Export your private key

In bitcoin-qt: http://bitcoin.stackexchange.com/questions/4203/how-can-i-export-the-private-key-for-an-address-from-the-satoshi-client

Then use something like http://brainwallet.org/#tx  to make the transaction (make sure to change the destination address)

Re: Private Keys vs. password

Your private key is an encryption/decryption key known only to you. With this key you are able to do everything you can with a bitcoin address (spend, sign etc).

Using bitaddress.org:

Paper wallet - WITHOUT BIP38:
You are only given private keys that you must store

Paper wallet - With BIP38:
Your private keys are given encrypted and you must store the encrypted private key and the passphrase

Brain Wallet:
Your private keys are determined by the passphrase alone so you only need to store the passphrase (passphrase needs to be very strong to avoid brute force attacks)

Re: How do you empty a wallet to as close to zero as possible?

Use brainwallet.org to send your transaction. Make the fee 0.0001 BTC and the send amount your balance minus the 0.0001 BTC fee.

That IP is running a bitcoin node with very high traffic.

You also can't trust blockchain.info's estimated time. That transaction was included in block after 137 minutes

Re: Please help, forgot miners fee and need 3 confirmations (still unconfirmed)!

I think once I get at least one confirmation I can no longer double spend and will have to wait for the 3, which could take forever!

Every time a new block is found (approx. 10 minutes) a conformation is added to everyones transaction in the block chain. Only the wait for the initial 1st conformation is long. So if your transaction gets 1 confirmation consider it 3x confirmed in 20 minutes.

Re: Do your bitcoins die with you?

If you want your family to have access to your funds after you die you could store your private keys in a safety deposit box. Your family could gain access to your safety deposit box after you die by providing a death certificate.

Re: Coinbase iOS app

Will the app still be supported?
The app will not receive any more updates. Coinbase could make the decision to drop support for the existing iOS app users at their discretion.

Will the app be susceptible to vulnerabilities?
Coinbase does not store private keys on the mobile device so no one can spend your funds without verifying with coinbase's server. I can't remember if the iOS app has 2 factor authentication. If it does you should be safe from future vulnerabilities.

Should iOS users abandon Coinbase app?
That decision is left to the users.

Re: How do I make a bitcoin faucet?
by
DualSignal
on 17/11/2013, 01:02:12 UTC
You need to be running an instance of bitcoind or use a 3rd party api to send bitcoin.

I would recommend against using cookies for a faucet as they can be faked.

I don't think running 11 ASIC USB Block erupts from a hub powered from USB is good enough. Read feature number 7.

Large devices (projectors and prints etc.) need to go with the power supply (required to buy separately).

I't appears that there may be an attachment to the hub that would power it via mains electricity.

Re: Is Blockchains 'quick send' option flawed?
by
DualSignal
on 14/11/2013, 02:07:35 UTC
The wallet probably determined that the transaction may be safely sent without a fee because of these conditions being met:

  • It is smaller than 10,000 bytes.
  • All outputs are 0.01 BTC or larger.
  • Its priority is large enough

Quick send automatically chooses the details for the transaction. If you want more control over your funds then use the "Custom" transaction type which allows you to set your own miners fee for the transaction so it may be included in a block quicker.

Get Hex transaction from blockchain.info

How do you get the raw transaction in Hex format, from a transaction that is unconfirmed, and I didn't make, but appears on http://blockchain.info in a format that allows it to be passed into http://blockchain.info/pushtx when it is dropped from all miners memory pools.
