If you go to Help > Debug Window > Console and type getwalletinfo into the box at the bottom, there will be some wallet info that shows up in the box on top. If it has a field labeled "hdmasterkeyid" then you are using and HD wallet. Otherwise, you are not.

Use a local watch only wallet on the server itself to give out addresses.

Yes. Shut down both Armory and Bitcoin Core. Then just copy the entire Bitcoin Core data directory to a safe location. To restore, just replace the data directory with your backup and it will pick up from where the backup left off.

You will not get positive trust by asking for it. If you ask people to give you positive trust, you will most assuredly get negative trust. You must earn positive trust. You do not ask for trust, you will simply get more trust if people believe that you are trustworthy.
First, you need to post with better quality. Post with proper grammar, punctuation, and capitalization.
Generally to get trust you need to conduct a lot of trades and in general show that you are a trustworthy person. You have to demonstrate that through your actions. Your goal should not be to get more trust, it should be to be a trustworthy and reliable person. If you are, then the trust will come naturally.

Huh? No offense but could you please show me where op mentions gambling or casino in this thread? I just re-read all of op's posts and even did word search on the page and couldn't find any mention of gambling or casino anywhere other than your last post. Believe it or not I actually happen to read before I post.
Whoops! Wrong person, my bad. There was another thread where the OP had a similar issue and he said that he was doing that because he was gambling. I got my threads mixed up. |

Now that this has happened, what recommendations does community have for bitcoin wallet type?
Do you think it was my coinbase or my multibit that was compromised?
Why don't you just use the wallet service provided by Coinbase themselves? they're one of the most trusted Bitcoin companies around. Unless you're paranoid about your private keys like some people around here seem to be. Personally I only use Coinbase, no local wallets, I've been with them for nearly 3 years now and have never had any problems. Plus they offer a few cool features you won't get with a local wallet, like no transaction fees when sending, cold storage, instant transactions when paying via BitPay. Plus your Bitcoins on Coinbase are insured against thefts and hacks. Just make sure you have a strong unique password and enable 2FA and you'll be fine. First of all, it is highly inadvisable to use a web wallet. You are not in control of your private keys. Coinbase is known to have shut down accounts and prevented people from accessing their money. They do this especially in cases where they think that someone is doing illegal activity, including online gambling. If you read the thread, you would know that OP is doing just that, gambling with Bitcoin online. He needs an intermediary wallet in order to prevent Coinbase from knowing that he is gambling so that they do not shut down his account and take his money. Edit: Got my threads mixed up. |

Quantum Computers are not any faster at hashing than classical computers.
You are very wrong. From Section 4.3 of https://www.iotatoken.com/IOTA_Whitepaper.pdf: It is known that a (today still hypothetical) sufficiently large quantum computer can
be very efficient for handling problems where only way to solve it is to guess answers
repeatedly and check them. The process of finding a nonce in order to generate a
Bitcoin block is a good example of such a problem. As of today, in average one must
check around 2^68 nonces to find a suitable hash that allows to generate a block. It
is known (see e.g. [Gilles Brassard, Peter Hyer, Alain Tapp (1998) Quantum cryptanalysis
of hash and claw-free functions. Lecture Notes in Computer Science 1380, 163–
169.]) that a quantum computer would need Θ(√N) operations to
solve a problem of the above sort that needs Θ(N) operations on a classical computer.
Therefore, a quantum computer would be around √2^68 = 2^34 ≈ 17 billion times more
efficient in Bitcoin mining than a classical one. Also, it is worth noting that if
blockchain does not increase its difficulty in response to increased hashing power,
that would lead to increased rate of orphaned blocks. Interesting, did not know that. Even so, QCs cannot do preimage attacks on hashes, they can only brute force them faster. For mining, that just means that the difficulty will increase and blocks will stay the same. For addresses, that means that they still cannot find the associated public key because they still can't find the preimage. |

That is called Trust. Green means that people in your trust list (by default this is DefaultTrust) have given positive feedback to that person. Red means that they have negative feedback. Back means neutral, and orange means both negative and positive.
The trust is only shown in a few sections. These include the marketplace and reputation.

Okay , fixed the balance issue , but now I have a transaction that originally caused this whole problem that says 0/unconfirmed, in memory pool. But it's said that for like 2 days now
Find the transaction in your transaction list and right click it. Then choose "abandon transaction". If that option is not available, then start Bitcoin Core with the -zapwallettxes option. |

I deleted my logs because someone from a similar post recommended it.
There is absolutely no reason someone would recommend you to delete your logs. They have nothing to do with this issue, and in fact have made diagnosing the problem worse. Now I only have half the bitcoins in my wallet I'm suppose to , but I did all the math from my transaction section and I should have .127 not .04 , any ideas?
Have you done the reindex? I believe that will solve your issue with the "no block source available" message. For this issue, you may need to rescan, but do the reindex first. Instructions are in an earlier post. |

bitcoin blender. i searched the name of it instead of using the url i had saved on a text file on my computer, and yeah it was the first link but i dont even think the real one showed up. i feel so fucking stupid and it was like 100 dollars so im really pissed. and fuck i had no clue they were irreversible. god
I'm pretty sure that Bitcoin blender is a scam site to begin with... |

you know what, i think i used a scam website instead of the one i usually used... what do i do now?
What website do you usually use? If you sent the Bitcoin to a scam site, then nothing can be done and the Bitcoin is lost. Bitcoin transactions are irreversible. How did you find the scam site? Did you google the website and click the first link? If so, that first link was probably an ad, and it is known that a lot of scammers have been attempting to scam people by placing ads to their scam sites that appear on google search results. These scams need to be reported ASAP. |

i sent some btc to a wallet and they wont show up.
What wallet software are you using to receive the Bitcoin? Is it fully synced? It looks like you are using a multisig wallet, which for a newbie is unlikely to happen unless you are sending to a web wallet or an exchange. If you are sending to a web wallet or exchange, contact the support for that service since there is nothing that we can do here. Confirmed means that the transaction has happened and is in the blockchain. |

Please do not make duplicate threads about the same issue.
I highly suggest that you use a desktop wallet that actually keeps the keys and is not a brainwallet (a wallet that generates the keys from a password which is what coinbin does. They are very insecure). I suggest that you use Electrum.
You need to get your private keys from coinbin. Open up the wallet and go to the "Keys" tab. Click "Show" for the private key.
Now create an Electrum wallet. Make a standard new wallet, do not choose the options to import any keys. Once the wallet is created, go to Wallet > Private Keys > Sweep and enter the private key from coinbin into the big box labeled "Enter keys here". Then click Sweep and follow the rest of the instructions. This will move the Bitcoin from your coinbin address into your Electrum wallet. Do not continue to use the coinbin address. It is not in your wallet and so any Bitcoin sent there will not be available to you unless you do this process again.

I'm on Mac and it is taking forever and a half for me to synchronize with the network to get the updated blocks. Downloaded the bootstrap.dat to have it speed up but do not see the folder where everyone says place it.
Do not use the bootstrap.dat, it is outdated and will be slower than a normal sync by just running the wallet. Library/ Applications/ Bitcoin. No Bitcoin folder which is odd. I would use a different wallet, but there is some currently being transfered. If it's possible to obtain another wallet and redirect the transfer please let me know.
It should be in ~/Library/Application Support/Bitcoin. If you can't find it, go to Help > Debug Window and click on the Information tab. There is a field labeled "datadir". That has the absolute path to your data directory. You can copy that and go there directly. It may be a hidden directory. If not do you know of a way around not having a directory? I've used the spotlight search for some of the key words but nothing comes up. Eating food with no ingredients
You have a data directory. It is definitely there otherwise Bitcoin Core wouldn't work. Is there a specific lite wallet that is compatible with bitcoin core? I have electrum and it doesn't recognize the file I exported with the private keys.
No. No major wallet exists that is compatible with Bitcoin Core's wallet format. You have to export the private keys one by one and import or sweep them into another wallet in order to spend the Bitcoin from those keys from another wallet. |

When I open any app, and click import, it only shows me MY ADDRESS... It then wants me to go to the OTHER WALLET WHERE THE MONEY IS KEPT, and SEND it from that wallet.
The problem. It's not on a wallet. Lets say the website is called marketplace.com. I bought some stuff from marketplace.com and paid $14,000. Well, they dont ship to USA so they refunded it. All I have is the private key. There is not built-in app on that website. There is no wallet. There is no interface. All I literally have is a bitcoin address.
When I try to do what you say, it doesn't let me type in an address. I can request a payment from someone, but still that requires them to have a wallet and send money to me. All I have in a private key. Nothing else.
Then you are clicking the wrong thing. Importing will not show you your address. It will give you a place to enter the private key (which you have). Either you are clicking the wrong button or you are using an poorly written wallet, I highly suspect it is the former.
Please do not make a duplicate thread. I saw that you made one in beginners and help with some more info. From your other thread, you say you have tried: I've tried Mycelium, Electrum, Coinbase, Bitcoincore, and blockchain.info. Someone can you please, please help me? I have used all of the above. This is how you sweep Bitcoin from that private key you have into Electrum. I guarantee this will work if you actually have a legitimate private key (It should start with a 5, K or L and be either 51 or 52 characters long) and are actually using Electrum. Sweeping will move the Bitcoin from that private key to one in the Electrum wallet. Open Electrum. Make a new standard wallet if you haven't already. Once the wallet is ready, go to Wallet > Private Keys > Sweep. There will be a big box that is labeled "Enter private keys". Enter in that box your private key. The address in the box below is the address that the wallet will send the Bitcoin to automatically. Click Sweep and it will move the Bitcoin from that private key to your wallet. |

So according to you BTC is not in danger against quantum computers?
of course it is and so is everything else. bitcoin's gonna be the least of your worries if it arrives and there's no preparation to counter it. Please stop spreading misinformation. Please learn about how QCs work before you go around making posts like this and spreading panic.
As has been explained multiple times in multiple places on this forum and on the internet, quantum computers pose a very low risk to Bitcoin. As Danny said, The word quantum does not mean "magic".
Quantum Computers are not any faster at hashing than classical computers. Thus they will not destroy Bitcoin mining. What Quantum Computers are really good at is prime factorization. Through Shor's Algorithm, QCs could in theory obtain the private key out of a private key. However, it is not known how long that will take as no QCs have been invented that can do that yet. It is only known that it will be significantly faster than a classical computer. While that sounds scary, it isn't actually the end of the world for Bitcoin. If you do not reuse addresses as most wallets practically force you to do, then you are perfectly safe. This is because the public key is protected by a hash, and hashes are not easily reversed by Quantum Computers. Thus your public key will remain safe, and when you go to spend your Bitcoin, the public key will be revealed but the Bitcoin will be gone so there is nothing for a malicious entity to steal. Furthermore, Quantum Computers aren't just going to suddenly appear overnight and be powerful enough to crack various cryptographic schemes. As they become more and more popular, there is a very high likelihood of Bitcoin changing the signature scheme to something that is quantum resistant so your Bitcoin will still be safe. |

I bought several things and never had an issue. A few were refunded. I was given a private key that is used to sweep it says "key to be swept". All the apps only let me import but i dont have bitcoins to import. They are on a private key, but im not the owner of that wallet. So what i need is an app that i can sweep a key. Ive had my money sittin around for weeks and im completely broke. Does anyone have an idea for me?
Sweep and import are almost the same thing. You can simply import the private the private key and then send the Bitcoin to another address that you control. You can also use a wallet like Electrum which has an option to sweep the Bitcoin from the private key. |

Hi there, download bootstrap.dat and place it in ~/.bitcoin. After loading Bitcoin Core, it will begin importing blocks from disk. Also you can to use the command line to extract the private keys from Bitcoin Core. Unless you're going to wait for the blocks to be synchronized from the beginning, export the private keys, import them to Electrum, go to the Send tab in amount hit key and send to one of your Electrum addresses. Make sure you have written seed properly in paper and in a safe place.
Wish you success.
No. Do not use the bootstrap.dat. The download will take a long time and is unnecessary. |
