thank you. this feature is really fucked up .
like there is no max or smth. or a security. they should have integrated, that coins are locked in some way as long as the transaction is ongoing and that you can not change the destination address.
you come to this conclusion solely from the perspective of your current glasses in the position of puzzle hunter #66. otherwise, RBF and similar techniques have their reason of existence and this was also agreed with the developers and thus implemented. But that would be totally off-topic now, if you want to read more about it, you will find plenty of information in the corresponding sections here in the forum.
I agree with you that this is a pretty stupid circumstance. This is also due to the fact that we now have tools like BSGS and Kangaroo that can calculate the private key very quickly if the public key and the corresponding range are known. Unfortunately, this is suboptimal for us puzzle hunters
