Then the other explanation might be the "gap limit" of Electrum... and your coins are "hiding" in an address that Electrum is not "seeing" because it only generates up to 25 "empty" addresses and then stops looking. You can read about the "gap limit" here: https://electrum.readthedocs.io/en/latest/faq.html#gap-limit

To generate more addresses you can use the command on the Electrum "console" (you might need to use "View -> Show Console" to see the console tab):

Every time you type that, it will generate 50 more addresses... you can change 50 to whatever number you like, but you probably don't need to generate more than a few hundred to be relatively sure that the "missing" funds are not hiding past the gap limit.

to be 100% sure you should also try:
which will generate 50 extra "change" addresses so that Electrum can check those too.


Simply go to a blockexplorer like one of the following:
https://btc.com/
https://blockchair.com/bitcoin/
https://live.blockcypher.com/btc/
https://www.blockchain.com/btc/
https://blockstream.info/

and enter your address(es)... see what the "current balance" displayed for the addresses is... if it adds up to the amount shown by Electrum, then Electrum is probably not missing anything due to the gap limit... and the "big balance" you're seeing is just because things were not syncing properly when you used the "Fast sync".


No... he means "denomination"... Electrum defaults to using mBTC (or milli BTC)... you need to use "Tools -> Preferences" menu... look on the "General" tab and see what the value for "Base Unit" is.

It's possible there might be some confusion between mBTC and BTC (or vice versa)... but mBTC should be showing as 1000 greater... not 100 less

ie. 0.38 BTC == 380 mBTC ... and 0.3 mBTC = 0.00038 BTC

Hello,

Thank you @ranochigo, @NotATether, @HCP for your answers.
I am gonna try to reply as much concise I can.


Yes it's what I did with electrum wallet, and the balance is divided by 100. If I don't select these options, I have nothing. I don't have password keys they are encrypted in aes file.

I want to specify, I didn't make any transaction with electrum wallet. With BRD in fast sync, I couldn't.


Yes, it's what BRD support think. There is an issue with fast sync mode. May be the initial balance is wrong ?
I must admit that I would prefer to access to the balance: 0.38 than 0.004. I almost 90% sure it's the correct balance, the balance when the multibit crashed. 0.004 doesn't make sense for me.


No, I forgot this wallet for a long time. No transaction since 2017. Or you think something else ?


Great suggestion. How do you do that?
I would like to check this before let the BRD synchronize completely.


"denomination" ? You mean bip39 => m/0 ? Yes, it's what I did. In fact, I wanted to try your method with password keys imported, and adjust fees before sweeping following this post https://bitcointalksearch.org/topic/--5311792. But unfortunately, I don't have access to password keys because of encryption.

With seeds in electrum, I cannot adjust fees during the recovery process. Is this normal ?


So every advices are precious.

Thank you for your help 

How exactly did you recreate the wallet in Electrum?

Did you select "I already have a seed -> Options (BIP39 seed) -> entered the 12 word recovery words -> set derivation path to m/0'" ?   Or did you do something else and just imported addresses/one or more private keys?

If you used the 12 words, then chances are that Electrum is giving you the correct balance (Especially if you can see some transaction history shown)... if you use individual addresses/private keys, there is a chance you just missed some keys that have balance.

As for BRD, it seems like there might be an issue with it syncing properly... so it isn't showing the correct transaction history/balance.

That sounds like a transaction has been made that spent exactly 99% of your bitcoins.


BRD wallet's fast sync mode is basically a centralized SPV on BRD's servers so it's also possible that the balance reported by BRD wallet may be completely wrong (when in doubt, check your address balance in a block explorer).

A wallet's fee rate does not affect how much bitcoin you see in addresses of two different wallet software.


You should do this. This will synchronize with regular SPV servers and they should report the correct amounts. It shouldn't take very long either, at most several seconds or possibly a couple of minutes.

Exactly 100 times less? Did you check the denomination used in Electrum?

No. The most that could happen is that the transaction gets stuck and/or the transaction cannot get broadcasted.
Did you use the seed and import into Electrum?

Hi,

A few days ago I could reactivate an old multibit HD wallet (crashed in 2017) on BRD, using password seeds. The balance of BTC is similar in my memory and I could extract all transactions between 2016 and 2017 to verify the balance.

Here is my issue: I have the right balance on BRD(Fast Sync mode) but I cannot transfer it neither exchange it. In Electrum, the balance is completely different (around 100 times less).

When I try to sync BRD with normal sync, arrived around 32% of sync, my balance is divided by 100 like on electrum. I stopped the normal sync on BRD. I reinstalled the BRD wallet and in fast sync, my initial balance reappeared.

Here are my questions:

   •   Why the balance is different between BRD fast sync and electrum ? (I read somewhere that multibit HD had very low low fees )
   •   Is there any risk to loose BTC during sweeping process because of these multibit low fees?
   •   Do I have to adjust fees in BRD or electrum to preserve my balance ?

BRD team answer:

   •   They don't understand why I cannot transfer the BTC
   •   They advice me "normal sync mode" and to wait until final synchronisation, according to them, I have no risk to loose my initial balance (because of fees) during sweeping process.

I am little bit lost. To adjust fees in electrum, it seems i need password keys but they are encrypted in aes.
Every advices are welcome
