Background of my question is simply that I want to create a wallet that is as secure as possible but where also the address looks cool as generated by vanitygen.
If I wanted to create a wallet here now, how could I influence the entropy?
https://github.com/adrijano/Bitcoin-wallet-crackerSo, you want to have a seed which produces “nice” address for a given derivation path.
Testing addresses on the path is quite “expensive” operation, so the whole process will be much slower (less efficient) than “normal” vanitygen.
But I understand your doubts, you consider testing different seeds or one seed and different passwords.
