I've just looked back at your previous posts and found out that you have your own code that you are not willing to share ...
I was just wondering if it can be done with this code ? :
https://gist.github.com/jhoenicke/2e39b3c6c49b1d7b216b8626197e4b89

I tried this

#define GSTEP (1<<28)
#define NUMPUBKEYS 1
unsigned char rawpubkeys[NUMPUBKEYS][33] = {
    {
0x02,0x30,0x21,0x0c,0x23,0xb1,0xa0,0x47,0xbc,0x9b,0xdb,0xb1,0x34,0x48,0xe6,0x7d,0xed,0xdc,0x10,0x89,0x46,0xde,0x6d,0xe6,0x39,0xbc,0xc7,0x5d,0x47,0xc0,0x21,0x6b,0x1b
    } /* 65 */
   };

And got this
Found private key  1:  28e6c7bff92dbd1 or  28e6c7c006d242f
obviously wrong

Thanks
How long did it take and how much mem does it require ...
 
#define GSTEP (1<<29)

is enough or more is needed?

By the way, and you know why their puzzle addresses were removed from the 161st?
My thought is that this is the limit of public addresses. That is the further search in the theory goes on a circle.

            the most interesting thing is that the cache is not touched ,which means that it is not found the key ,and the owner came and took it.  https://www.blockchain.com/ru/bch/address/18ZMbwUFLMHoZBbfpCjUJQTCMCbktshgpe

PoB (Paradox of Birthdays)
PoB as an average prvkey distribution (if believe the statistics), the next time (#62) it should not work.
That is, if #61 it was necessary to search in 30% already win, then now the opposite is true - in 60% never win.
And big problem is that it is not stable.
If you were waiting for the moment know it(#61) was
PoB as recurring characters more stable, it + ~50%.

But, see simple calculation
#55 had a ~50% profitability (use VanityGen) compared to the complexity of mining (end 2018, excluding electricity costs).
(if the seeker is unlucky, and he goes through the whole range and finds the key at the end - he will still receive ~50% of the profit, compared to the mining)
#58 had a ~50% profitability (use BitCrack) compared to the complexity of mining.
#59 had a ~50% profitability (use BitCrack) compared to the complexity of mining only if seeker is lucky and 0% if unlucky.
Suppose that BitCrack can work another 2x faster (in theoretically limit), according to information from this and other topics.
Than #60 - last puzzle, where profit was possible (in theory).
Conclusion - the puzzle is no longer profitable! (only if the author increases the award or mining will not be profitable by 4x+more)
Solve the puzzles for fame? Ok, why not?..
But having opened the blockchain, I don’t see any glory from #58, except for the simple draining of the address

They will not go for it. Because need to add BitCrack as a new algorithm and enter the payment rate. There are lots of programs to calculate, but they do not add them. I think they are simply not profitable. It's sad, because this project that has a great opportunity to consider not useless PoW, but something real.
What about Amazon? 4x-10x expensive vs mining.
What about FPGA? 10x expensive vs gpu, but how many X speedup? (some info 10x, gpus equal, but electricity costs 10x profit)
