Sorry if it is in the wrong section.
I've made a tx to send about 0.06 BTC to multiple destinations and got a ~0.03 BTC change for myself. However since I've forgotten about the stress test, I've paid only 0.00002 as fees and it don't confirm for 5.5 hours. I've heard somewhere else in this forum that paying extra tx fees from one of the outputs can make the tx confirm faster. Is that true?
can you please post your TX here?
anyway (as Sebastian mentioned above), there is service called bitundo which may help.
http://www.bitundo.com/index.html and as others mentioned, you have to wait and yes, it is very annoying, non-comfortable at all and hope that developers will somehow react to this..
Doesn't Bitundo have very low hashrate? They would be pretty bad idea as it would take them a long time to mine a block.
Now my tx still don't get a confirmation and I'd like to send it away now. However my wallet don't let me to spend an unconfirmed output. Where can I make a transaction with unconfirmed output with a higher fee, such that all transactions can be confirmed?
You have to wait for the inputs to confirmed first before your subsequent transactions can be confirmed. If you're using Bitcoin Core, there's a option in the preferences to allow you to spend unconfirmed inputs.
