The transaction is now confirmed

Are these transferred coins now free from that "dust" as they are now in different wallet?

The transaction is now confirmed

Wow!  Congratulations.  You got pretty lucky there.  I've seen similar transaction take weeks to confirm.  Glad to hear that it worked out for you.


Correct.  It's the size of the outputs that matter.  You had a few dozen outputs that were all less than 0.0001 BTC.  You've combined them all into a single transaction that creates two new outputs.  One of the new outputs is 0.1 BTC, the other is 0.00000304 BTC.

That 0.00000304 BTC output would still be considered small enough to be a problem, but I see that you included it in transaction:

which combined a whole lot more tiny value outputs into a single new output of 0.20076942 BTC.

As far as I know, Electrum does not provide coin control.

For true coin control, you have to be able to select the specific inputs that you wish to spend.  Electrum only lets you choose which address the inputs were received at.  It then chooses for itself which of those inputs to spend. Since his wallet has both dust amounts and non-dust amounts received at the same address, he needs actual coin control to separate them.

Maybe electrum

How will I notice that the nodes have forgotten my transaction? The coins come back to my multibit?

The only wallets that I know provide coin control also require the entire blockchain.  There may be some that I'm unaware of.  Perhaps someone else will stop by and be able to tell you about a wallet that has coin control and that doesn't require the blockchain.

Correct.  That is likely to take a few days.  A few days is a good amount of time to learn how to install, and use, a wallet with coin control.

Ok, could you recommend a good wallet to me and if possible something which doesn't maintain the whole block chain as I cannot keep my machine up and running.

But first he need to wait that nodes forget his transaction, correct?

Actually the transaction has an output of 0.1BTC not 304 sat

You'll need to import the private keys into a wallet that has coin control. Then you'll need to carefully create transactions that only spend the non-dust inputs and send that usable balance to another wallet.

Finally, keep a backup copy of the wallet that has only dust inputs remaining. As the exchange rate increases over time, the required transaction fee might decrease.  If this happens, then some of that dust might become spendable in the future.

So, what can I do? I also have other coins in my wallet than those from the faucets. I dont even use faucets anymore.
I would not like to loose them!

The transaction has an output of 304 satoshi (0.00000304 BTC).  This makes the transaction "non-standard".  As such it is very unlikely to confirm any time soon.

Furthermore, this transaction has a lot of "dust" inputs. Any input that is too small becomes unspendable due to the required transaction fee.  As such, you'll find it nearly impossible to spend most of the value from this wallet until the exchange rate grows significantly and the transaction fee is reduced.

Example:

If the required fee is 100 microbitcoin (0.00010000 BTC) per kilobyte, and you have many inputs that are each less than 20 microbitcoin (0.00002000 BTC), then those inputs are essentially unspendable.

The average size of an input is a bit more than 180 bytes.  This means that (when you consider the sizes of some of the other information in the transaction) you will reach 1 kilobyte in size with about 5 inputs.  Therefore, every 5 inputs will require an additional 100 microbitcoin in fees.  Since the 5 inputs you have already included will be less than 100 microbitcoin, the transaction won't have enough value in it to pay the fees.  If you add more inputs to increase the value of the transaction, you also increase the size, which requires more fees.  By the time you've included 10 inputs that are all less than 20 microbitcoin in value you need to pay 200 microbitcoin in fees, but have less than 200 microbitcoin in value in the transaction to pay the fees with.  The more inputs you add to the transaction to cover the fees, the larger the transaction grows, and the higher the fees are.

Generally when a wallet is filled with small value inputs like that, it's because the user got them from a variety of "free bitcoin faucets".  These services knowingly pay users amounts that are too small to be spent.  Meanwhile they collect much larger fees from advertisers.  This generates a significant revenue for them while they fill your wallet with unspendable dust that makes your wallet essentially unusable.  By the time their user's discover the problem, they've already made a significant income from selling the user's eyeballs to advertisers.  They prey on uninformed newbies who are hoping to get "free money!".

TANSTAAFL!
