners, since then, i am not able to get any of the miners working or connect to the pool. all on yellow flashing.
You should move this to the mining section, you'll get more answers there. ;-)

I run a full node now on 0.11.2, is it possible to upgrade to 0.12 RCx and still serve the network?
Yes, just upgrade it. Depending on what you mean by "serve the network" you'd want to avoid turning pruning on.

unfortunately only chance is if owner of this address would be very kind and return you bitcoins, but chance of this is almost 0, so forget about it and try to earn your lost money
Ok thanks for your quick replies ... how would i go about writing to the owner ? no harm in trying ... no try no get ... i see those two link but lol way over my head ... thanks Well where did you get the address from? well as it was my first time i copied and paste into my email draft ... glad i did or of course i would have no record of it... No the address you send the coins to. If its not from the merchant it has to come from somewhere. A typo is next to impossible due to the checksum at the end of the address. In the rare event that typo does provide a valid address, it is unlikely to be an address for which someone has the private key needed. I suggest you check your PC for malware. There is malware going around right now that changes the address in the clipboard (where data is stored when you copy and paste) to one the villain controls, and I suspect that is what happened here. yes i did find virus and i have deleted it ... i only have free addition of avg So does that mean that the address is not traceable and i cannot write to the owner ? as that was the address it was sent to ... im sorry if a silly question i am of the understanding that all these coins are traceable... through block chain ... or have i misread somewhere and got my facts wrong ? I guess the question remains (unless I missed it above!), where did you initially get the address: 1JgLem9LPSLhy97rUXacm1bVQbf7RF2YyK Did someone send it to you?

If you look at the op_return op code (as mentioned above) you will see that the amount of text that can be included is quite small so no one will be storing War and Peace, music or video in the (main) block chain. Likewise, this has been available for a while now, was debated a lot, and there were other techniques in use to store a limited amount of data in there prior to this so it isn't anything new. Using op_return is prunable too so it does not have to be stored on every node in perpetuity. Other techniques, for example, sending to a "vanity" "address" can be used to encode data. For example, I could send to "1freecarz...." if you want to encode the words "freecarz". Or whatever. Depending on the technique, one could store some data in most (all? perhaps) other cryptocurrencies. See e.g. http://www.righto.com/2014/02/ascii-bernanke-wikileaks-photographs.htmlhttps://www.quora.com/Bitcoin-How-can-I-leave-a-message-in-the-block-chainhttp://bitcoin.stackexchange.com/questions/2631/what-are-the-key-differences-between-different-ways-of-embedding-messages-in-thehttps://bitcointalk.org/index.php?topic=1023190.0http://garzikrants.blogspot.com/2013/04/on-bitcoin-data-spam-and-evil-data.htmlhttps://github.com/petertodd/python-bitcoinlib/blob/master/examples/publish-text.pyI'm not sure why you are attacking me. I run a node part time because I think it gives me more control of my wallet. Also, I can learn more about Bitcoin by doing this. I don't think I contribute much to the Bitcoin system, because It's only run part time. I started this thread because I believe in Crypto-currencies, and I am investing quite a lot of time in learning about them. I will start investing money and building web sites when I feel comfortable with both the market and my knowledge. I need to try to anticipate the future of various altcoins, and, as a relative newbie, I am finding difficulty in doing this. If I feel that the future of Bitcoin is as a message service, then I'll switch to alternative curencies. Somebody has already posted "move over twitter", and I think that is a disaster for Bitcoin. I don't want to build a substantial holding in a currency that is offering a twitter-like service.
I've just started to download the Litecoin blockchain to expand my options. Prior to realising this risk to Bitcoin perception in the future, I intended to focus on Bitcoin. Now you can continue to attack me, but I won't be the only person to perceive this issue, and I believe it is one that should be addressed in the future.

So what's to stop a miner setting up a global public records service, and take money from customers to add records to the Bitcoin Blockchain. He gets the mining reward as well as the revenue from the business. Apart from the initial cost of mining, all the maintenance costs are born by the nodes (ie. people like me) for no reward. I'm not sure I'm prepared to accept that. I see Bitcoin as a payments service, not a registrar of births and marriages, or an obituary service for somebody's pet dog. Once that catches on, and it's probably more acceptable to the public than crypto-currency, we'll be up to 50Gb blocks in no time.
You should look at this: https://en.bitcoin.it/wiki/OP_RETURNBlocks are not *starting* to contain text, they have been, but there are constraints.

Looks like your wallet.dat size is huge (size and number of keys). Why do you have it so large? That is almost definitely the problem.
To verify, if you move your old wallet.dat (and have a backup) and relaunch it, is it more responsive?
How much ram etc is on your machine? CPU? OS?

For someone to have sworn to uphold the law like this, his actions were a disgrace. His actions should have poisoned much of the Ross Ulbricbht conviction.

It isn't even at blockchain.info now. What wallet did you use to send it?
