Hi!
I've developed a tool in Python that lets you manage large amounts of Bitcoin addresses/private keys along with seeing their cummulative balance. Includes batch address generator, which is also usable as a private key bruteforcer if you think you're lucky (hence the name, LOL). Tips and suggestions welcome.
