My working theory:
Key = 0x101d83275fb2bc7e0c
Using the
Scooby Doo: Origins method, the key was found after 0.7206% of the range.
That's like, an investment of maybe $ 2000 or less

The Scooby Doo: Origins method proved its worth. I now wonder what the magic method would have accomplished. Maybe it founds the key faster. Who knows? After all, it praises itself as "we save scanning vast amounts of the key space". Well, Scooby Doo: Origins saved 99.28% of this vast space.
Now, how can the Scooby Doo method be put in practice? Oh no, so many cloud services to allow any n00b for scanning Puzzle 69, without having any idea what the software actually does. Sounds like a very good chance to get rich, right? Pay for renting some GPU, give 0 shits on whether it actually gets you anything in return.
