I just had this problem:  I don't use a change address.  I had 0.25 BTC in one address (A).  I sent two identical transactions, one minute apart, of 0.1 BTC (0.0002 fee) to address B.  One transaction started confirming immediately.  The other didn't start confirming until the first had about 30 confirmations.  Is there a way to have both start confirming instead?

I'm not sure what ultraprune is.  I just built it from source.  I used an external HD to store the blockchain.  It was pretty slow and hogged the CPU.  Eventually I just gave up and installed electrum.

I'm sure they're busy cracking encryption trying to read suspected terrorists' emails.

It says they're not doing litecoin.

I don't know enough about it to say no, but since the private key can't be practically determined by the public key, I'd guess that it wouldn't help.

Wanted: Somebody to go back in time with me. This is not a joke.  You'll get paid after we get back. Must bring your own weapons. Safety not guaranteed. I have only done this once before.

Just because you got paid doesn't mean it isn't a pyramid scheme.  Just be wary.

A lot of those unconfirmed transaction are micro-faucet spam.  If the block size was increased they might go through easier.

I can't imagine it's legit.  I don't know how he would make such a high return.

The private keys have to be the ones that are deterministic so I'd guess no.

Well if someone gets your seed then they get all your private keys.

Yes, but it's more like replacing a word document with the backup.

I started with multibit, but am trying out electrum and I really like it.

You can use a lower fee, like 0.0002

But yeah, as the exchange rate rises the fee becomes large.

That's OK, it's how bitcoin-qt does it.

I haven't used that one, but it should be OK.  It should have a list of about 100 addresses ready to go and it'll keep your old one in case you get new coins in it.  Make sure you backup your wallet though.

What wallet do you use?  Unless you can recover the private key to your old address the bitcoins sent there are gone.   You might want to use a different wallet.

You could create one address for each pool and keep them all in one wallet.  Or you could make one wallet for each pool.  Or just have one address to receive all your funds and use the pool's account page to view how much you've made from each.  (much easier)

Your fee was 0.001 -- the 0.0921 is your change which is always sent to a new address.  Your wallet software generated this address for you and should have its private key (you need to back that up if you haven't already).

1Nu8Y6krpe31Snu7fW8TJHcAkDHKc1onQ1 0.0921 BTC  <-- you had more than you needed to send 0.86 and it sent the rest to this address which should be in your wallet

(bitcoin always empties your address when you send bitcoins unless you tell it not to)

Not if they function as an exchange where they match up buyers and sellers.
