Wonder what strategy you manage to solve this puzzle?
can you tell us how you solve it?
Some math + kangaroo then some math again to reassemble the whole private key.

I suppose you divided the public key by 10 and then brute-forced A, and the rest is history. If A + B + C + D.

Not really, the key is between 2^255-2^256, so if you take this private key (integer): 62522620898388648159897954119572167059065661617885912620603899974102669643449 and divide it by 10 it will never be in 2**63, 2**64 bit range
