Hi
I don't know if you can move your thread yourself but the forum for technical help is there:
https://bitcointalk.org/index.php?board=4.012 words phrase is likely a BIP39 or Electrum mnemonic, try using tools on internet but use them OFFLINE! I just found this for example
https://iancoleman.io/bip39/The 80MB wallet may be a Truecrypt/Veracrypt container?
Your 'xc2.....2om' word may be a password? Of the container? Or a BIP38 password for your keys?
Thank you for your reply, I've no idea what Truecrypt/Veracrypt container is lol, so I doubt that it's that. Furthermore, I don't really understand what this tool you've attached does. I'd really appreciate if you could elaborate.
In this tool you put your 12 words in "BIP39 Mnemonic"
This will give you a private key in "BIP32 Root Key"
You may need to put your "xc2" password in "BIP39 Passphrase (optional)" too
If it works you can import the "BIP32 Root Key" in Ethereum (I'm not sure bitcoin-core has implemented BIP32 yet) and use your funds
