I am the creator. No,, not god man. I am the creator of this puzzle! I apologize, I had a bug in my script that generates WIF and ADDRESS so I was 100% sure it was using a 66 bits key but in fact it was using 62

. Well the money is still with me, so bug have been fixed, we will try again Tomorrow
I don't know what are you trying to prove, you don't need to do it. In any case you can generate address in any range with my tool
