Thanks for replyin and for the link.
It seems I hav two options....one to wait and not open th wallet till transaction is dropped (no certain time) and second the below
"Bitcoin Core makes making Full RBF transactions very easy. Simply go to the transactions list, right click the transaction that is stuck, and choose the "Abandon Transaction" option.
If that option is greyed out, then you must restart Bitcoin Core with the -walletbroadcast=0 option and then you should be able to use "Abandon Transaction".
If the above two options fail for some reason, then you can start Bitcoin Core with the -zapwallettxes option to clear all unconfirmed transactions from your wallet.
Once the transaction is either Abandoned or cleared from the wallet, you can simply go to the Send tab and send the Bitcoin again but make sure that you include a sufficient transaction fee."
I hav been waitin for 7 days now so want to try second option. However, if I do that will my BTC be safe? Its a big amount for me (0.48 BTC)
Plus how to do it, "to start the Bitcoin Core wallet with -walletbroadcast=0 option"? I just double click th wallet and it opens and starts to sync automatically...
Thanks again
