bitcoin core wallet shows empty balance and no transactions after "-zapwallettxes"
i think i have done a big mistake.
I tried to transfer BTC from my bitcoin core to bitfinex with minimum transaction fee.
After 2 days it stil shows unconfirmed. I googled for "delete unconfirmed transactions bitcoin core" and found this link:
https://www.reddit.com/r/Bitcoin/comments/59h8f4/how_to_delete_unconfirmed_transactions_on_bitcoin/i didnt read the whole thread and so i started my bitcoin core (v15.0) with "-zapwallettxes -rescan"
After that i read next line in thread and found "-rescan is not necessary". Then i stopped the just starting bitcoin core wallet and started again with -zapwallettxes but without -rescan.
after that it shows empty balance and it shows no transactions.
My last backup of my wallet is 3 month old and after that i recived some of BTC transactions.
Now (after my mess) i exported my wallet and the DAT-file is 1MB size so i think there must be something inside? My wallet has a passphrase and bitcoin core also shows.
Now i stopped my bitcoin core and i am waiting hopefully for some instructions.
