yes go to github
https://github.com/iceland2k14/quick download quick or just pubdiv.py instructions on page are very clear how to.
so to reduce 2 you need to generate 2 power 2, 4 keyspaces 2 power 4 etc
Power Value
0 1
1 2
...
50 1,125,899,906,842,624
Going back to this... So you drop it 50 bit... Get your insane number of public keys. Theoretically if you then Kangaroo it and get the private key in the range of 75...What's the following process?
To add to it...
Yes, first you would have to generate 2^75 pubkeys, and then run the kangaroo program, 2^75 times, once for each pubkey generated.
