Newb needs help with Mycelium to Coinbase transfer

[groovyclam]

Hi everyone,

I have a Mycelium wallet on my phone with the equivalent of just £45 UK pounds in BitCoin in it ( at current exchange rate ). I wanted to cash this out so I opened an account at Coinbase to sell the BitCoin.
I then picked the "receive" option at Coinbase and it made a QR code on screen and on Mycelium I chose "send" and one option in Mycelium is to use QR code capture for where to send to, which seemed to work ok ( i.e. Mycelium captured the Coinbase QR code ok ) and I sent all the Bitcoin in my Mycelium wallet in the transaction.

I did this about 11 hours ago and I've had zero confirmations in that time. Is this usual ? Is it because the miner fee that BitCoin says on the transaction detail is 0.0000026 BTC 1 sat/byte ? Is that too low ?

There is an option in Mycelium to rebroadcast the transaction. I choose that, but got the message "Something went wrong. Exchange transaction id is null"

Basically I don't have a clue what is, or isn't, happening now.

Do I just have to keep waiting or does that error message from the rebroadcast mean something worse ?

The fee rate right now for high priority to get your transaction confirmed fast now is 6 say/vbyte. You can check that here: https://mempool.space/

1 sat/vbyte is too low right now but the mempool will later become less congested down to 1 sat/vbyte again.

I am not using Mycelium and I did not recommend it after I tested it like 3 years ago and one of the reasons I did not recommend it was because you can not increase the fee. I mean RBF. But maybe it is having it right now, I do not known.

If not having RBF, just wait is my advice. Or if the transaction has changed (bitcoin sent as change to your wallet in the transaction) , you can rebroadcast the change in another transaction back to the address on your wallet using higher fee rate. Or at least let the coin in the transaction has part of the change using higher fee to rebroadcast it, but you will have to use like 11 to 12 sat/vbyte to broadcast it.

Another option is to import the seed phrase in Electrum, wait for 2 weeks for the transaction to leave the mempool and you will be able to rebroadcast the coin again but I think the transaction would have been confirmed before 2 weeks.

I guess I'll just have to wait 2 weeks and see if the transaction goes through in that time.

Am I right that the Bitcoins will come back to my Mycelium wallet if the transaction isn't confirmed in 2 weeks ?

I guess the transaction will likely be confirmed. You can be patient about it and see what will happen.

If the transaction is not yet confirmed after two weeks, import the seed phrase on Electrum and you will see it. If you do not see it, just manually change the servers on after the other and be checking the transaction in the history until you see it change from unconfirmed. Most node would probably have dropped it by that time. I do not know much about Mycelium wallet but maybe it can work too but I am not certain although that is how a wallet should be.

I do not know if by checking the transaction Mycelium will be rebroadcasting, do not open the app for the time period. It is not like that on Electrim.

Considering the time you made this post and the 11 hour interval you mentioned it's roughly around 02:00 you broadcasted the transaction in US time. That should be in the earliest periods of the morning and since its not around business hours fees should be pretty low during that period.

I don't think it should be weeks before getting confirmed. If it still isn't by now I suggest you load up your seed on Electrum check out the MEMPOOL average fee rate at that time and bump your fees like Charles-Tim mentioned. It's been quite long I used mycelium so I can't really remember if they allow bumping. Rebroadcasting wouldn't help much especially if fee rates are still high.

Check the transaction hash via mempool.space and see if it's the RBF flag is enabled. If it is, you can easily bump the fee to an optimal fee rate like 3 or 4 stats/byte and the transaction maybe confirmed in the next few blocks.

Mycelium wallet is also buggy at times, it would be good if you imported your account to wallets like electrum and continued your transactions from there.

I doubt if the wallet is now having RBF. This is what I saw on the website:

BTC Transactions Management
HD spending accounts and Single Address saving accounts
SegWit: native (Bech32) and P2SH compatible
FIO Network features
Handy address book
An extended selection of exchange rate sources
Convenient cryptocurrency and fiat currencies denomination
BIP-70 support (payment requests, execution of external payment requests)
Indication of unspent outputs for each bitcoin account
Advanced transaction history: complete transactions details (block height, number of confirmations, inputs/outputs, miner fee, timestamp, incoming/outgoing tx indication, tx hash), custom text labels, exchange rates (corresponding to selected fiat currency), tx history export to CSV files
Several blockchain explorer options
Option to display derivation address path for BIP44 HD accounts
Bump-fee option (child-pays-for-parents algorithm)
NFC

And RBF is different from CPFP.

Currently all transactions being made on Mycelium don't have an RBF flag. Many users on Reddit suggested this before until now they didn't support the RBF feature.
So there's no way to bump the transaction.

If OP didn't send the whole amount and it still has a small change, he can able to perform CPFP on Mycelium, or if OP sent BTC to a wallet that supports CPFP, he can make another transaction even isn't confirmed yet with high TX fees.

Since OP sent it to Coinbase, what he can only do is to wait since there are some blocks that confirmed with 1 sat/vbyte like 15 hours ago. So I think you don't need to wait for 2 weeks because it might confirm later within a day.

I usually don't recommend sending bitcoin transactions with minimum fee, but these days mempool is fairly empty and transactions get confirmed faster.
If you need faster confirmation you can always check mempool.space website to check the current state of mempool.
You also have to take into account that Coinbase needs additional time to update your account balance.

Do I just have to keep waiting or does that error message from the rebroadcast mean something worse ?

I would just wait, but in future I would switch to better bitcoin wallet, for example Electrum or Sparrow wallet.
