I have created test coins and mined genesis blocks learning how everything works
... mining a genesis block can take up to an hour (or more) depending on hardware.
You would need to be trying to hash the genesis block on a Tandy from the '80s for it to take longer than an hour (assuming you are doing it the correct way)
Ahh... ya got me... I did engineer it into 6809E (Yes, E) code and tried running it on a color computer 3!
Lol... Like I said.. I was learning -- not implying I knew fully what I was doing.
