Title: Transaction unconfirmed since January 5th 2018
Post by: thisFame on January 12, 2018, 05:06:23 PM
It has been stuck since Jan 5th and has had 0 confirmations.  Please let me know if you can help.  Thanks!

This transaction is from an exchange and it has just been sitting there.


Is there anything I can do if I'm not the sender of the transaction?  I'm one of the receiving addresses from the exchange.

Not really, it's a very big transaction with 0.1BTC in fee already. It would cost a lot more to accelerate it.

My problem is that my wallet spent coins from this unconfirmed transaction.  The transaction using the unconfimed tx is this one:

https://blockchain.info/tx/b05b58809252eb0f8800dd2dced9d3794c73893e2c4265b8851c4ab53a632070

The coins from the first transaction make up only a fraction of what I spent in this one.  Are the coins involved in my second transaction held hostage until the first transaction confirms?  Can I spend the confirmed coins in the second transaction's input list even though they are sitting on the second unconfirmed tx? 

If my wallet didn't use unconfirmed coins, then this whole thing never would have happened.

And a final question, will the first transaction ever be confirmed anytime soon?

Fee is big but inputs are also big. (600+) In your case your fee is 103.36 sat/B a bit small.

You can thank coinbase for spamming the network with many tx's.

If you want instant confirmations you'll need to pay like 0.4-0.5btc's nowadays. I know that's insane.

Which wallet do you use? I sometimes spend unconfirmed change, but only from my own transactions. I would never spend an incoming transaction before it's confirmed.

You could abandon this transaction, and try to broadcast a new transaction without the unconfirmed input. How you can do this, depends on the wallet you use.
My advice (in general) is to Enable coin control features and always manually choose which inputs to use for a transaction. If you know what you're doing, this puts you in complete control.

Maybe. Dropping the transaction and double spending the other inputs normally works, but normally you'd do that to a transaction with a low fee.

Correct.

Fees (https://btc.com/stats/unconfirmed-tx) for a fast transaction have been relatively low today. If miners find a few blocks with not much time in between, it can drop low enough to confirm. In general fees are lowest on Sunday, so it could confirm in 2 days.

I am using the Ledger wallet for my Nano S.  I think I understand the inputs/outputs now.  I will see what happens on Sunday.   Thanks
