Bitcoin Forum

I wanted to ask this question yesterday, but was busy. I know that once a wallet finishes synchronizing with the Blockchain, it's supposed to display all funds related to that a particular key(seed). However, I recently encountered a different issue. My old wallet, which I used for signature campaigns, was created using Mycelium. Mycelium creates an HD wallet. It hadn't given me any issues until last week when I tried to move the piled up coins to my other wallet. Due to the high cost of fees, I had to wait a bit, which I did. Yesterday, when I was about to move the coins, I noticed that the mempool fee was different from that of Mycelium. Mycelium doesn't give the option to adjust fee. So, I decided to import the seed into my Blue wallet.

To my surprise, the total sum of coins I found on Blue wallet was different from that on Mycelium, with about $70 short. I didn't understand what happened, so I cleared the app and reimported the seed again. It finished synchronizing and showed the same balance. so I thought for a while and used my mobile Electrum to import the same seed. But Electrum, after synchronizing, displayed the same balance as that of Blue wallet. So, I couldn't really understand what was happening.

my question here,  is it possible for different wallet apps to display different balances? I know I've seen this question before on some other thread but can't seem to find it. Also, on  HD wallets, how do I know the parent address? Is it the first address created by the wallet? Because if I could have just used the parent address to check for the total balance using Blockchain explorers, but I couldn't find it. Though I had to move the coins using Mycelium at the end and created a new wallet, I want to understand what happened. Could someone explain?

This is a bit awkward because the difference is too large, the only times this difference occurs is when you import address and maybe forget an address like the change address and there is a balance there. Or maybe the mycelium wallet hasn’t synced properly and might still be using the old bitcoin to dollar price, you know the price is falling.

My thinking is that maybe the aggregator for bitcoin to $ for the wallets are different but still $70 is a huge difference. So maybe you should rather check the bitcoin quantity instead of its conversion price to dollar and possibly check whether mycelium actually synced.




All addresses are the parent addresses, when you create an HD wallet on wallets like electrum then it gives you 20 addresses to recieve bitcoin so it depends on which one you have used.

What you should do is if you have used just one address from that wallet then go through the addresses on received address and the one with only balance showing is the address.

Mind you, you can’t get the result of the total balance by checking using explorer because the wallet might have coins on change addresses too

Can you ensure that your Mycelium wallet has no unconfirmed TXs or is fully synced to show the right balance? That's the possible logical explanation for why you see a difference when you import the seed into electrum or any other wallet.

Another possibility is when you use a different derivation path from the actual one but it will give zero balance instead of any.

I have also experienced a similar issue once sometime ago. There are two possible problems that may have resulted to this issue. Firstly did you check is you had any spent utxo that hadn't been confirmed? This is because sometimes these wallets subtract spent Transaction from your total balance of the HD wallet even if it hasn't been confirmed yet.

Another thing to check for is if after you had imported the seed to another wallet, if all addresses including the change addresses were imported. However most times ,once your wallet has attained total synchronization, they are supposed to appear. Therefore the main reason your balance could be reduced is if a spent Transaction was subtracted.

I really don't think that's was the problem. All my unspent balance were confirmed. And when I had finally initiated the transaction using Mycelium, it displayed my total input and output on electrum and Mycelium where I had imported. I just think that Mycelium has some bugs or issues with synchronization. As I've seen some other people complain about similar issues before.

Right, but it sounds like more of a "cache" or "display" issue than synchronization since it used the correct inputs to your transaction rather than the set with $70 more amount.
Because otherwise, it should've added an extra input(s) containing those $70 worth of Bitcoins that are already spent.
Anyways, reloading the account to trigger a rescan is useful in cases like this.

Yes it is a synchronization issue and the last time I read about it was that the Tor network in the wallet setting was. Automatically turned on and since you don’t have an Orbit the wallet would have a Synchronization problem. So why don’t you locate the Tor network in the wallet setting and then turn it off to see maybe it could be the same issue you are having

Update the app to the latest version, and if you have more than one account, Account#1 2 3 4 5, make sure that they are all synchronized.
Check the balances in Electrum > show addresses and then compare the addresses with their balance in Mycelium.
If the problem is not resolved, copy the about > logs and paste it here.

It only allows you to use Child Pay For Parents CPFP, not Replace-by-Fee (RBF).

It can be different when you connect to different servers and to mempools which have your pending transactions or don't have it.
