Sorry guys & gals - yet another "unconfirmed BTC transaction..".
Looks like the fee was too small, but this was sent 72 hours ago now (at the time of writing)

Do I just need to be more patient?
Edit:12/06/16 - It has been over 120 hours now, are there any options for me to retract the transfer and re-submit with a higher fee?
