Why use this?

Rebirthing liquidates your assets. Executing a rebirth at the mathematically incorrect moment results in massive efficiency losses. If the projected time to rebuild your lost capital is shorter than the time you would spend manually grinding to the next milestone at your current multiplier, you should rebirth immediately.

The "Alt-Stash" Exploit

Pro Tip

Because a rebirth wipes your base inventory, elite players transfer their highest-value Brainrots to a trusted secondary account (alt) right before rebirthing. Once rebirthed, they steal the assets back, instantly applying the new massive multiplier to top-tier units.
