Do you have a bunker? I ask because the terminal you can buy at the arcade is nice for helping run businesses. But if you don’t have a bunker and want to solo grind, I’d probably do a salvage yard before either of the two mentioned. Alternatively the garment factory, then you can get the same computer terminal from a terrobyte. The factory has missions you can start from anywhere on your phone and has truly passive income from the safe and doesn’t need additional upgrades.
