I wrote a small python script to try to predict the next number of the #66 address
useless - you cannot predict the privkey of
any puzzle address
quite right as any of other methods... i'm trying a new approach now but it will for sure fail or for the fun of things maybe not.
i'm trying random vs random but on smaller scale (like 16^9), chance 1 in 200 for each run on my current setup.
in testing i have got better results starting with sha256 hashes of random "strings" instead of simple RNG or sequential but still didnt found anything.
Good luck everyone...it's all about luck... as for now SHA family is safe
