Its a real shame really while these kind of programs can generate millions of addresses why not have a simple option to input millions of private keys from a text file that otherwise would take forever to convert using python to convert using gpu and save the output to text file or otherwise save addresses with the matching pattern along with private keys
Ahh, maybe because that's not the reason why these type of programs are written?
Based from your description, it's far from vanitysearch's main purpose: "
generating vanity addresses"
