Maybe disabling RBF would be a start, and using a high fee.
Yep, that's the solution. It is one-time try only.
This has been bugging me and put me off from searching 66.
Ok so say i found it can i make the fee high enough like in electrum and broadcast it a few minutes before the next block ?
This way i have a few mins to get in next block before the pub key is cracked.
Otherwise what is the point ?
