But if I had the private key of someone's address and I wanted to steal the fund, I would make a non-RBF transaction.
Haha 😂 that’s why we are always hoping that scammers do not have this tech knowledge equivalent to people like you.
But if you make non-RBF transaction can’t it still be replaced if the server or node is full RBF opt in? Or is there way to know maybe a node isn’t full RBF so one can change server when looking to make a non-RBF transaction
