I am assuming you have a windows operating system. Try installing your Bitcoin Wallet v0.8.6 beta into a different folder to the one it's presently installed in. Afterwards right click the bitcoin-qt.exe and select "Create shortcut" from the list that appears. Right click the shortcut and select "properties" from the list that appears. Click the "shortcut" tab in the properties window, then look for the first text box in it labelled "target". Copy the line of text below and paste it to the end of whatever is in the "target" text box. -datadir=.Make sure you copy the leading space and trailing . from the line of text above. The text box should look something like this.  Afterwards click the "apply" button, then the "OK" button to close the shortcut properties window. Put a copy of your wallet.dat file in the same folder as the bitcoin-qt.exe shortcut, then double click the shortcut you created to start bitcoin-qt.exe running. Hopefully it should start without any error. The procedure above makes a portable bitcoin-qt wallet that doesn't use any of the files in appdata. |

Thanks! But if the electrum software gets updated, what will happen to my bitcoins? Do I have to use download the latest electrum to keep my bitcoins?
bitcoins aren't physical things... Basically, a wallet is just a piece of software to manage your private keys, generating transactions, broadcasting. If electrum updates, nothing happens. You either chose to install the update or not (which usually goes seamingly, and if it goes wrong, you just use the seed words you wrote down when you first installed electrum, and restore your wallet... The worst thing that'll happen is the fact that you lost your labels). If you chose to run an outdated version, you won't have access to the latest bugfixes, patches and new features, but usually,it's not a real problem. PS: I'm also a big electrum fan. Core might be a tad bit better, since you synced and verified the full blockchain, but electrum is still good, since your private keys don't leave your computer, and can be encrypted with a strong password and 2fa Electrum is a good desktop wallet, even better when used with a Trezor so your private keys are always kept offline. But how to find out the private keys here. Is it same as seed? No the seed is different from the keys. If you go to the address tab and rightclick on an address you can let the wallet show you its private key. Ok. Is it okay if I just save wallet, seed and password in pendrives in a safe place rather than saving private keys? Saving the seed is the most important thing. You can use it to make a new wallet that doesn't have a password if you lose your original password. However, there's no harm in backing up the wallet and password too. Make multiple backups on multiple types of backup media in case one gets corrupted, and make sure they work before relying on them. Pen drives can stop working, DVDs can get broken. If you have backups on a pendrive, DVD, and memory card then if one of them gets broken you can still use the others. No one backup media is 100% reliable. When you say "Saving the seed is the most important thing. You can use it to make a new wallet that doesn't have a password if you lose your original password. However, there's no harm in backing up the wallet and password too," will it mean we can restore our wallets that way also? Also, I know seed and private keys are different things. Saving private keys are important because if desktop wallet stops functioning or site goes offline and can so the offline wallet, we can still recover from address and private key. I think I am correct here but still I am Newbie so not exactly 100%. Besides restoring from seed you can also restore from a backed up wallet file and password. However,wallet files can sometimes get corrupted, and you can generate a new uncorrupted one using the seed. Electrum can use the seed to generate an almost unlimited number of addresses and corresponding private keys. Each time you send coins from one address it sends the change left over to a new address by default. If you only have a few private keys backed up, then make a lot of transactions most of the change left over could get sent to new addresses which you haven't backed up. There is an electrum setting that forces your wallet to send left over change back to the address you sent from, but you have to manually change the settings to make your wallet do that. If you don't alter the "out of the box" settings your wallet will send change to a new address after every transaction. But unfortunately, I have saved private keys of only one address where all of my coins are in Electrum. I have Encrypted with password also. Isn't it fine? How to fully decrypt (to encrypt later) and save private keys of other addresses in Electrum? Back up your seed first. You can use that to get all the private keys and addresses your wallet will ever make. Click wallet in the menu, then seed in the drop down list, and your wallet should show you its seed.  You can get the private key of any address by clicking the addresses tab, then right clicking an address you want, and selecting "private key" in the list that appears. |

On the other hand, you seem to be assuming that there is some kind of clogging of the network that goes beyond spamming.
Is it possible that seg wit might address some of the spamming?
However, I understand that down the road, spamming might resume because there may be some folks who remain intent on creating the impression that 2mb is actually needed - even with the implementation of segwit.
"touché"first section : normal P2P transactions. last section : PUMP. Where did that chart come from? I have been searching for a service providing mempool chart like that for a long time. |

Hello,
I need to withdraw Bitcoins urgently but i am still waiting for the transaction to be confirmed.
TXID: 1094a9a831558d83f552198d51e8710d43ab6872542c56d2d20ca8ecd2e6f0e3
Address Sending: 1BkrVnSiRAjjj31AkvuymVR14QC112gvVw
Address Receiving: 1NSdTP8J22jsxbS7nJpxyxPBnsEa752ZvM
Please anyone help me out with this issue?
Thank you.
The fee your transaction paid is too low to get fast confirmations. This website recommends paying a fee of 390 satoshis/byte today, but your transaction only pays a 150 satoshis/byte fee. https://bitcoinfees.21.co/If you wait long enough your transaction will confirm. If you want faster confirmation you could try using this service, but it's overloaded, and you only stand a chance of getting accepted in the first few seconds of each hour when 100 free slots become available. https://www.viabtc.com/tools/txaccelerator/Alternatively you could ask for help in this thread. https://bitcointalk.org/index.php?topic=1943939.msg19315198#msg19315198 |

What you said is what I mean't, but maybe I articulated it badly. I mean't someone put up that wall to start people panic selling into the sneaky unnoticeable laddered small buy orders he secretly put up. Unfortunately for him the market is so bullish that it soon became obvious someone would buy his wall if he left it up for long. His cunning plan failed. You are misreading the wall and what it represents. Simply it is a way for the entity that put up the wall to buy at below the wall price. If they wanted to sell they would sell at market price and be done with it(while creating this panic you are worried about). This really isn't rocket science. The only walls we should be worried about are buy walls because they denote a major sell off is imminent. lolololol some dick head put 400 sell wall at bitstamp fucking cunt
He keeps pulling it, then putting it back up. It looks fake to me, and I suspect someone will buy it if he leaves it up long enough. If he really wanted to ell he wouldn't keep pulling it. He wants to create panic, but it's not working. editIt's been pulled again.  |

I first tried to do a transaction with a low fee, which from what I could tell was rejected because the transaction disappeared from my wallet. After that I tried doing the transaction again with the recommend fee, yet it still says the fee I paid was too low. Is there anything I can do, or is the waiting game my only option?
Blockchain says: Transaction rejected by our node. Reason: Transaction is trying to double spend. Input 0 is already spent
VIABtc Accelator says: Transaction does not exist
Transaction I.D: c0d591a7a1eeebac52a514928e44335793b268dae3150ebf13fb1b7c85b4689f
PLEASE i got this problem and i dont know what to do, what can i do please? Blockchain says: Transaction rejected by our node. Reason: Transaction is trying to double spend. Input 0 is already spent VIABtc Accelator says: Transaction does not exist That means your transaction is trying to spend coins that were already spent in a previous transaction. What wallet software or service sent your transaction? It would help us understand the problem better if you could post your transaction's ID, but I can understand if you want to keep it private. |

1. Who has a computer that's never online?
You can use an offline linux live CD rather than an entire computer
2. How many users are aware of the risks?
The more Bitcoins a user has the more likely he will have educated himself about the risks.
3. How exactly do you send a transaction from an offline computer? Could it be that it's complicated?
You can use an offline smart phone, or camera to transfer unsigned transactions using QR codes, or you can use a flash drive to transfer files containing unsigned transactions. Your online computer creates an unsigned transaction. You transfer that to your offline computer using a QR code or flash drive. Your offline wallet signs the transaction using its private key. Afterwards you transfer the transaction back to an online computer using a phone/camera/flash drive, and broadcast it using your online wallet. It's safe because your offline wallet's private key is never exposed to the internet. |

Try downloading and running the portable version, then restoring your stuck wallet from seed in the portable version. https://electrum.org/#downloadIf it syncs then the blockchain_headers file in your current wallet might be corrupt. Deleting it and restarting electrum forces electrum to generate a new one. |

Id rather stay on classic which is tested and proven secure for me unless there's a risk of losing bitcoins because of a fork.
So is there any risk?
Not if you leave them in the your mulibit classic address until after a fork. As long as you have backed up the private key (or .key file) from your mulibit classic address they are safe. If you haven't backed up and your hard drive fails, or gets infected with a virus, then you might lose your Bitcoins. |

since the fees are low i decided to test out the replace fee option in the client.. just incase i want to buy something with bitcoin and need to use it, i figured id send some coins to see how things go.
so i sent out a tx to my paper wallet with a .0001 fee.. i then increased the fee to .0002 and it doesn't seem to be working..
the new tx with the higher fee is being rejected as a double spend.. the old tx with the lower fee is still showing as ok on the blockchain explorer.
i dunno if this is intended or not.. or whatever.. but the option does not seem to work..
the thing is tho, the details of the tx show the higher fee.. so in the end after x amount of time, will i get the .0001 fee back, or will the new tx sort of just show up?
anyways, i can see tho i cant use this option as it doesnt seem to be reliable..
also this isnt one of those my tx is taking too long posts.. i really dont care how long this one takes, as its going to a cold wallet..
EDIT
hmm it just confirmed.. and it seems to be the new fee.. so i guess it did work.
Your electrum wallet connects to a server, which is connected to a Bitcoin node. Some Bitcoin nodes don't accept RBF transactions and some do. Your electrum wallet might have initially been connected to a server that rejects RBF transactions, and later on connected to one that accepts them. Try switching servers if you have the same problem again. This thread discusses the problem. https://bitcointalk.org/index.php?topic=1740860.0 |

Yes I do unfortunately have a problem with putting myself down a lot. It's a bad habit  Is it alright to upgrade my wallet without it being fully synced. I think it would take a very long time to fully sync. When I paste my transaction ID onto a blockchain website it says that it can't be found. Is that a big problem? That probably means your wallet created a type of transaction the network will no longer accept. Have you backed up your wallet.dat yet because that's the most important thing you need to do to secure your coins. If you are using windows try using these instructions to back it up. Click the windows start button, then copy and paste the line of text below into the search box that appears, then press the enter key to open the hidden folder containing your Bitcoin wallet.dat file. %appdata%\Bitcoin This is what your search box should look like after you have copied and pasted the line above into it.  Inside the folder that opens there should be a file called wallet that ends with the extension ".dat". Make a back up of that file. Afterwards you could use these instructions to use the electrum wallet if you don't want to upgrade your bitcoin qt or wait for it to sync. If you don't want to wait you can use these instructions for switching to using an electrum wallet. Electrum syncs almost immediately and lets you spend your coins almost immediately. Bitcoin core can take days to sync. Click file, then receiving addresses. Find the address you sent coins to in the window that opens, right click it, and select copy address. Close the addresses window. Click help, then debug window. In the debug window that opens click console. In the text box at the bottom of the window type dumpprivkey yourAddresswhere yourAddress is the address you sent coins to and copied earlier. Press your enter key. The private key for that address should appear in the console window. Copy it. This is an example private key. L48toSntMVhC2az4KAQCWscrQGfPbT55yCgzM5cmx9Ao69pTdwrq Download and install electrum. https://electrum.org/#downloadImport your private key into it using these instructions. http://docs.electrum.org/en/latest/faq.html#can-i-import-private-keys-from-other-bitcoin-clientsAfterwards your coins should be spendable. |

Are you sure the fee you paid was high enough? Scroll to the middle of this webpage and look at the fee in bold under the heading entitled "Which fee should I use". https://bitcoinfees.21.co/Was the fee you paid the same as that website's recommended fee? What version of bitcoin qt wallet are you running? Very old versions can sometimes create transactions that the network will no longer accept. The rules of the network changed since those old wallet versions were released. |

Ahh cool, well I'm still learning a lot about trading, but I am currently programming a dashboard to simplify some stuff ( auto limit orders, managing funds from customer etc ). Also since this is the speculation forum, what is everyone's thought about tonight, how low will we go. 2k support or back to 1900
Well, currently, we seem to be about in the middle of a price range of $2300 to $2650. We are nearly in the middle, and it seems to be a bit less likely that we are going to break downwards out of the range before we break upwards. And, yeah, if we were to break downwards, then there would be pretty decent odds of going below $2k and $1800 would be fairly reasonable.. on the other hand, like I said, breaking up seems to bit more of a better bet - at least at the moment... and if we break above $2650 then likely we will be on our way to testing $3k. I would not rule out consolidating for 1-2 weeks either, which may cause some boredom and maybe that is slightly less odds of going up would be to go sideways within the previously described price range. It's been quite volatile recently so maybe it's time to go sideways for a while. There's no news I could find that might create wild price moves. Maybe if some big story appears it could push the price one way or the other. |

Does the new wallet have different addresses to the old wallet? Did you click the options button when creating your seed and use any of the advanced features?  The options are extending the seed with custom words, and making a BIP 39 seed.  |
