It all lies in computing power, currently I can reduce the range of puzzle #130 to the equivalent of looking for the public key of puzzle #103 without slowing down the search (my resources aren't useful for looking for a public key in range 103 anyway), I could reduce more but I do not have the necessary resources for it and the search becomes slow, therefore it is my "acceptable" range. It doesn't seem unreasonable to me that more puzzles will continue to be found this year by comparing what I can do with basic resources with others who have many .

in short, a puzzle for rich people
