Topic: Transaction stuck for +24hrs despite a decent fee (Read 178 times)

Well....
As much as i'd like to say you shouldn't worry, i'd be lying...
IF the sender is an honest person, chances of things ending badly are small tough, and a swift reply to a support ticket is usually a good sign.

Basically: your unconfirmed transaction (and it's unconfirmed parents) are now sitting in the mempools of many nodes. However, the default node setting is to remove unconfirmed transactions from it's mempool after 3 days. If most of the network's nodes forgot about your transaction, the network will act like it never existed in the first place... If your transaction isn't in most of the mining nodes mempools anymore, chances of it confirming will drastically reduce (eventually to 0% chance).
This isn't a complete disaster... If you save the raw transactions, you can always rebroadcast them (if the sender is an honest person or company, they might even rebroadcast unconfirmed transactions themselfs).

The bigger problem lies in the fact that as long as the unconfirmed transaction chain doesn't end up in a block, there is always a possibility the sender re-uses the unspent output he used as an input for your transaction in a transaction with a higher fee. If he agressively broadcasts this second transaction, and it ends up in a block, your transaction will be "cancelled"... It becomes invalid the second the double spending transaction ends up in a block.

But, like racquemis already said: the fee is high(ish) enough for your transaction to end up in a block sooner or later, and if the sender is an honest company, chances of things going sour are slim... I'd still save the raw transactions from the chain tough, just in case i'd need to rebroadcast them. In order to do this, look up the transactions on my site: https://www.mocacinno.com/page/getraw

The fee is 345/B so i think it should confirm eventually.

I sent a support and ticket and it was answered pretty fast. They said they didn't expect the fees to rise so fast in such a short time and recommended I should wait for the transaction to clear. It's also impossible not to receive my btc, right?

indeed... The only other option is to create a CPFP, a fourth transaction paying the fee of the 3 unconfirmed transactions AND the fourth transaction.
The basic idear is that a miner can only collect the fee of the fourth transaction IF he adds the 3 stuck parent transactions in the same block. In this case you'll end up paying everybody else's fee, but your transaction WILL get confirmed.

An alternative, political, idear is to put pressure on the exchange's support dept. They created this mess, let them fix it...

ViaBTC is real, they only have 100 free slots/hour tough, i no longer bother trying, chances of getting your tx pushed are astronomically small. In the OP's case, it's useless anyway, viabtc does not accept tx's with unconfirmed parents.

confirmtx: i've not seen any real evidence of this one working

That exe you linked to: no idear what it is, i don't open untrusted executables.

So because of the incompetent people who operate this particular exchange i could end up waiting even more? I guess waiting it out is the only option?

there are several problems with this transaction
The biggest being that it's part of a chain of unconfirmed transactions. Your transaction can only end up in a block after all unconfirmed parents ended up in a block!

In your case, your transaction will only be confirmed AFTER:
761a296f4186acf06e7569253b89c835b0b8cb2321e0ad7d0a85893639dc65b4 and 6e517de18049302ff28544dace215dd1ac4df5dd185b69f6676c1095be97ca1b

The second problem is that altough you say your transaction has sufficient fees, it has not... https://bitcoinfees.earn.com/ recommands a fee of 730 sat/byte for a 95% chance of ending up in the next 3 blocks. Your tx AND the 2 parent tx's have a fee between 330 and 370 sat/byte... I know, in fiat terms that's a LOT of money, but it just isn't sufficient at this point in time.

I recently bought off bitcoin off a local exchange and I received the certain amount yesterday@ 1pm EEST. I tried ViaBtc but to no avail and I also don't have any additional funds to pay for a tx acceleration. What can I do except wait for who knows how long? This is the tx:
