Thank you DannyHamilton and shorena for your answers
Well, tbh, I still don't fully understand what I am providing with mining that I get those coins (I write coins because atm I have bitcoins and litecoins), am I on the right track when I would say that 'unconfirmed transactions' get confirmed by using software and resources that I provide through my computer?
Well Danny gave you an exact answer  The miners confirm the transactions and provide a certain security to the network. The more hashingpower the miners have the harder it is for someone to doublespend coins. As far as the first 3 questions, I also have a Litecoin wallet, that has no problems with connections to Litecoin network, only my Bitcoin wallet has this problem I and don't think it has anything to do with my DNS or my provider :/ Anyway: https://en.bitcoin.it/wiki/Securing_your_wallet#Making_a_new_walletThis helped! In some way, I managed to run 'old' wallet and I can see my bitcoins there  but since I still have a problem with sync and I can't send them to my newly created address on new wallet And from what I understand, all I need to do is make regular back ups and my wallet.dat file IS THE FILE I want to copy to a secure place Much more clearer now thank you! All I need to solve now is how to get the sync process up and running again... That sync problem can have several causes. Its hard to say. Might be a firewall that is blocking outbound traffic. Here is a list of nodes: https://en.bitcoin.it/wiki/Fallback_Nodesthat should be online all the time. If you are not sure wether your ISP uses ipv4 or ipv6, try both. Try adding some of them manually and see if you can get a connection. You can also try to get a connection via tor. You can also make a list of nodes in your bitcoin.conf and run the client with -conf=<path to your config> as was posted in another thread. Path is for windows, Linux/Mac would be different. -snip- I'll teach you! 1. Go to C:\Users\User\AppData\Roaming\Bitcoin 2. Open bitcoin.conf. 3. Add the following lines to it: addnode=137.116.225.142
addnode=85.214.251.25
addnode=67.186.224.85
addnode=88.198.58.172

im currently using ubuntu OS for my core .9.1 wallet and i could not for the life of me find my wallet.dat..
-snip-
https://en.bitcoin.it/wiki/Data_directory#LinuxYour wallet.dat should be in ~ refers to your user folder which you are usually in anyway when you open the terminal. If you are using the GUI Filemanager folders starting with dots are hidden, so you have to enable "show hiddens files". With the newer Ubuntu versions the bar where you find the option is usually at the top of your screen and not at your window. They might have changed that again though, not sure. |

Hi!
I have just recently joined up to whole Bitcoin community and I got some questions it would be nice if someone could help me / clarify few things to me.
Ill try my best, but some of your questions are probably best answered by someone on site 1. 0 active connections to Bitcoin Network in wallet Bitcoin Core version v0.9.1.0-g026a939-beta (32-bit) A)The first time I had this problem was with v0.9.0 I somehow managed to reinstall Bitcoin Core wallet = I ended up losing little sum of bitcoins that I had and had to wait again for that long sync, so I guess I installed a new wallet on my computer, is that possible and does anyone know how I can retrieve my coins? B)The second time I had this problem with current version this helped: http://bitcoin.stackexchange.com/questions/12265/0-connections-now-but-i-had-been-using-bitcoin-qt-for-a-while-without-problemsNow I have the same problem, and the solution from above doesn't work, wallet won't sync as it has 0 connections, I am 5 days behind The problem described in the link is about someone mining bitcoin. If you have problems with your DNS, contact your ISP (or whoever runs your DNS if you changed that) 2. How to use back-up files
So, when I go to File --> Backup Wallet --> I create a new .dat file, after I do it it gets a 'locker' and fades, I can see the file as I am doing backup and all backup files I created in the past, but I can't see those when I try to find them again browsing through my files on computer
That means I don't know how to start backed up file, because I don't know where it is (or better said I do know, but I can't see and run it)
You can choose the place where you save that .dat file. Choose a place that you can find it. Here is a list where your wallet usually is https://en.bitcoin.it/wiki/Securing_your_wallet#Making_a_new_walletYou can just copy that file somewhere else as backup. It makes now difference if the programm makes a copy for you or if you do it yourself. "run it"? The wallet can not be run itself, its just a file containing your valueable data, not the programm itself. 3. I want to put my coins to a safe place, make a physical backup, like on usb, how do I do that? And how do I place those back into my wallet? I have been reading about this but it is all so complicated, I really need some help and advice on this one
The "coins" are not stored in your wallet, but the private keys that allow you to spend them. So if you secure your wallet.dat you secure the coins. You dont have to place the wallet.dat back, unless the file is corrupted for some reason. You should make sure that you make backups on a regular basis, because bitcoin core generates new keys (and addresses for that matter) from time to time. As long as your wallet.dat has a reasonable strong password, all you need to do is copy that file somewhere safe (USB Sticky, etc.). |

0.7 experience/day (everytime you work)

Lets run that through Excel and see how many days Id need without paying anything and ref'ing anyone myself. Hmm depends on how many digits the take into account, but lets assume its 8. After 5 days you have 2 exp After 10 days you have 2.55 exp After 15 days 2.72 exp After 20 days 2.77 exp After 30 days 2.79722701 exp and you wont get much more After 90 days 2.8 exp (you loos .7 exp each day and gain .7 exp each day) Note: this assumes that you get .7 first and lose 20% later, not the other way around, but it wont make much difference otherwise. Everyday you get at least 0.7 exp and each day exp falls 0.3%.. so you wrong. Oh its 0.3% not 20%... k, lets see So ~10 exp after 15 days and, 100 exp after ~ 188 days, 1000 exp after NaN. 1000 exp cant be reached with 0.7 gain per day and 0.003 (=0.3%) loss per day. Hmm, so 15 days for 1 transaction fee.... |

This is indeed a good read, but if you read between the lines they still write about money in a way that bitcoin is money. While this is only one possible future, if we go there, it will be through a phase of transition. Money will not be useless even if we arrived at the p2p society the article envisions. There will allways be use for something that holds value. When I brew beer (great craft, people will allways needs drugs ) and want to trade it for something else, the person that wants the beers might not have what I want. Money itself is not the problem, as the article points out. The taxation is focused on the "wrong" things and a system based on interest can not be sustainable in a finite world. If you are interessted in topics like these I encurage you to read "the ecotechnic future" http://www.amazon.de/The-Ecotechnic-Future-Envisioning-Post-Peak/dp/0865716390Great insights on our society and possible transitions to a more sustainable living. |

If someone else has the same private key both of you can spend the coins that were send to the address that belongs to that key.
Chance of a collision is extremely low - you'd be more likely to win the lottery 10 times in a row than you would have a collision so I wouldn't worry too much about it. Not sure about the lotteries you play, but I think the chances are even worse. I wasnt trying to hint at collision, but rather at "be carefull you take proper randomness" since so many "brain wallets" get "hacked". Probably could have been more clear there. E.g. this address https://blockchain.info/de/address/1JwSSubhmg6iPtRjtyqhUYYH7bZg3Lfy1THas the brain wallet seed "correct horse battery staple" because people love XKCD (rightfully so) https://xkcd.com/936/There are even JavaScripts that generate you passwords like this http://correcthorsebatterystaple.net/But this does not allways lead to higher security as shown here: http://www.reddit.com/r/techsnap/comments/18ezb6/correct_horse_battery_staple_really_a_strong/On the other hand 16 random(!) words might be easier to remember for you than a 20 char random(!) password. |

I just started www.pieceofbit.com as an informative website to help beginners learn a little more about bitcoins. I am going to try to run the purely on referrals so that I won't have to overload the site with ads. I have the obvious sites listed where they can earn free bitcoin and some information. My question, how does the site look, and is there any other information/sites you think I should add for newbies. Hello there... u may like to add www.CoinLearn.org under faucet list... Thanx Just added Coin Learn to the site with a review. You should review that review, coinlearn is AWoL and didnt pay.Edit: coinlearn paid |

Would the private key be in an old version of bitcoin - 0.86 .
I deleted it and did a fresh install of version - 0.9
The private keys are allways in your wallet.dat no matter which version. I dont think the wallet.dat gets deleted while uninstalling. If you however just deleted the folder with the wallet.dat, your coins are gone. |

Hello all in my understanding of wallet.dat is that it contains the keypairs belonging to all "addresses" that a wallet eg . bitcoin-qt/core randomly generated upon creation of the wallet.? (100 addresses for qt?)
what I'd like to know is how the bitcoin pros out there find your "specific priv key for a cold storage address 'A'" within your wallet.dat..?
for example...i have read threads where people spoke of etching their "priv keys" on tungsten blocks or other really creative methods of long term unburnable storage of priv key. im assuming they somehow enter into their wallet.dat and identify the specific private key for their address?
Nope that would make no sense. The added security of "cold storage" or "paper wallet" is that your private key was never online. Thus it is not one of the private keys from your wallet.dat that you get from bitcoin core. You "just" make up a new private key. There are tools for that ( see https://en.bitcoin.it/wiki/Paper_wallet ) or you can just make up a key directly (see here https://en.bitcoin.it/wiki/Private_key for details on the format). Be carefull though! If someone else has the same private key both of you can spend the coins that were send to the address that belongs to that key. can anyone elaborate? thanks all for your help Hope this helps. |

I only have Paypal and no sites exchange for Paypal. Also I have a Amex Gift Card but no one will accept that either. Other than that I have no way of paying.
How can you have "only paypal"  How do you get money into that paypal account? |

Hey guys so I am in desire need for $3 in bitcoins. I got $1.5 but I am not gonna ask you guys for bitcoins. I am just gonna ask for websites that you can get free bitcoins fast and easy? Best ones? Ones you suggest? Thank you Free money? Fast and easy? Nope sorry, only easy but takes time (faucets, renting your signature), hard work (service section of the board) or hardware (goods) |

Thanks for your help! Thing is I'm generating a new address for every transaction for will the private key be the same for all of these?
No, a new addresse comes with a new private key. Also once I get the private key will everything remain the same in the client?
Yes, you just get a copy of the private key. Well if you lose that you might notice that your "available" amount of BTC is deminishing, so take care of the key Can I use it as normal?
Yes, you can use the wallet as you used it before. In case you want to backup, you should not backup the private keys, but the wallet.dat. |

Thanks for the replies,
How do I reindex? This is my first time having any technical issue
Windows: - win + r - cmd - click OK - bitcoin-qt -reindex sometimes you have to go to the folder first e.g. cd \Programm Files\Bitcoin Linux: - open terminal - bitcoin-qt -reindex |
|
|
|
start bitcoin core -> help -> debug window -> console: - help to see the list of commands and how they work (or see here: https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_calls_list ) - walletpassphrase "password" 120 to unlock your wallet, 120 is the timeout in seconds befor it locks inself again. 2 Minutes should be enough - dumpprivkey "bitcoinaddress" to get a private key to a given address |
|

I'd just re-download the blockchain. That will at least solve the problem, but there might be a faster way, I don't know.
-reindex will only download the damaged parts, which: is faster |
|
|
|
|
try running it with -reindex from shell
|
|
|
|
No virus?
When in doubt, dont download |
