On May 27 I tried to sell some Bitcoins(for the first time). Since that day the transaction is in the status "unconfirmed". The amount is booked from my wallet, but isn't booked to my bank account.
The solution I found to solve my problem was to start the Bitcoin core wallet with "
-zapwallettxes". I'm using Win10 and don't find a way to do this.
Has anyone got any idea on what can I do to sell or to get back the Bitcoin? Answers in German are welcome too.
