Wallet suddenly empty

[Prutser112]

Hello Knightdk,

There is nowhere the file 'blocks' on my desktop? continue anyway?

That is a problem, but sure, continue anyways. Did you happen to delete anything between the time when this problem happened and now?

I started the program after following instructions.

Now the program started with "synchronizing with network"
That means it has to download again the whole amount of GB's of data like the prog done it before?

B.t.w. this time I got a question when starting Bitcoin Core, It asked if I wanted to store on Desktop or custom location, Application Support.
I have chosen Application Support.

Yes, it will be downloading the blocks. And that is good keeping it Application Support.


Btw, keep your backups.

This program Bitcoin Core is not for faint-hearted...

Of coarse I keep backups!

Now see how long it will take to pull in the whole Block chain.

Should I keep all debug files, etc that are still on Desktop?
After removing Bitstamp, it's files stayed also on my desktop... I don't know which ones belong to Bitcoin Core and/or to Bitstamp?

That is correct. Because the "blocks" folder was missing, it needs to redownload the entire blockchain since that is stored in the "blocks" folder.

No, you don't have to. All of the files I told you to copy earlier can be deleted from the desktop.

Thanks for the assistance so far.
I will inform when blockchain is in.

Is it normal that my Mac nearly overheats from downloading this Blockchain?
The fan is meanwhile blowing full speed and still I can nearly bake an egg on the alu housing...

Bitcoin Core is pretty hardware intensive, especially when it has to index the blocks (as with downloading or reindexing). I wouldn't say that this is normal per se, but it certainly is not uncommon nor unexpected.

It will get quite warm verifying all the blocks, yes. 

Which Mac are you running, out of curiosity?

That will definitely handle it, it will get warm though while doing the initial sync.

Hello Knightdk,

After two day's the blockchain still is not fully loaded.
This morning the macbook reported me that Bitcoin Core program was terminated cause of "no more free memory" with a red stop sign.

I have 250 GB SSD, little to no programs on system, little amount of pictures, no video's, but still it say's that all my memory is used.

The block chain still to be pulled in, is of last 6 days.

Now trying to make space.

Hello Knightdk,

The wallet is now synchronized and ready, the amount of Bitcoins in the wallet is still 0,0000000000
So empty...

How can I get my Bitcoins back?

I am getting even more nervous now...

Hi,
If the message really is "no more free memory" that should be referring to memory, e.g. RAM, not disk space.  However with 8GB of RAM, you should not be running out of memory.  Was that the exact message?

And, how much free disk space do you have?  (That was one reason I asked earlier if you had an external hard disk drive attached because it was possible that you had done so in order to hold the block chain and avoid running out of disk space).

It is possible that since the program quit because you had no more free memory that it isn't current and you might need to do a rescan.

One suggestion for you to consider would be to dump the private keys from your wallet.dat files and then find the address that had your balance and use a different lightweight wallet (e.g. one that doesn't need the entire block chain). This would avoid all the delays doing a rescan or re-downloading the block chain.

Hello CR1776,

It was not a message about memory/RAM, it was about free disk space. (my wrong description)
The exact message I don't have anymore cause it disappeared quickly, only a pop up message from the mac.

Now I have been deleting 'useless' things and empty garbage, 90 GB free.
So that should do.
I did not store the chain on another/external HDD cause I thought I had space enough.

The program Bitcoin Core is now ready, while starting the prog, it said re-scanning and showing a progress in percentages.
After starting full, the page say's still 0,000000000 BTC, no transactions, nothing.

I have just asked/contacted the seller of my Bitcoins for help.
The wallet.dat file will be mailed to them in a secure way and they will try to regain control over the Bitcoins.

If you haven't sent the wallet.dat file yet... DON'T!!!

You should NEVER send your wallet.dat file to anyone, ever... That is literally like handing over a physical wallet full of money to someone. Unless that person is completely, 100% trusted then this is a VERY bad idea.

I hope you have not sent it yet... if you have, and the person you sent it to is not a close personal friend of yours and/or 100% fully trusted by you, you may as well kiss your bitcoins goodbye!

Take one of your backups and put it in the data directory. Make sure that you replace the walet.dat file that is already there. You should also check the creation dates of the wallet.dat files (I don't know how to do this on a Mac). The file with the oldest creation date (note, Creation, not Modified) is most likely to be your wallet.

Also, it would probably be a good idea for us to see the debug.log file again.

You data directory is /Users/test/Library/Application Support/Bitcoin. This is where everything should be. Put a backup of your wallet.dat in that folder.

If your wallet is encrypted, the one that Bitcoin Core is using is not encrypted.

Hello Knightdk,

After restarting Bitcoin Core (when the Chain was fully in this morning) there was only one file in that directory "Bitcoin", called "wallet.dat"
I have no clue where all other files are that were made, no "log file", no "peers", no file nothing.


With that newly created "wallet.dat" file, the wallet of coarse showed 0,0000000 btc.

I replaced that file with the old file "wallet.dat" and the wallet still shows 0.00000000 btc.

I am lost.

Did you happen to download an infected copy of bitcoin-core? Specifically, check the PGP key of the downloaded file?
 I have not come across one yet but it is certainly possible that some no good fraudster is using a modified bitcoin-core executable and stealing people's money.
