My computer has been searching for about a year, and I'm not hopeful.

However, today it occurred to me that the transfer of the person who finds the 64th puzzle may be cancelled.

In other words, after the transfer process starts, the public key will be revealed and thieves who do not deserve it will find the public key within minutes with Kangoroo. Then they will open a double trade with RBF by spending high, the transfer of the person who finds it will be cancelled.

It occurred to me that the thief would figure it out in about 3 minutes.

The average bitcoin transfer confirmation takes 10 minutes and can be canceled without 3 confirmations. (I could be wrong, please correct me.)

How can you get 3 confirmations in 5 minutes in Bitcoin transfer?

First, you have to know that finding a private key with Kangaroo in range 8000000000000000 to FFFFFFFFFFFFFFFF takes less than 10 seconds with a gpu like RTX 2080ti as I tested.
Replacing a tx in such a situation was also a question for me:

Yes, I'm sure they'll find it in such a short time. They can create RBF in 1 minute in total. Do you have an idea as a solution to this?
