Guys I have three questions:

- 2rd question:
I did other tests on other puzzles but I saw that on puzzle 33: https://privatekeyfinder.io/bitcoin-puzzle/random-keys/33
Onwards, BitCrack ends and does not generate any key.txt
I did the test again on the initial puzzles that worked to see if it was an error on my PC but it ended up generating it normally, I went back to puzzle 33 to see if it still did not generate anything and it did not generate anything
Why does it not generate anything? It is frustrating to leave the PC running the Unsolved puzzles without knowing why it ends and does not generate any key.txt
Oh, I did a calculation so my monkey brain could get a sense of speed and know the proportion of MKey/s in time.
I saw that in Unsolved Puzzle #66: https://privatekeyfinder.io/bitcoin-puzzle/random-keys/66
For example, the range is from 40000000000000000 to 7ffffffffffffffff
So there are 4,611,686,018,427,387,904 keys in this range
So in one of the worst cases, a person who has 2.48 MKey/s, would take 58,926 years to process all Keys
In one of the best cases, a person who has a GeForce RTX 3080 with 1211 MKey would take 120 yearsThen I thought, why don't these AI servers with thousands of GPUs just solve all these puzzles?
