I have been experimenting for months with popular algorithms like Kangaroo, Baybestep,.. but all have no results, need more efficient algorithms. As the last comment of author Satoshi_Rising he said all addresses belong to the same wallet, this means they have the same master key. Hope some genius will have more ideas.
 

basically we should try a different approach. I am starting with the idea of ​​converting the private keys to binary, as per the author's comment. It is easy to see that the keys all start with 101,100,110,111 and the substrings inside are 00, 11, 000, 111, 0000,11111,... we can reduce the search space quite a bit here, we can use more markov chains to generate high probability strings first. Generating keys and applying keyhunt will help speed things up a lot.
