Topic: My whole transaction history has disappeared, i cannot access my coins - page 2. (Read 2251 times)

That address is completely empty.
If you didn't make that transaction then it's likely your coins may have been stolen by a virus/Trojan. Unless you used a watch-only wallet.

If you're going to import a private key with a high amount on it at least run it on a live CD or safe mode to limit virus activity.

Unless: you sent the coins to another wallet instead of that one.

I cant understand how my casascius bar could still have btc in it 

If you click on one of those transactions where i transact out of the casascius address, thats a 2015 transaction. Further from that you can find transactions on 2016 

And thats where i found the 3K address.

I mean i didnt send anything in 2016, i only checked my wallet.

Whats going on?

You're cascius coin still has bitcoins in it so if you have the private key for that you can get that money back.

As for the 3K address where is that from? What does it say in your electrum wallet window title bar?

Here is the public address for my cascascius bar:

1GCqjEHwr1BUU7wArNF4X5htyTAwR7Ljzc

https://blockchain.info/address/1GCqjEHwr1BUU7wArNF4X5htyTAwR7Ljzc

So as you can see, i loaded it in 2014 and then moved it to my electrum in 2015 (somehow it shows that balance is still 1.6??? must be a mistake). Now clicking on those addresses i didnt notice the 0.6 i transferred out, but it seems that in 2016 all the addresses seem to have transactions out, at exactly 2016.02.22

Am i missing something? I think that could well have been the day i last checked (apparently a bit more than 1.5 years then) and saw my coins there. Did i get hacked or am i missing something???

When doing this, be sure to back up the entire electrum data folder and the wallet files inside it. Just in case there's another issue and you need to gain access to them at a later point (once the new wallet is fully functioning though, it is acceptable to delete those backups if needed).

Maybe your electrum is corrupted that is why its sometimes not asking for the seed/password or maybe your internet is slow do you have any stable internet? Also did you install carefully the latest version if you install the electrum without removing the old one or uninstall you can experience of some conflict base on what i experience before so much better to remove the old 1 an re install the new version of electrum..

It will only ask for the password to open the file if the file has been encrypted... which was a relatively "new" feature... so an older file probably wouldn't be encrypted (only the seed/private keys inside it). So, an older file would only ask for password when doing tasks involving private keys or viewing the seed etc)

It boots, but sometimes it fails to start and there is nothing else i can do but shut it down from the power button. Thats why i dont like starting it up in the first place. It no longer starts electrum, and when i tried starting it from the terminal it complained something about the config. file getting an error.

Wait, should it ask for my password when i open the file itself, or only when i ask for the seed/perform operations? It doesent ask the password for opening it.


Ok im gonna do this, i think i still should have both the casc private and public key stored.

Why don't you look up the cascius coins' address on a block explorer site and see whether it still has funds in it or not? See if those addresses are in your USB wallet.

If all the money has been sent from the address then see if the destination address is in your electrum wallet (this would be a private key sweeping transaction).

Block explorer would be a site like blockchain.info

Finally there is one last thing you can try but you have to do this offline. Open the site bitaddress.org and disconnect from the net. Go to wallet details tab and enter your cascius coin private key(s) there. For each private key you should get two addresses one for the compressed public key and one for uncompressed public key. Save those addresses in a text file for future reference. See if any of those addresses are in your electrum wallet.

Before going online again close the bitaddress.org tab and then your browser. You can run your browser once you've gone online again.

Alternatively you can do all of the above using a live cd. Bitaddress.org is just one self-contained file and can be saved on a disk for offline usage.

Yes, it should... but can you be certain that it IS the original wallet file? 2.5 years is a long time ago... and there is no real way for us to know exactly what you backed up to USB. I still think it might be more likely that you've backed up the wrong file and the wrong seed, it's the only explanation for the fact that your seed is generating addresses that have no coins (and your original wallet file gives you that same seed)...

I'm fairly sure that if you opened the true old file with your coins in it, in a new version of Electrum, that your coins would be available. The only way for this not to happen is if your file was either corrupt (but Electrum should detect this and tell you) or you are opening a file that is not the one with your coins in it.

At the end of the day, I guess it doesn't really matter... either way your coins seem to be gone

Do you still have the original Tails OS on the USB? Does it boot at all?

What is that link?



For me this has for sure become a permanent red flag on electrum. My mistake, someone elses mistake, whatever it is: i was under the impression my coins were safe. I cannot trust electrum after this. In fact, i dont know what i can trust anymore. Cant trust myself either, obviously.


I have the original wallet file that im holding. I have both the seed and the original wallet file. Shouldnt the original wallet file still do its thing?

Did my wallet file just decide to fuck itself up one day and throw the private keys in the trash can?

Shouldnt the original wallet file still contain the private keys?

The seed version should not make any difference... Electrum detects "old" seeds and will recreate the old wallet correctly. I've just tested with Electrum 1.8.1 and 1.9.8... Seeds generated with both of those versions will restore into Electrum 2.9.3 just fine. They show up as "Seed Type: old" when you type them in, but 2.9.3 will still generate exactly the same addresses as the earlier versions using the same seed.



Based on this little snippet of information... Perhaps it is possible that the OP has created a wallet in Electrum, written down the seed... and then imported the private key (older versions allowed "hybrid" wallets that contained both seed AND private keys) and possibly missed this warning:


Wallet has then been recovered from seed at some point... and the private key containing the coins has been lost

Don't want to thread jack but I feel this sounds like a problem I am having at the moment as well.

I installed Electrum 2 nights ago from a link (Version 2.1), created a new wallet, saved the seed address. Used my receive address in my mining .bat file and started mining. The next day I noticed Electrum wasn't connected. No matter what I did it wouldn't (only listing one server).

I reinstalled Electrum from the actual electrum website on my main laptop. This was the latest version and it connects to servers now. I copied my wallet from the mining rig, there was only one wallet called default_wallet.
What was strange was the file opened without asking for my password or anything. None of the address matched and my old address wasn't listed under changed. I then tried to open it from the Seed address I saved the night before. Same issue/address all with no history. Although i may not have any history or funds yet I would still like to see my address from the night before to make sure.

What is odd is none of the new addresses will work with the miner. As soon as I change the .bat back to the old address it starts working again. So I cant even start again with one of these new addresses and I cant access my old one.

Possibly the same issue as OP which is why I thought Id mention it here rather then a new thread...

The master public key you sent me has NO HISTORY AT ALL.
This means, your seed is wrong or there's an issue with the formats changing between the new versions and old versions of the electrum client.

The seed format has changed since the first wallet realease, I'd suggest you try this with your seed just to check it. This one supported MPK keys and is the latest one I can find that does (though I didn't do too much of a search, though my seed was generated from 2.6.3).

I received enough information via PM. Will load it into a watch-only wallet once my computer loads and check the addresses.

No, i sent coins to wallet A from a paper wallet and the password i have of wallet A corresponds to the seed which i have on paper when i open the file and ask for the seed. Ive used the same wallet to send coins.


485084 at this moment.

Tried multiple servers.

I also have no issue importing other wallets successfully.


crtl+a does not seem to do anything, but from view>show addresses i get a bunch of empty addresses.

I dont remember how i did it exactly, but i had like a casascius cold wallet, and i got its private key into my electrum with someones instructions somehow. I honestly dont remember, but ive used electrum to send bitcoins after that from the same wallet.

I said private key not public key. Any one private key + the MPK = whole wallet compromized. There is no reason to believe any of the OP's private keys have been exposed. Just saying that exposing the MPK is not entirely risk free.


No that's not the case. Electrum maintains backward compatibility with old seed formats. The MPK would be of the old type too.

@Numerous64: You haven't answered the question HCP posed about familiar addresses. Can you bring the address tab into view with ctrl+a and see if any familiar addresses are listed there?

Also please answer the question I posed above regarding sweeping vs. importing.

I'm not particularly sure any of his public keys would be exposed. However @op if you have a problem with this, you can PM me or the user I just quoted with the public key.
Also, if the seed formats are the same and a new wallet is created then an xpub key should be created shouldn't it? Otherwise, the problem op is facing is merely a compatibility issue.

Did you sweep private keys or import them? I don't think the option to sweep private keys was there 2 and half years ago.

If you imported them then a restoration from seed would not restore the imported private keys.



For a 2.5 year old wallet it'll be the old style hexadecimal MPK rather than a bip32 xpub. It's worth a try though. We can create a watch-only wallet and see if there are any transactions.

Ah your wrong about the privacy leak though. The MPK is normally not revealed to electrum servers so exposing it is a big privacy leak. It also has security implications. If any of his private keys were to leak too then his entire wallet could be compromized.

@OP, if youre sure the seed is correct and what HCP suggests isn't working. Can you go to wallet>master public key from the top menu and copy and paste the key beginning with "xpub" here.
There isn't anything anyone can get with that key other than information about your wallet that is public to nodes already.
