Better than Gold, far below Rainbow.
Lock your base, buy one brainrot from the red carpet so cash starts coming in, and steal only from a base whose lock has dropped. Open the rebirth panel before you reset so you can see the cash and the exact brainrots that rebirth will take.
The rebirth panel takes the required brainrots and most of your cash. Since Update 66 it no longer takes every brainrot in the base. Brainrots still walking to your base go back to the red carpet. Gear from earlier rebirths stays, and you gain that row's multiplier, cash bonus, extra lock time, and any new slot or gear.
A brainrot can have one mutation. Traits stack on top of it. The mutation article's worked numbers add the multipliers together, then multiply the base income. A $65M/s example becomes $81.25M/s with Gold (1.25x) and $715M/s with Cyber (11x).
