Now all brute force method bitcrack, kangaroo, BSGS all stuck with high rank of very very large keyspace

if scan all it use a time too much

We need to find the way and method to can calculate or guest right keyspace 
may be an help reduce from 1000 area to scan 100 area

use pubkey to caclulare direction of keyspace  and then use  bitcrack, kangaroo, BSGS

if can fine keyspace  low than 2^30 to 2^40 may be better ot less 1 days scan complate (Max 2^50)

(2^ 60 too high)

other puzzle no pubkey  still no idea what to do?

Anyone have any idea use pubkey to calculate keyspace  ?

To do brute force all area of keyspace in range it is not good idea?



Anyone an expert with python language please advice. Can you do Ai. on python?

I think about used version python scripts with all AI. api
it can possible to generate private key with address to as dataset and train Ai.
and do brute force by random with use call AI. model to give multiply value. something like that
just learn to read a lot about AI. deep learning.
