How many confirmations until i can re-send the money

[sgk]

In multibit it's possible after 1 confirmation.

where i can see that 1 confirmation in multibit ? i just see green circle then tick, whether it's 1 confirmation?
i had a few days using multibit

The circle turns green gradually with every confirmation.
With one confirmation, you can see a 60 degree pie of the circle turned green.

At 6 confirmations, the circle turns into green tick mark.

Technically you can spend unconfirmed coins, but some clients does not allow you to use unconfirmed coins. So, it's up to your client. Of course, it is safe to wait for at least one confirmation to be sure.

EDIT: Mycelium does not allow you to spend unconfirmed coins, while Electrum does. Haven't tested core/qt or other clients.

[Philipd]

at times I resend them as soon as its received. I use blockchain as wallet I'm not sure it works on other wallets

[Brimskie]

you can send the coins to anywhere even without confirmation if it is from blockchain wallet as long as there is enough fee for the transaction, however if the fee is lower than the minimum amount there will be a prompt when you try to send the coins

QT clients don't allow it. But electrum and mytrezor.com and blockchain.info do.

I remember someone using blockchain wallet tried to send some coins with a standard fee and it did not confirm for hours. Later he found out it was due to him spending the uncomformed 1 satoshi spam. This means blockchain wallet can spend uncomfirmed inputs, but that transaction may not confirm.

if you send unconfirmed coins to a certain address i assume it would need 2 confirmations to get 1 confirmation on each address?

I don't think so, for example see txhash 80bc750edfffdbd1c50116faf832aa932b8ebb5756bc08076296f381dada9096 and 6da6d4cf7cdcf362dcffd4499a44c84c5d0e09bfc47169ae4fe91dc99a3a1f77. They both have 2 confirms. (As of now I'm saving this)

As Gisado said, bitcoin allows valid transacitons to be chained and being included in a single block. I think the only limitation is, that all former transaction need to be confirmed in the same block.

You don't need any confirmation, but double spend risk is higher
So, even your client allow you to re-send your money without any confiramtion, it's better wait for a confirmation

But, some people always said 6 confirmation is necessary

If the transaction do not have any competing transactions on the network and is well propagated with enough fees, the risk of double spending should be negligible. 6 confirmations prevents most attacks but not 51% attacks, you can't be 100% safe with it.

But you are sending those transactions yourself. Whom would you have to trust then?

Or do you mean as the receiving party?

[GreenStox]

You can send your BTC away after 0 confirmations if you export the private key and use any other wallet. This is really easy so everyone should be able to do it.

Yes but then he compromizes the security of the wallet.

Suppost 1 of them goes scammer , the other wallet is still holding, if you expose the private key to both services then you double your risk of theft.

It's not a good idea to mix services just as its not a good idea to use the same password in all websites, its the same logic.

What are you talking about??? Sending a transaction doesn't reveal your private key.

No i was talking about importing your circle private key into blockchain.info, if one of those services goes to be a scam, then it compromizes the private key.

For example if blockchain.info were to go a scam, if you import your circle address there then it would be pretty nasty.

It's like using the same password on all internet websites, if 1 service is fake and scammy then all of it is compronized...

For now both of those wallets are honest, but who knows what the future holds.

Then you read it wrong. He said that he already sent the BTC from Circle to his BCI account. So he doesn't need to import anything at all.

[Reynaldo]

I can confirm that its possible to send bitcoins to another wallet from electrum without having any confirmation. It only requires 1 confirmation and it will be confirmed on both sides since it might be processed on the same block (as far as i know, correct me if im wrong)

[GreenStox]

Then you read it wrong. He said that he already sent the BTC from Circle to his BCI account. So he doesn't need to import anything at all.

How was i reading wrong? And why you say "he", i was quoting you man, why you talk about yourself in the 3rd person.

You said that export-import from circle to blockchain.info, and i explained why thats not a good idea.

Where did I write this?

[Hfleer]

You are reading into things... I said that you can export the private key from your OWN wallet, not from circle. You can't export shit from circle.
