The pubkey is there so the private key can be found in a few seconds.

How?

He assumed the address was within 69.

Good morning, but how did you get the private key for address 19vkiEajfhnHnZjGpogP6Rv8sUQFvF7PiS, having only the public key?

Correct, I made the assumption that the private key for that wallet was in range 69. Since that address has 1 outgoing transaction, it's public key is shown. I ran RCKangaroo with the public key and got the hex private key under 5 seconds, with an RTX4070.

Code:

$ time ./rckangaroo -dp 14 -range 68 -start 100000000000000000 -pubkey 03f5c18f93f837065c3673b64f0426d08283d5097c54c465af92a399a017ddebc7
