Despite the high-speed optimization of modern hardware, the odds of "scanning" a valid private key with a balance are astronomically low. : A private key is an integer between 1 and tilde 10 to the 77th power The Timeframe : Even if you could check a quintillion ( 10 to the 18th power ) keys per second, it would take more than

These generate random private keys within a certain range. The "Keyspace" scanners that focus on the 2^160 space (RIPEMD-160 of public keys). These are essentially lottery tickets — astronomically unlikely to succeed. bitcoin private key scanner github
