Example usage

Trying our luck on puzzle 66:

./Coinhunter -t 0 -g --gpui 0 --gpux 256,256 -m address --coin BTC -o Found.txt --range 20000000000000000:3ffffffffffffffff 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so

Brute Forcing a list of addresses using GPU in 160-bit range:

./Coinhunter -t 0 -g --gpui 0 --gpux 256,256 -m addresses --coin BTC -o Found.txt --range 8000000000000000000000000000000000000000:ffffffffffffffffffffffffffffffffffffffff --in addr.txt
