The game's official description presents rebirth as a progression milestone and names a climb from Noob to Final Boss. That establishes the direction, not the complete mechanics. The launch guide therefore gives a decision checklist instead of a numeric threshold or a one-size-fits-all recommendation.
A rebirth can be attractive because many Roblox games exchange current progress for a faster future loop, but another game's pattern is not evidence for this one. The confirmation screen in your current Bid for Anime! version is the most relevant source for what resets and what the account receives.
If you cannot explain how you will rebuild collection income after the reset, wait and gather more information. A few extra auctions may or may not help; use your chosen cash reserve and current game state, not a promised multiplier that is absent from public sources.
