My transactions and Balance Missing after upgrading my wallet

[manlavan1106]

Hi all,
I am using BITCOIN CORE QT wallet, and used bitcoin core - qt version v0.15.0.1 and my wallet was synchronized till mid Nov, 2017. I had upgraded recently to receive some balance to v0.16.0 version for windows. I had no balance. But there was lot of transactions from last three years.

Unfortunately, i lost all my transactions after upgrading and synchronized till date. I kept my blocks and other folder in external hard disk, each time i want to do synchronization or want to do any transaction, i always copy wallet folders to my system and re copy after my work done.I never had any issue till now. i did one test transaction i didnt receive this balance - 0.0005 BTC). I did not see any transaction out of hundreds of transactions after upgradation and synchronization.


Anybody could help me to retrive my balance and transactions since i used this wallet and ID in many online wallets and exchanges?
Thank you in advance

Have you changed the data directory of the wallet? Your wallet.dat might be incorrect which would explain why the transaction isn't showing.

Go to Help>Debug window>console and key in this

Code:

validateaddress 149HsqLrxn2u55623zs3PsuNz4mo3g6NMn

.

If the ismine returns true, then you don't have to be too afraid.

If your wallet still contains your private keys, you could just run Bitcoin Core wallet with a "-rescan" argument.

i got this ---

"ismine": false,
  "iswatchonly": false,
  "isscript": false,
  "iswitness": false

Have you tried -rescan as aleksej996 said?

Otherwise, it means that the address didn't belongs to the wallet, I think you know this.
The first paragraph from the OP strongly suggests that it is an old backup.
Most likely, you've unintentionally overwritten the most recent wallet.dat by an outdated backup during your copy-paste procedure.

Since your wallet does not contain the private to your address, it probably is not the correct one. Do you still have an intact (and untouched) wallet file (backup?) anywhere?
Or do you only have 1 file which you move around all the time ?

If you can't find the correct .dat because you have overwritten it, you might try using a recovery software to restore it (but make sure to backup all of your relevant files before doing this).

[..] i used this wallet and ID in many online wallets and exchanges

This is an address. And a wallet manages your public-/private- keys and displays your addresses.
Regarding your privacy, it is a bad habit to use the same address on multiple online services/exchanges. You are basically giving away your whole privacy.
A better approach would be to use a new address each time you receive coins to your wallet.

Thank you for your support.

Problem solved.
Rescanning helped

I had all my wallet files back and replaced current files with old back up
then it started rescanning and i got my entire transactions back.

Thank you

I don't make traditional backups of my wallets or the blockchain. I have an version of core that relies on an external hard drive for the information. I have more than 1 external hard drive, and i just connect the appropriate drive and synchronise the blockchain to make my 'backup'. Can anyone see any problems with this alternative method of backing up Bitcoin?

When connecting your second hard drive and syncing the blockchain, do you also perform a manual backup of your wallet file? Syncing the blockchain does download the missing blocks and build the chainstate.
Since you actually have to manually copy it to your second hard drive, it doesn't differ from a traditional backup (or what do you define as a 'traditional' one?).

It has the same effect. I copied the blockchain and wallet from my internal drive on the Windows machine onto an external HDD. That saved me from having to download the blockchain. Now I plug this into the Ubuntu netbook, and run core. As the core on this machine doesn't have a  wallet or blockchain linked to an internal drive, it gives me the choice of previously linked hard drives. Selecting one, and letting core sync the chain doesn't seem to cause any problems, and I believe that this gives me a number of backups without having to copy the full files. Because all transactions are based on the blockchain, I believe that any of these 'backups' will allow me to spend my coins should I widh to do so.

No need to backup the wallet, as core will update this for me. Which reminds me, I need to keep the core versions the same, and I haven't updated the netbook to 0.16.1. I'll update with the SSD drive, and then switch to the HDD and see if it gives me any problems.

Well, it gives you backups of the blockchain and chainstate files.

Because all transactions are based on the blockchain, I believe that any of these 'backups' will allow me to spend my coins should I widh to do so.

These files will NOT allow you to spend your coins. To be able to redeem your UTXO's you need to sign a transaction with the corresponding private key (which is stored inside the wallet.dat).

No need to backup the wallet, as core will update this for me.

Core does not update your wallet. Once you choose a hard drive, it will sync the blockchain and you will be able to access the wallet stored in this directory.
But updates or backups to the wallet file itself are not done.

That's the point though. The entire folder is his "backup".

OP now has Bitcoin Core running on Windows box, fully synced, with a wallet.dat... and a full copy of the Bitcoin Core datadir (including blocks, chainstate and wallet.dat) in his external drive that can be connected to the Ubuntu netbook.

Personally, I think it's slightly overkill to have a full backup of the blockchain... But if you have the storage and bandwidth, why not?

The only issue I can see with this setup... Is the potential for things to go wrong if OP wants to encrypt the wallet.dat and/or changes the wallet passphrase. Doing either of these things can cause problems as then the wallets will be using different seeds/addresses.

OP would need to ensure they then copy the wallet.dat with new passphrase from one system to the other. You cannot simply changing the passphrase on the 2nd wallet.dat as that will create a new seed/addresses for that wallet.dat and there is potential for coin loss.

I think it's possible after you update your upgrade to the latest version you're doing. So causing damage to your wallet. Try going back to your original version.

I think you should read the previous replies, I think, in order to see if the issue was already resolved or not. I think
