Indeed, you can't do this immediately but the saying "you can't double spent" leads newbies to fear/feeling scammed/posting aggressively in the tech forum.

I agree with the sentiment (too much FUD spread around in general) but at the same time it should be understood that the entire *premise* of Bitcoin was to "solve the double spending problem" (so IMO not really a useful thing to tell people that you "can double spend" as it then leads people to infer that Bitcoin is *fundamentally flawed* which is isn't).

Indeed, I used the same words than the post I replied to
That would be nice to find another word for this

For newbies: double-spending means here 'replace an old, stuck transaction which isn't accepted in the blockchain with a new one'

You can double-spend

Whilst it is *possible* it is actually in practice rather difficult to do (I tried once after making a huge mistake with fees doing a raw tx).

Any node that has seen the first tx will ignore the "double spend" attempt - making it virtually impossible to then do so after only a few seconds across much of the network.

So:
Yes we can.
But you'll have to use the search function to find the guide and to wait a bit.

The minimum transaction fee is 0BTC.
This transaction just takes longer (from a few hours to a few days).
Is there a risk that it never arrives? Could I respend it if it doesn't arrive?

No, it just takes some tiem Smiley
And you can't double spent.

The default answer is now ฿0.0001/kb for Bitcoin-qt 0.8.2 and up. But, in reality, miners charge whatever they want. If evil mega-Corp buys a ton of ASICs (or miners collude) and controls nearly all the hashing power....they set the true minimum fee.

0.8.2 Release notes
===================

Fee Policy changes
------------------

The default fee for low-priority transactions is lowered from 0.0005 BTC
(for each 1,000 bytes in the transaction; an average transaction is
about 500 bytes) to 0.0001 BTC.

Payments (transaction outputs) of 0.543 times the minimum relay fee
(0.00005430 BTC) are now considered 'non-standard', because storing them
costs the network more than they are worth and spending them will usually
cost their owner more in transaction fees than they are worth.

Non-standard transactions are not relayed across the network, are not included
in blocks by most miners, and will not show up in your wallet until they are
included in a block.

The default fee policy can be overridden using the -mintxfee and -minrelaytxfee
command-line options, but note that we intend to replace the hard-coded fees
with code that automatically calculates and suggests appropriate fees in the
0.9 release and note that if you set a fee policy significantly different from
the rest of the network your transactions may never confirm.

The fee amount usually varies, but its never very high and usually isnt over 1%

if transaction = 0.01BTC and fee = 0.0005BTC, fee = 5%

If i am correct anything under 0.01 is about 0.0005 a fee
If you have a lot of small satoshi causing it to have a lot of memory or something you could get a fee of 0.0195 or something (meh o.o)

1 satoshi per kb should bé enough to start à little experiment, then up it to 1000 satoshis see what happens.

You should listen to Birdy  Grin

I sometimes sent some BTC from my blockchain wallet without fees.
They took some time, but they always arrived.

Is the transaction time possible to predict based on the transaction fee? And is it possible that a transaction with a fee of 0 BTC gets handled right away if there is a low number of transactions in the network?
The transaction time is based on the integration of your transaction into a newly mined block.
Miners will prefer transaction with a higher fee (+some other factors like coin age, amount of Btcs,datasize), so they will include them first.
If there is a low number of transactions your transaction without a fee may be handled right away.

Btw: usual transaction fee of the qt-client is now 0.0001 (unless the Btc amount is made up by a lot of tiny transactions. If you collect dust from the free BTC sites and try to send all that the transaction will have a very big datasize)
You should be fine by using that fee.

I have to disagree with Cryptocat:
Yes, there is a chance that it will be stuck for a very very long time, especially if you are sending a tiny amount of BTC.
It is possible to double-spend the Bitcoins and the first one to be accepted in a block will come through.
(the same client won't let you make a second transaction, you could import the private key to a second one or use some program to edit a local client)

The minimum fee possible is 0, however it depends on many different factors.

I suggest reading this article: http://bitcoinfees.com
