you too busy to judge my opinion bro, look at the WORKING TIME it's say 00:00:00s, i run this command took 5 second to DONE. you know i mean right ?
so why you just think it's so instant ? if this so fast? why you need to run the command manualy, so ?  
Kangaroo 1 second ?


Here's the right RANGE if you mention me about the wrong range.
i have more range nonce about the pubkey 65.

Results,

I never found the BSGS-CUDA running on linux/debian, still use the Windows version, There's the github you can download the BSGS-CUDA windows and already compiled.
you just need extract the zip, and put the exe on the same file.

test your luck here, it's safe no random malware.

[EDIT]


I try to scan the #65 Puzzle with BSGS-CUDA, using GTX1650Ti [Testing the 30 # puzzle]

only 5 seconds.

IMO imagine the puzzle maker show pubkey the #66 Puzzle, maybe it's take the same time like 10-20 seconds haha.

for me, it's faster BSGS CUDA

maybe it's arround hundread mkeys no ones tell about the speed of 3090, but i have a proof about my GPU 1650Ti running BSGS-CUDA

This.

I scan and i got 380-370 Mkeys average

maybe you can check this youtube video, he's trying Kangaro with 8x RTX 3090 on Vast.ai

I know right, still same, we need the public key, because no public keys mean more time.

I knew because it's difficult by times to search too, there's no magic tools to solve the puzzle by day,month, years for possible.
last time i scan the 125# puzzle with my 1650Ti, it takes like 800-900 years, im new in this puzzle and learn from people who's tryin to figure the pattern to breach the puzzle.

FUN FACT is you need like 1000-2000 GPU units for breach the #66 with kangaroo, to short the time like 1-2 years.

regards,

So the point is we cannot do anything to solve the 66, because we need public key, we cannot seek the public key because the address never spent any ammount thoo 

I do RMD, and PUBRMD, for like 1 years and nothing to found.



#120 never given the hex key too
