Now I have a question:
Is it possible to find collisions like this using B6 even if someone never generated an address with this method but we could find their private keys?
I even posted this on rico666 collision thread but he was rude and deleted my post.
I don't see why not. Either way you are using the 99 digits to create the private key so... this could work with any address. I hope no one tried something else like 0000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000002
Couldn't these addresses still be encrypted under BIP38?
