It actually is not useless. 026a0747b3229f32ce2f0f7bd77a7bd306f6c95d27e7c5bee22a417938d9988605 is the difference between the public key of puzzle 130 and the end range. Once you know it, you just need to subtract the private key of 026a...from the end range of puzzle 130 and then get the key of puzzle 130.
Congratulations, you just managed to subtract #130 from it's end range, I wonder is that all you learned in the past 2 month? So what the hell am I even doing here all this time if not teaching at least 1 person something useful? sigh!
Here, think of this as #130 :
000000000000000000000000000000034551231950b75fc4402da1732fc9bebf - 00000000000000000000000000000003ffffffffffffffffffffffffffffffff = 00000000000000000000000000000000baaedce6af48a03bbfd25e8cd0364140
Now you want to sell the third key above for 1
BTC? Do you have it? then solve the puzzle already, note the difference between the first key and the third key, if you drop the first char aka "3", you'd realize the rest of the characters of the first key have turned into a mirror version in the third key. E.g, "455123" is mirrored into "baaedc" now what is 0xb? in decimal is 11, so 4 turned into 11, 5 turned into 0xa(10), 1 turned into 0xe(14), 2 turned into 0xd(13) etc. Work on a solution based on that knowledge, figure out their difference in percent, it is a fixed value, no matter what, any number has a fixed difference value with it's mirror self.
0,1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f.
f, e, d, c, b, a, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.
Work on that instead of trying to sell your calculations, then you can solve it yourself.
