Thank you $upermoney for advice.

I just doubt about series number of puzzle, it is pick by manual random or pick number by using some formula (using math) or some algorithm calculate for pick number

I try already with both Pollard's kangaroo ECDLP solver C# and Python3 script
seem is still random bitcoin address by method buy is random by curve line (not normal dot random)
that is good idea for using random by that method pattern, and yes it is better than random by normal one dot pick

(but that random not solve by calculate series number list)
I just think about puzzle challenge for calculate formula for pick bitcoin address  private key or not (create math formula series? or make challenge to random to found bit coin adress (pick by manual pric by hand)

How many people still work on this puzzle next address? ( How many people give up?)
look like both thread not talk a massive a long time
