After setting up an encrypted wallet and giving it a QTUM balance, my OS crashed and I lost my last backup of wallet.dat. Is there a way to salvage or otherwise recover the wallet?
I have only the wallet address, passphrase, and blockchain tx data. The balance is in the wallet, but before any further tx I will need to reconstruct the wallet.dat file so I can restore.
Please help. Alternately, please advise me that my failure to keep another backup of wallet.dat is an irreparable blunder.
