Hi, thanks for the suggestion.

I am certain I have not gotten the wallet from a third party, nor have I edited anything in it. The wallet is not encrypted, I have extracted the private key and imported it into Electrum in my trials to try to get this to work (with no luck).
Electrum shows the history as being empty, with no currency in the address.

Can it be that the transaction was simply rejected + forgotten, voiding it and its related ID's? Speaking of bad luck.

I am definitely going to do that, would that really be it?!
I have checked my address online and it also shows 0 BTC balance. Sorry if this is a stupid question, but isn't this kind of stuff decentralised and thus not dependent on one wallet syncing?

Hello all,

With all the Bitcoin news going around these days I decided to check my pc for 'that old wallet' I was sure to have laying around somewhere from fooling around with mining BTC a few years ago. Lo and behold I found it, and it has caused me a big headache in trying to figure out what's going on here...

When opening the wallet.dat file I found a ~600BTC (inbound?) unconfirmed transaction to (my address? https://blockchain.info/address/13TprxCKbWe2i1QrmtEHeRYafbjicL2ivG) which has apparently been that way since 2014.

Can anyone please tell me what this means, if there is any way I can get to these bitcoins, and how I am supposed to go about doing this?

The transaction has the following properties:

Trying to resubmit the hex to the magic bitcoin pool of processing things by putting it in here https://live.blockcypher.com/btc/pushtx/ it comes back with the following:

"Error validating transaction: Transaction c66189403a951eeea37f59b875947ff77a220b560821d5cc31bee1801255262a orphaned, missing reference 1c7a50c64aa095523e4dc9bc23e7a1c8b0b92f3523b645eb643169f45cce0167."
