...I clearly said that if it cannot save all the addresses then it should do its job and search for pattern and save addresses that match the pattern so tell me again does it not fit the "purpose" what is the difference by randomly brute-forcing the private keys and checking for the pattern and doing the same by taking millions of private keys? or will it lose its functionality by doing so?.
I think I mentioned this earlier but the main hurdle to implementing something like this is not the lack of talent, it's the lack of time potential devs have to write code & features and test them, since like most other OSS projects you usually don't make money until
after the modifications are done (and in the case of cracking tools, you don't even stand a chance then unless you have expensive hardware, so it's kind of a chicken and egg problem).
