A private key is a secret code that proves ownership of cryptocurrency. It's like a password for your wallet. Anyone with your private key can control your funds, so it must be kept absolutely secret.
This tool generates random private keys or scans specific ranges and checks if they control wallets with balances. The probability of finding a funded wallet randomly is astronomically low (1 in 2^256 for Bitcoin).
In 2015, an anonymous person created a challenge by sending Bitcoin to addresses with private keys in specific ranges. Many have been solved, but puzzles #71-#160 remain unsolved with prizes ranging from 7 to 16 BTC each (total ~1000 BTC worth tens of millions of dollars).

• Random key scanning has virtually zero chance of success
• Puzzle solving requires significant computational resources
• Never share your private keys with anyone
• Always use official wallets for storing cryptocurrency
